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(); }
