Question

Which is the correct way to specify a reference. I know both works with the compiler, but wanted to know the correct way since I have seen both in code bases.

void Subroutine(int &Parameter) 
{ 
    Parameter=100;
}

OR

void Subroutine(int& Parameter) 
{ 
    Parameter=100;
}

Answer 1

There is no ‘correct’ way, in the same way like there is no ‘correct’ way to place your parentheses and brackets. It’s a matter of style and preference.

It’s more important to be consistent.
