C++ Pascal Triangle Examples

#include <iostream>

using namespace std;
int main()
{
  int rows,coef=1,space,i,j;
  cout<<"Enter number of rows: ";
  cin>>rows;
  for(i=0;i<rows;i++)
  {
    for(space=1;space<=rows-i;space++)
      cout<<"  ";
    for(j=0;j<=i;j++)
    {
      if (j==0||i==0)
        coef=1;
      else
        coef=coef*(i-j+1)/j;
      cout<<"    "<<coef;
    }
    cout<<endl;
  }
}

Output

Enter number of rows: 6
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
