PassByValue

Question

How do you do the pass by value question?

Answer 1

Pass by value:

void value(int a) {
a += 5; // only changes a inside the function
}

By Reference:

void reference(int& a) {
a += 5; // changes the passed variable
}

int x = 10;
value(x);
// x is still 10
reference(x);
// x is now 15

Answer 2

How should anyone know what you're even talking about?

Answer 3

normally 'pass';
if(x==2) pass;
and finished...
Is that what you want to say?
