These lectures are clearing all my little doubts like no other KZbin tutorial ever did! Thanks a lot for this series and please upload more stuff on C, C++ or maybe even Python! This channel is a blessing, thanks a lot

[@gnesoni3349]

best way to explaining basics, such a type of simplicity

[@castiel0504]

Since I see few comments out there that contain this error - " undefined reference to `increment' ". Maybe you are not using Code Block as me(Visual Studio Code here), or whatever IDE of your choice is, you just need to add #include "add.c" in the main.c . Hopefully this helps someone in the future.

[@aniketkumre4231]

plz explain it

[@jonaxkariuki]

just declare the increment () function in the main file

[@sahraouibekkai423]

[@abdelrahmansayed4865]

I want to thank you very much your explanation is impressive, I have watched read a lot of videos explaining the static keyword and the other modifiers keywords but sir your the best, there is a little suggestion that is to draw Memory layout to make students imagine how the program flow, again thanks for your big effort

[@vanditdubey]

I seriously think these lectures are not for any noobie or a complete beginner. These are useful for the programmers who have a basic knowledge of C or any other programming language. They have explained all the concepts a little bit early so basically what will happen is everything will bounce of your head. So I recommend you to first learn the basics then come to this channel to furnish your Skill cause they have an amazing knowledge and they know what to teach. But first the basics !!!!!!!!! Go Learn them and then come back here......………….

[@josuegisber8150]

Great Job on explaining this lesson! But one question that came to my mind was if stactic is constant, how come you can update its value? is there an explanation for that? or did I missed something? Again, thank you so much for the hard work you had put on this series of lecture. I'm really enjoying it!

[@porankirajkumar4709]

When you declared the vairable globally without assigning the value should be 0 so the value is 1 and when we called the increment function again we go to the function and the variable is global is not changed then how the value becomes 2??

[@hemangmitra7346]

In add.c, I have not initialized the count variable like *int count;* after running I get the output 3 how ?

[@petar7867]

note, while you cannot initialize a static variable with a variable, you can still assign to it a variable later on.

[@ritamchatterjee3307]

sir,what stdlib header file works for

[@rachanajingade3925]

Hello sir, How did you access count variable in main.c from add.c when it is declared as static int count? When you said that static variable can't be accessible outside the present file?!

[@shubhamthakur3706]

hes not accessing the count variable in main.c but hes calling the function...so whatever the value is being returned by the function(return command is giving the number stored in variable) ...that value is being accessed cuz return function is doing that....variable count is never being accessed by the main.c

[@intelchip_x86]

@@shubhamthakur3706 exactly

[@josuegisber8150]

when I call the function increment in the main function file it gives me the error: "Implicit declaration of function 'increment' is invalid in C99". To fix it, I have to declare a prototype of the function in the top of the file... Any reason why your work and mine don't?

[@venkatavinod2798]

auto,static,extern,register are storage classes or modifiers??/

[@dipesh1401]

you are a genius😎😎😎😎

[@roshankumarparihar6104]

how i get to know that that is a automatic integer. i mean it is true always that every variable is auto please ans if u understand my que.

[@aravindperiketi7540]

why we assign static constant value, why cant ?could you please tell what is reason behind hit

[@baratammadhan1239]

Sir, Please make the videos of Mechanical engineering subjects

[@lohqingzhen]

Why we no need to include the add.c file in main.c in order to use the function? We need to include the file, doesn't it?

[@paritagojariya5300]

Hello there, Thanks for your great work. I'm trying to do the same thing in visual studio code. It's given me an error undefined reference to 'increment'. Can you please tell me how to solve it? I've tried but couldn't solve it. Thanks in advance!

[@sadafaafreenansari6099]

Add #include "add.c" in main.c file

[@compangit1524]

Commen for myself: Review that global variables are automatically initialized to 0. Variables uninitialized and local to functions are assigned garbage value. Putting static keyword before a variable makes it visible only to its current scope. For example, a static global is only visible within its file, and a static inside a function is only visible within its function. The static keyword also assigns an uninitialized variable inside a function equal to 0 instead of garbage. Static variables also don't get destroyed after a function call. Static variables can ONLY be assigned constant values. Static means occupying fixed memory

[@neerajr8182]

Point 3 in the take away is inaccurate. While you can initialise a static variable only with a constant or a constant variable, you CAN assign static variables using function returns or other types of variables.

[@harisrik2082]

Team, kindly upload ALP playlist fully

[@Abi_Mehandi_Arts]

sir i have a doubt how the compiler understands that the add.c file which is used for increment here is in another file without using a "EXTERN"modifier... and also... is the function repeats three times i.e. whether it is performed three times... then output must be 1 1 1 please explain sir.....

[@anweshamandal6058]

only 1 printf statement is present

[@rohinishah1294]

How can we reassign value to the "value" Variable...?!!!???

[@liksondebnath4901]

how can i link two files in vs code?/

[@nikhilanand984]

sir so extern can access both global as well as local variable?

[@sourabh8748]

Yes

[@friendsfandom]

Well I had doubt in add.c you did not specify any header files y?

[@meghnachowdary]

Sir, when we initialized static int count=3; How we still got output as 6? i. e. Even if we initialise it as 3, can static still retain the new value?

[@lekshmipriyasb5055]

initialized as 3,and incremented 3,total is 6

[@harshithagowda3707]

When STATIC makes it private ( where other file can't retrieve the value) then by making a command how will we get the O/P as 3 ??

[@lockdowntrendings1207]

Is it possible to create a c program without main function🤔

[@aneeltripathy7420]

Isn't a word initialized to a constant value isn't itself a constant ?

[@amruthaganjam4968]

cant we do soo...like this for incrementation i= 1 ; i < = 10 ; i ++....uhu..if we write this by using orintf and scanf the output will be 10 time like if i write my name in during run it will show my name 10 times.... i said it since code should be very very small soo

[@Official-tk3nc]

Guys they are providing everything for free and some idots dislikes these types of videos. I think they need mental treatment

[@vinun2163]

Since v r uing two file... We have to use "Extern modifier" then only the linker come and combine the this to file know... Sir

[@narmatharamasamy3019]

Its only for variables, not for functions, functions doesn't need an extern keyword

[@sahilpatil8287]

@@narmatharamasamy3019 thanks dude you just solve my doubt👍👍

[@sathvikswaminathan7933]

How is your program running without errors since you have not included add.c in your main.c file?

[@fortnitelove8129]

Absolutely i had the same qn. Actually he is using codeblocks IDE , and it has a feature if all the .c files are under same project directory,than no need to explicitly declare the add.c file in main ()

[@pratishthachaurasia6326]

Auto variables are given garbage values if not initialized with a value. By default, variables are auto variables. Is a global variable, not an auto variable? And if not initialized, does it get garbage value or 0 by default?

[@zakirahimi7924]

static variable is not global (though it can declared globally in a file then it is accessible to all the blocks and functions of that file) it is local to the block of code where it is declared or within the function its declared, its lifetime is throughout the program even if it is declared local to a block of code. ""this is the example of a variable is alive but not accessible""

[@adithyagalipelli2934]

How are we accessing the "count" in main.c without using the extern modifier?
