Should I return 0 or 1?

The values 1 and 0 are of type int and are not implicitly convertible to boolean . So when you return 1, you are basically returning True as the final value of the function while return 0 is basically returning False as the final value of the function.

Should I use return 0?

What happens without return 0?

Absence of return statement will never raise compiling error. Especially for main function, that handles differently.

Is return 0 false?

Zero is used to represent false, and One is used to represent true. For interpretation, Zero is interpreted as false and anything non-zero is interpreted as true.

Does return 0 actually return 0?

It doesn't have to return 0. It is an error code. The program or batch file that called it can look at the error code and know if the program ran successfully or failed. 0 means the program ran with no problems.

Why should main return 0?

“int main” declares that the main (program) function returns an int. return 0 is to return the integer value 0 which generally means the program completed successfully.

Is return 0 the same as void?

ANSWER. The reason for the error/warning message is because a void function, by definition, does not return a value. When you include the return (0) statement, you are saying that the function returns a value of 0. This presents the compiler with a contradicting declaration and return.

What is return 0 vs return 1 vs return?

Return 0 means that your program executed without errors and you don't have to return it explicitly, because that'll happen automatically when main terminates. Return 1 means that your program had an error. No difference at all.

Does return 0 break a loop?

In your case,since return 0 is placed in main ,the program will exit. return will terminate the execution of the function and returns control to the calling function. When it is placed in main , it will exit the program.

What is the difference between return 0 and return 0?

Difference between exit(0) and return 0 in C++:-
