One way is like this:

1
2
3
4
5
6
7
8
9
10
11
12
 
void findMin(double& lowest, double n1, double n2, double n3, double n4, double n5)
{
	lowest = n1;

	if (lowest > n2) lowest = n2;

	if (lowest > n3) lowest = n3;

	if (lowest > n4) lowest = n4;

	if (lowest > n5) lowest = n5;
}


Then when you call findMin(), the first param is set to the lowest value. This is passed by ref, the other params can be passed by value.

Same for the other required function(s).

Isn't it nice (not!) when the OP removes all of their posts after they have got the code working.....

Who was the poster? Just so we know not to waste time with them in future.

I don't think the OP removed their posts. More likely that they got reported because they edited the question out, as a result the posts are removed and the account goes to limited access...I doubt you'll here from the account again.
