Hello daniweb people! I'm having a few issues with this triangle program. We're supposed to make a few different triangle shapes, including the two i have in this. The first triangle works, but the second triangle displays xxxxxxxxxxxxxxx times infinity. Any ideas on what i'm doing wrong? And another question, how would I get started with part of this program to also make a diamond shape given a certain Row size input? thanks!

#include <iostream>
#include <math.h>
#include <string.h>
using namespace std;
int main()
{
// make triangle 
// X
// XX
// XXX
// XXXX
// XXXXX
// XXXXXX
int rowSize;
cout << "Please enter the number of rows between 3 and 6 for a triangle: ";
cin >> rowSize;
for (int r=0;r<rowSize;r++)
{
	for(int c=0;c<r+1;c++)
	{
		cout << "*";
	}
	cout << endl;
}


{ 
	// Make triangle shaped different like so:
	// ******
	// *****
	// ****
	// ***
	// **
	// *
	int rowSize;
	cout << "Please enter another row size for a different triangle: ";
	cin  >> rowSize;
	for (int r=0;r<rowSize;r++)
	{
	for (int c=0;c<r-1;c--)
	{
		cout << "*";
	}
	cout << endl;
	}
	system("pause");
return 0;
}
}

but the second triangle displays xxxxxxxxxxxxxxx times infinity.

if you have infinity in looping in your source code, then you should check
termination conditions in your code.

for (int c=0;c<r-1;c--)

so check this termination condition.

when r=0 it terminates.
when r=1 it terminates.
when r=2 it does not terminate......
