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

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