What happen if we don't use return statement?

Answer 1

If your function doesn't return anything, set the return type to void.

void print(int n) {
cout << n;
}

Similarly, if it doesn't take any parameter, put void in the parameter field.

int get42(void) {
return 42;
}

Answer 2

In the main function, nothing may happen but it will be difficult for you to even notice a logical error in
your code since you wouldn't be able to see the required value returned after program execution.
