need some help in a program

This is an optional solution:

#include <iostream>
using namespace std;

int main()
{
int row;
int startrow;
int num;
int counter;

cout << "Give the number of rows of the pyramid:" << endl;
cin >> row;

counter = 1;
for(startrow = row; row>0;--row)
{
//Drawing blancs
for(num=startrow-counter;num>0;num--)
{
cout << " " ;
}

//Drawing stars
for(num=(counter*2)-1; num > 0;num--)
{
cout << "*";
}

cout << endl;
counter++;
}

return 0;
}

Hope this helps.
