Buckys C++ Programming Tutorials - 13 - Using Variables in Classes

[@derekroot8043]

This video goes over a programming concept called "Encapsulation". If you're still confused about this, just do a youtube search for it and you'll learn more. Also, there tends to be confusion about Functions vs Methods. One naming terminology goes like this. If a Function is nested in a Class, it's called a Method. If it's not nested in a Class, it's just called a Function. The reason for these two names is that it makes it easier to talk about functions. If someone talks about a method, you know immediately that it's attached to a class and must be assigned an object to be used. On the other hand, if they talk about a function you know that you can just call it directly. I hope this isn't too confusing. =)

+Khatia K ha try almost 12 years lol. Well i guess 5-12 if you count college. Tho most of this stuff i already knew by now but he definitely is clearing some stuff up for me; my experience having been limited and depressing.

[@steve122288]

actually theres alot of stuff i always wondered that he doesnt explain. Like to what depth can the program function. Like this string library is needed in this video; makes you wonder where int and double ect come from and how it knows to utilize functions and stuff. I wonder if learning C wuld help. Tho i know that understanding computers and science in general more would also help, despite that I need to progress further in my projects lol... at least im learning science on way or another tho. This is always better then nothing.

[@Legendofmudkip]

steve122288 There is actually a "don't know, don't care" rule-ish with programmers. My professors all follow this rule and Bucky does as well. How does the library work? Don't know, don't care. How does a program actually work? Don't know, don't care. I was taught this in my first CS class. It is a shame though because I sometimes wonder as well, how things work in C++.

This was the hardest one to follow so far. After watching it like 6 times, and pausing it so I could see the full code, and writing it 2 or 3 times, I think I got it now. I think. Would have been better if you described in detail what each line and word or whatever was doing, though. I had to run it through my head a few different times before I was able to make sense of it. I'm still a bit of a noob, but here's my understanding of it: class DrunkMan{ public: void setName(string x){ name = x; } string getName(){ return name; } private: string name; }; int main() { DrunkMan object; object.setName("Lemmy!"); cout

[@Aura1002]

+Mechaghostman2 Dude we need you on every video... I understand this loads better than trying to write it down myself.

[@yumi3088]

I think it would take time and experience via coding till we can actually use this technique efficient. Hopefully we all can, coz it would be a great help to shorten the code.

[@AndyU96]

My initial problem was with the 'setName' and 'getName' thingies, after a while, I realized that these names could be changed.. When someone types things like 'set' and 'get', it just gives me the feeling that it's some specific code/type/something like that

[@Sukidarkra1]

thats not an object that is a second fuction in the buckysclass. String getName(){ is the same as the "int main ()" line of the main function all the fuction does is gives the main fuction the name so that it can be output in the last line of code.

[@ClaudiuB]

Let me explain it to you better: He wanted to access the private variable in BuckysClass from outside the Class, and for doing this he made the variables above public(but put them in the same class aka body of the class)! The rest of the code is just the main program which simply create a string and print it out :D

[@KillerPiplup]

[@hefhef54321]

I had to watch this twice to get what the "string" was all about. It's basically like "int" but for text variables...

[@zoo2322]

thx dude

[@epicwhat001]

not really int is a primitive data type and string is an abstract data type think of string as an array of characters wrapped up in a class.

[@zoo2322]

Thx!

[@cameronsluiter323]

Question: Why does he use string? Couldn't char work too?

[@iantupiara891]

string is used for more than one character, while char is just for one character, so for example if you made a class of college classes, it would be correct to put string name (for instance Math), and char grade (A). I'm a student as well, not 100% sure that I explained it correctly.

[@Shadowrose54321]

Pointers 1)The compiler(What your putting the code in) Reads the entire Class before giving an error. So creating a set function Name first will not give you an error. 2) If you are having problems reading this code read it from bottom to top after he's done 3: String x is exactly like int x in the parameter videos. String = text. 4: Name = x is changing Private: String name; to Private: String X; 5: Return Name returns the name variable to you. So when you use getName in the main it will also allow you to display name. 6: Bo. Setname("Whatever you want here") you are now officiially using setname to change X(name) without accessing the private function 7: cout

Great refresher. I took "C" in the 90s. It's longevity has been truly amazing. Prior to "C", it seems like programming languages morphed every several years. I got thru vids 1-12, basically clicked thru them. This is new material but I recognize it from reviewing recreational programming material.

[@lolittashue2480]

Can't we set and get the variable using one function instead of two? like: public: string SetGet (string x) { name = x; return name; }

[@MrHarryGaming]

Fair enough. Haven't made a program yet where It's needed this set up, but I'm not working on anything but basics right now. Good to know for the future at least.

[@RealEyes24]

do functions return strings ? as i remeber functions do not return strings or arrays...

[@nicholasgugunga2549]

functions return them if you program them to do so. In C++, AFAIK, they at no point do it automatically.

