Write a C++ programming code to print Pascal Triangle.

Write a C++ programming code to print Pascal Triangle.

Program Code:

#include<iostream>

long fact(int);

int main()

{

int i, n, c;

cout<<"Enter number of rows to print Pascal triangle : ";

cin>>n;

cout<<endl;

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<<endl;

}

return 0;

}

long fact(int n)

{

int c;

long res=1;

for(c=1; c<=n; c++)

{

res = res*c;

}

return (res);

}

The program output is tested on www.jdoodle.com
