Pascal Traingle

#include<stdio.h>
#include<conio.h>

long factorial(int);

void main()
{
    int i,n,c;
    printf("Enter the number of rows::\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();
}

long factorial(int n)
{
    int c;
    long result = 1;
    for(c=1;c<=n;c++)
    result=result*c;
    return(result);
}

Output of program:
Pascal triangle
