#include<iostream>
using namespace std;
int main(){
	int r,col=1,b,x,n;
    cout << "\n\n Outputing Pascal's triangle:\n";
  
    cout << " Enter number of rows: ";
    cin >> r;
    for(x=0;x<r;x++)
    {
        for(b=1;b<=r-x;b++)
        cout<<"  ";
        for(n=0;n<=x;n++)
        {
            if (n==0||x==0)
                col=1;
            else
               col=col*(x-n+1)/n;
            cout<<col<<"   ";
        }
        cout<<endl;
