C and C++ Program to Display Pascal's Triangle

This post gives C and C++ programs to display given number of rows of pascal's triangle. Thenuser can enter the number of rows of pascal triangle to be displayed.

C Program:

#include<stdio.h>

#include<conio.h>

long factorial(int);

main()

{

int i, n, c;

printf("Enter the number of rows you wish to see in pascal triangle\n");

scanf("%d", &n);

for (i = 0; i < n; i++)

{

for (c = 0; c <= (n - i - 2); c++)

printf(" ");

for (c = 0; c <= i; c++)

printf("%ld ", factorial(i) / (factorial(c) * factorial(i - c)));

printf("\n");

}

getch();

}