[@lucasagua77]

okay it was a video incredibly hard to follow. but if it says that public classes will mess up our programms i will willingly take the plane train and bus to do the private thingy. i have one doubt tho. is char and string the same thing? can someone explain to me what the heck is an array too?

[@thesickbeat]

I'm not sure if you've already seen how property's work with events but once you got there you need to know that the big advantage you get is that you can set an event in the setter. So whenever a variable is changed the event fires. That should clear up alot.

If a computer runs through the code top to bottom, how was he able to use the variable "name" in the function getName and setName before the variable was declared. Shouldn't he get an error?

[@Raidom]

Maybe it reads class from private to public ?

[@KeenanWoodall]

Thanks

[@SrJusty]

I have the same doubt and I think Otto Ling didnt answer it. What I want to know is that in class buckysclass there are two functions that use the variable name, but name is declared later, how is that he doesnt get and error? How know the functions setName and getName what the variable name is?

[@luisaverhoff4884]

I know this is pretty late but in case you don't know, no it wouldn't get an error because Bucky executed each calling function in the proper order. When ever a program is executed, the main function is first called on, then it reads any variables there are initialized in the main function(very important). Next it reads each calling function( in this case setName, and then getName). In setName, he initializes the variable string x with Sir Bucky Wallace and then is stored in the string name variable and then is returned by the getName function. The name is then finally displayed on the console screen. This is order the program goes by. I hope this helps.

[@vish4544]

You set name=x before declaring it (you declared string name in private which is down) why no error???

[@crads3291]

name = x is the same as saying x = name. He declared x in "void setName(string x)"

[@mohdkumail5629]

You can use variables that are private in the the same class but not in main function.

[@Sakuscribe]

+Jav Reborn if you say "name = x" then name contain the value of x. If you say "x = name" then x contains the value of name.

[@Sakuscribe]

+Mohd Kumail He's asking the order of operation. Since he declared the variable name after he assigned it the value of x, why does it not give an error?

[@mohdkumail5629]

No there is no difference the computer knows that name variable exits in the same class as the function. As long as it is in the same class as the function there will be no error.

[@Mila-w6d]

If you look up "encapsulation," youll be able to find more information on why this is important. But basically - if your class variables are public, they can be accessed from anywhere in your program, even accidentally by another class that uses the same variable name. Keeping class variables private helps to keep things organized. When you would like to change the value of an objects variable, main, or another object, passes the variable to the object, and the object sets its variable itself.

[@БатоЖигжитжапов]

Programming drives me crazy!!! I'm sitting at 2 am, trying to create a programm like this, searching the video like 9 times and finally, find the problem! Just spelled the object wrong once!

[@samesam15]

doesn't it mark where you had your error in CodeBlocks?

[@romel_storm]

Yeah but sometimes the errors carry through and cause other lines that didn't have errors to have errors because the line with the original error was wrong if that makes sense. The compiler just spits out everything that it found that was wrong

hello, what is the difference between setName and getName? i am confused about the two.

[@KS-2317]

+Peterolen why can't we use return name; In setName function ?

[@juanbermudez9643]

+Peterolen setName and getName are both functions, and Bucky made them public in order to have access to the variable "name" which he made private, and he wont be able to use it otherwise. so in the function setName, (which has a return type of void, void means the function will not return any value) Bucky passes a parameter x which is of type string, and in the statements after the {} he defines name = to x. void setName(string x) { name = x ; } So when bucky calls this function in main bo.setName("Sir Bucky Wallace"); the function will contain the string "Sir Bucky Wallace " In string getName() Bucky returns a string, which he placed before the function. string getName() { return name; } as you can see name = " Sir Bucky Wallace" In conclusion Bucky used the functions to access a private variable. So when he couts and calls on the function cout

[@SuperYtc1]

setName sets the name. getName gets the name.

[@sigfridsixsis3255]

“Sir William Wallace”==“Braveheart”

[@prmchuk]

Now to get around this problem, you have to create a PUBLIC function that can be access outside of your class, in main. Because the function is usable outside BuckyClass, you then code the function so that it is able to change the PRIVATE variable you created earlier. By convention, a function that does this is called a setter. Every setter, by convention, has a getter function. The getter function is also public and all it does is retrieve the info that is contained by the PRIVATE variable

[@wiredelectrosphere]

What's with all that "I am 5 - 12 years old and i am fluent in Java, C, and 100 other languages, including machine code" in every single programming tutorial on youtube? And not only programming tutorials, also in math tutorials but not as often as in programming tuts.

+Hermann Bernzweig when i was 16 i designed a shitty ass turing machine, im a genius, PRAISE ME!

[@Seikuu]

Okay first the "string" part is an identifier, like int or void, but since this is just for text, it's string. Then what it does is essentially like the usual return (x or whatever you want to return) in any function. The thing is it just returns name, which it already has access to since it's in the same class. Basically the function is there so you can use name from the class with just that after it's already been set some text,instead of going through a function where you need to add the text

[@fl3tching101]

A public string can be directly accessed by say typing bo.name, whereas a private string wouldn't be accessible, it's just good programming technique and saves you some trouble in the long run. Also makes it less likely to accidentally make syntax errors with the string.

