C++ Programming Tutorials: 13 Functions - Passing Variables by Value or Reference

[@gceda8595]

Sending thanks from 10 years later. Your explanation was very helpful and I understand the topic now. Again, thank you!

[@williamrubi4326]

Taking my first embedded class and found this video. I wasn't confident with functions being passed by value, therefore I did not understand how to write my hw code. I watched this video right now (1:30am) and not only did I feel much better on the topic but, I also was able to write code and complete my hw understanding everything I did. Truly, thank you. This video was put up 8 years ago and is still saving students. Thank you.

[@esdenaze]

I applaud you for repeating and leaving in the errors. This makes it realistic and less frustrating to learn. Good teacher!

[@Ammeeeiizing]

I like the fact that you go through all misstakes too! Makes it easier to follow the whole process. Thank you !

[@christinasarah2766]

GOD bless you. This tutorial is authentic and straight to the point. Keep up the good work!!!

[@sakitech]

Because you are shipping variables outside of the main function. When they come back to main, I want the modified versions to come back. Then I can resend them out with updated values. You need ampersand sign anytime you want to modify the ACTUAL variable.

[@AYHA0]

thank u from the bottom of my heart u made what i coudnt understand it in 4 month in 20 min easily

[@Dani98664]

Spent an hour trying to get this information. So glad I found this video!

[@tobiasrodrigues1]

Thank you so much. I watched other videos where I got all the basics and still didn't get it. I finally understand and you made it so simple. You really helped me a lot.

[@Raulz713]

Thanks very well explained. Just finished my Programming Fundamentals class and these videos are great as a refresher.

[@Eeeppy]

Thank you so much for this tutorial....You don't jump around topics and you present the material very thoroughly. I appreciate it. =)

[@ernestogarcia8351]

nice video!!! 9:50 - end was extremely helpful , I am now ready for my quiz!!!

[@techiquirl]

This is the best tutorial I've seen for udf variable ever! Thank you!

[@asemnafiz]

Best explanation ever! Been confused with this thing since yesterday....been going through notes, textbooks and other youtube videos and finally I got it. Thank you!

[@mydearpcy]

thankyou mister. You are very good at explaining and make me more understand about this topics. Much of helps!

[@plastic27life]

clear and to the point. you've been a blessing

[@Rizwaannminhas]

Thankyew brother. i understand this topic frm only one video of yours. Thanku again !

[@shahuzinlafeer533]

Thank You very much. i was struggling with this concept and thanks to your video everything is now cleared. well done!!

[@tykechingching]

Thanks for this video Sakitech. I was struggling to find material to help me with this topic, but you did it so clearly!

[@_DarkKnight2301_]

Amazing video. Was trying to find something like this for a few hours because I just wasn't figuring out how to do it. Currently in an intro course and I'm jumping ahead and trying to make a slightly complicated math practice program using the basic arithmetic operations. This is hopefully the final key I need to really build the design I want. Though I do need to figure out how to stop the program from breaking when a char is entered instead of an int. lol

[@aydinahmadli7005]

greatly explained, and informative video, thank you!

[@kzukijn]

Hi Sakitech... thank you for this tutorial. I cannot finished my Homework done by time if i haven't seen this tutorial for functions. Been stuck for 2 days working out on it. The book is so flat that I couldn't understand it. Thank you! Keep it up!

[@brettnieman3453]

Way better explanations than my actual C++ class!

[@arifhakiminadnan4880]

a very clear explanation , u deserve to be a lecturer

[@winterslee]

Thanks sakitech , it helps me a lot

[@WinningBURRIT0]

This video saved my life. Thanks man.

[@brandonfarr5638]

Thank you so much! That was a really great analogy comparing the reference parameter of a function to shipping an object, in order to get it modified.

[@gmartshopper]

Wow, this tutorial was SUPER helpful!!! I was having trouble figuring out the difference between passing variables by value vs. reference. Thanks!

[@KittyKode]

crystal clear explanation ,tnx man

[@danyalfayazi8804]

thank you so much. god bless you you have no idea how much you thought me.

[@oliffx1]

Good stuff, you explained much more clearly than my lecturer!

[@amaliavina4029]

Excellent tutorial!!! Thanks,

[@bryankim7966]

outstanding tutorial. I was screaming the whole time when you mispelled "calculate" though

[@venzeti]

Honestly, thank you so much!!

[@Esther010]

Thank u very much, I appreciate it

[@NicoEstebanR]

Thank you so much this helps a lot

[@Stangil1]

Very good video.

