Use the % operator in the SWITCH statement. You know what values you will get so use those values in the CASE statements.

Please don't be so pushy. this statement is completely unnecessary and can be read as rude. Just so you know.

can you please write the code

[WaltP]

Yes I can.

If you want me to do it for you, as a computer consultant I get $85 an hour.

Walt, note that I am not the OP. I am getting tempted to send you a check for $85.

I cannot see how use the modulo operator is going to help much with determining whether a number is positive or not in a switch statement. This seems like an obvious case where an if statement make sense and a switch statement does not. What am I missing?

I would use abs() (from math.h) inside the switch statement (assuming you're dealing only with integers).

Why not just use if?

int a;

if( a > 0 )
{
 positive
}else if( a < 0)
{
 negative
}

If the exercise is to actually use a switch statement, the actions you take are different.

When I get home, I'll write the code for you.

This isn't rocket science guys...

int i = -1;

bool IsPositive()
{
	if(i > 0)
		return true;
	else if(i < 0)
		return false;
}

void Example()
{
	switch(IsPositive())
	{
	case true:
		cout << "+" << endl;
	break;
	case false:
		cout << "-" << endl;
	break;
	case default:
		cout << "Zero/Unknown?" << endl;
	break;
	}
}

Oops, made a tiny error.. fixed:

int i = -1;

bool IsPositive()
{
	if(i > 0)
		return true;
	else if(i < 0)
		return false;
}

void Example()
{
	switch(IsPositive())
	{
	case true:
		cout << "+" << endl;
	break;
	case false:
		cout << "-" << endl;
	break;
	default:
		cout << "Zero/Unknown?" << endl;
	break;
	}
}