I actually learned how to code by following good tutorials on how to make a certain type of program as they explained how it works. But what you advised is still good because still today (been programming for 6-7 years now) I put in comments to refresh myself on how the code works. :)

[@mrninjaman96]

because if you can brake down some process in parts (function ) do it later on it's much easer so you can set name few times without returning it and when you want to return it you call get name so you don't need to set it again it will be clear when you get to more complex problems

[@bishalshrestha1422]

i had no hope in passing c++. But this tutorial made me class topper in weekly test. thanks bucky....

[@ihr1414]

@BarrieIsEpic Yes. C++ is a strongly typed language, meaning you need to define what kind of value will be held in each variable. It could be a bullion, word or number, but each one requires a different variable. Many newer languages, are weakly typed, which means that any value can be entered into a variable. Although it appears more difficult to name the type of every variable, it gives the programmer more control over the program and garentees every variable will serve what it is meant to do

[@dangerface3171]

I have had 4 people explain this to me, but only you made me get it! Thank you and keep up the good work.

decompilers can get it, making functions and variables private is done so that you can make two function of the same name. plus, it makes the code "feel" a bit more organized.

HEY NOW YOUR AN ALL STAR !!!!!, jokes aside, thanks man , you are getting me through college!! Cheers to your hard work. You can see the difference from somebody who is just making videos on the side and then people who put a huge amount of effort into their work.

When we are programming these simple programs it may seem useless to have indirect access. But when you are making larger programs, you will have many many more variables and functions. Things may get confusing and muddled up. The last thing you want is other functions accessing and changing variables. This is why it is "better practice" to use get and set methods. It is not 'wrong' just tidier and gives less room for error. :D

[@-mustang-9383]

could you reexplain why it's become a bad Thing, when you didn't put the 'Private ' into the Code? i still didn't get that part clearly enough... would be there any examples between putting private and without private to clearly state the difference ? thank's

Some of the reasons to do things this way is so you can say, check to make certain the length of the name string is valid, you can do this in the class without changing any other piece of code in your program! The *setName()* function is still the same, but now it could include code to check the length, other error checks etc. It can be modified at any time on how to handle setting names without you changing any other part of your code where it sets it, only the class itself needs to be changed. On tiny projects like this it doesn't make sense, but if you're working for a living at this, or even on your own on a large project with multiple files which could have a large number of calls to the same class, you want to be able to adjust these things by only changing one piece of code in the class and not have to search down every area in your code where you used it. It's also more secure this way, you can enforce limits in your class etc... just countless reasons to do it this way, the right way as he described. Oh, one other note, in a class, everything is public: by default, there is no need to actually enter *public:* in there, just put all your public functions first, and then put in the *private:* keyword along with your private variables etc... after it.

I've been following along with your tutorials and changing "Bucky" to "William" so I typed out "Sir William Wallace" and got a good laugh when you said it out as I was thinking it.

[@stopmotiontacos]

I know it's tough, what helped me to internalize what he said was writing my own program that used the things I learned in the video, i.e. making an Object Oriented simple calculator.

[@faizanbaber]

Bucky you beauty!!! Really appreciating your all these tutorials.. you just saved my ass in tomorrow's labtask

[@tienhunglam240]

i'm a newbie from VietNam, what u teach is easy to understand. Thanks a lot

[@Dooskta123]

x is just a random variable chose to represent a value. x in this case represents whatever string is inserted in bo.setName(); We decided that x would represent it when we said void setName(STRING X) and that is linked to the bo.setName() object.

[@prmchuk]

The reason is because Bucky is showing a really simple program that uses a class. A class, really is used to do something really really really specific in your prorgam. And instead of writing the code for something that specific in your main, you create a class for it because its so specific. For example , you might have a program that compares Polygons and so you might create a Rectangle and Triangle class that sets and gets the length and width and a function to find the area and perimeter.

[@fairyrarity6953]

I wanted to say thanks! Your tutorials are pretty much carrying me through my C++ class.

[@pinkhippie135]

If you use variables as public, it is very easy for some to use that same variable in another function, which would then change all the variables with the same name to the same thing. If each is set specific to their respective function, then you can reuse the variable name while it still being considered a different variable. Like declaring x as a variable in main and then in buckysClass, they are two different variables with the same name, which should hold different values

[@asifkaka5052]

Thanks to you bucky i got 91.5 Marks in my first semister.

[@Moonz97]

because sometimes you dont want to change the name and you just want it to show up like : cout

[@aikolt1217]

Thank you very much Bucky,you made my learning very easier and i always learn from your videos and seems like i have attached to your videos and you made my life brighter ,you are Genius!

[@Emsee88]

Question: Why do you still need to keep the Private Class with String Name? If your cout

[@aronreviour9164]

keep it up. i dont know what i would do without your tutorials.

[@moszczynskieng]

Excellent video. You have made so much code I have been looking at today make real sense! Thank you sir!
