Is there any code/keyword for return number WITHOUT using return keyword ?

Question

We can return values/char/string with using return keyword.

Answer 1

Passing variable by reference to function and altering the value from there?

void func(int& Val)
{
Val = 6;
}

int main()
{
int ori_Val = 10;
func(ori_Val);
std::cout << ori_Val;
}

Answer 2

In Python there is also a yield method, which you may exploit as returning values...

Answer 3

Or globals.

Answer 4

And at least in C++ and Java, you can throw and catch stuff.
