The following function mixes call by reference and call by value parameters.
void T ( int & a, int b )
{
int c = a - 1;
a = c + b;
b = a + 2;
}Suppose that in main we had the following:
int apple = 10;
int banana = 20;
T ( apple, banana );
cout << apple << " " << banana;What is the output?
a) 29 20
b) 10 31
c) 29 20
d) 29 9
e) 10 20
What do you think is the answer? Did you compile and test it for yourself? If not, why not?
It's the same old story - http://www.daniweb.com/forums/thread161400.html
Try it, and find out.
Otherwise, we might just start lying about the answer just to see if you'll believe everything we say, only to find yourself with a crap mark on your assignment.
