What is the Difference Between return 0 and exit(0) in a C++ Program

In a C++ program, the main function often returns a value to the operating system. Usually this is accomplished by using the return keyword. However, we can also return a value by using the exit keyword. This video explains the difference between leaving a main function with return vs exit.

Sir i understood the difference between exit and return .but why to use return or exit?

[AdamDjellouli]

your videos deserve much more attention

[simonmaracine]

exit is not a keyword, it is a function.

Thank you so much for this video, i could not get my if statement to stop running in my function!!!

Are there any videos where I can see "return 0" used for the purpose of telling whether a function worked successfully or not? I've seen that explanation given many times for why "return 0" is used, but I'd like to actually see an application where that turns out to be useful.

Hey just wanted to ASK if you are still going to make vids?

[grihabor]

Why the video is called "... in a C or C++ Program" but the difference is shown using classes, which are only in C++? Is there any difference in C?

[selvapriya]

if main prgm return 0 means prgm run success (true) if main return 1 or retrun -1 means ???

[selvapriya]

What is the difference between return 0 and return 1 in main function ?

[ivaemply]

Could you have done the same a "for " of "while " loop intered of the "do" loop.

[Shadow]

Would an operating system also deallocate dynamically allocated memory?

[basseygodwin]

Pls what compiler are you using in this video?

[xCwieCHRISx]

you cant use return outside the main function to exit the programm.