[@adibaiman570]

thankyou so much sirrr !!

[@npn7564]

very great tutorial.

[@Kevin0594]

You.. sir.. are a LIFESAVER, THANK YOU

[@mamuchjero9199]

Construct a function named pass() that accepts a double precision arguments - the mean tolerance of a group of parts and returns a reject or accept code depending on whether the mean tolerance is less than or greater than 1.0%. If the mean tolerance is less than 1.0%, the function should return an A to accept ;otherwise, it should return R to reject. how can i solve this ?

[@sakitech]

Coming soon, sooner than a week.

[@bhaskarchary6683]

will you please show me the debugging procedure to find bugs in c++ with embercadero tool

[@sirpj6955]

Great video! Thank you

[@gerardomarchetti6634]

Thakns man!!! you save me !!! :D

[@Basedeath]

What if I want a function to add to a variable in the main instead of switching values with it?

[@andriyblyznyuk5590]

Hi. I have a question. So if you would not pass value by reference, then int number1and number2 would remain 0?

[@sardorbekmuhtorov7018]

yeah i think so , idk how it is working

[@BEESkneesz]

Have you done arrays?

[@lemmeleeds5291]

Thank you so much .. it helped me a lot... (love from pakistan)

[@gjohnson1194]

great video

[@informativecontent4778]

Thanks man

[@Matice21]

Why can't the function definition and prototype be above the main(); function?

[@ap-lq1cq]

Whats the use of prototype?

[@BumsInChocolate]

This guy is a legend

[@NicksLocker]

Thanks!

[@abdiwahabadan1817]

very simple easy to understand, thank you i wish you best of guidance from Allah and best of guidance is Islam.

[@yuesun3935]

thank you sir

[@RimSelektaMusic]

Thank you

[@mamunbinrashid4635]

#include using namespace std; void input(int ,int ); void calculate(int , int , int ); void print(int ); int one,two; int total; int main() { //int one,two; //int total; input(one, two); calculate(one, two, total); print(total); } void input(int , int ) { cout one; cout two; } void calculate(int , int , int ) { total = one +two; } void print(int ) { cout

[@BURU1994]

can you make a function that takes two inputs arguments and provides two separate results to the caller, one that is the result of multiplying the two arguments, the other the result of additing them.

[@c0ntender1]

why am i getting a total of 0 zero on display

[@ShaunJW1]

Thank fuck someone could explain this to me, when im a billionaire ill send you a Ferrari good sir!

[@samjones8573]

Sir I want to learn C++ functions

[@amirulyusoff4338]

is there any way to use instead of using "&" ? anyone who know feel free to comment. I have to do my assignment. Thank you in advance.

[@festuskemboi4257]

it was awesome

[@thenoobsterman]

proooo-toeeeee-typeeeee lol good tutorial though. In the last part is it even necessary to pass total to print_Results as reference? You dont modify it in any way you just print it.

[@BDC2K]

Only put the data type(s) in a prototype's parameters! Example: void print(int x); // Wrong void print(int); // Correct

[@BDC2K]

There were so many errors in the video, that I realized that I don't want to comment every single error, it's too much work...

[@rowel9785]

I don't know where ampersand is in my keyboard :(

[@shariqkhan4627]

so sad

[@kenshinhimura8708]

9:30 “Don’t try to learn this while you’re taking C++...” Too bad they force you to try and learn it at that point 🙃

[@dalalalghomlas1600]

could you talk about reference in more advance way ! i need to know the root of this please!

[@LK-pc4sq]

I think he is good, repeats so we can absorb it. Btw, text after (int x) is grey and very hard to read. I cannot see it. It is a //comment. Could be my laptop screen it is a anti glare screen so not sure.

[@user-pb8qi2yy7f]

videos are good but plz increase clarity

[@raginibhayana1117]

why do we need a prototype?

[@chikipichi5280]

Damn I could tell this was explained very clearly and I still don't get shit

[@thatcosmokramer]

>sees that he types endl; instead of NO

[@HardNougat]

Thank you! It never occurred to me that a function doesn't actually change the value of a variable in main...that is unless you use pass by name.

[@sakitech]

HardNougat Glad I could help!

[@plastic27life]

Very Helpful -struggling Comp Sci Major

[@Jaime-II]

how you doing now?

[@mobarakjama5570]

Who else is confused.

[@anonymoususer7663]

You're using global variables!! 😡🤬
