Print Pascal Triangle in C++

To print pascal triangle in C++ programming, you have to ask to the user to enter the number of line (upto which he/she want to print pascal triangle).

So to print pascal triangle, you have to use three for loops as shown here in the following program.

C++ Programming Code to Print Pascal Triangle

Following C++ program ask to the user to enter number of line or row upto which the Pascal triangle

will be printed to print the Pascal triangle and display it on the screen:

#include <iostream>

using namespace std;

int main()
{
//
int i, n, c;
//
long fact(int n);
cout<<"Upto how many line (Enter number of rows) : ";
cin>>n;
//
for(i=0; i<n; i++)
{
//
for(c=0; c<=(n-i-2); c++)
{
cout<<" ";
}
//
for(c=0; c<=i; c++)
{
cout<<fact(i)/(fact(c)*fact(i-c));
cout<<" ";
}
cout<<"\n";
}
return 0;
}
