Answer:

Pascal triangle in C

#include <stdio.h>

long factorial(int);

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");

}

return 0;

}

long factorial(int n)

{

int c;

long result = 1;

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

result = result*c;

return result;

}
