Help with functions assignment

[sambix]

On line 28, I keep getting an error message saying "uninitialized variable b and c" What am I doing wrong??? I initialized a, b, and c, but only a is getting accepted for some reason...

Line 26

    cin >> a, b, c;

should read

    cin >> a >> b >> c;

The comma operator has rather specialised uses, its use is often misunderstood.

I initialized a, b, and c

No, you didn't.

	int a;
	int b;
	int c;

There is no initial value given here.
