Type of Functions
When creating a function, the data type of the return value must always be specified. In the main function, the return type is declared as int, indicating that it will return an integer value upon completion. In most cases, the main function returns 0 to signify that the program has successfully executed.
main
int main() { return 0; }
Note
Since the
mainfunction is reserved in C++, it will always return integer.
Custom functions can return any value, but it's essential to understand that the type of the return value must match the specified return type in the function definition.
custom_function
___ custom_function() { return ___; }
