Pascal Triangle

C program to print Pascal triangle which you might have studied in Binomial Theorem in Mathematics

#include<stdio.h>
#include<conio.h>
long factorial(int);
main()
{
int i, n, c;
clrscr();
printf("\n Enter number of rows in pascal triangle : ");
scanf("%d",&n);
for ( i = 0 ; i < n ; i++ )
{
printf("\n\t");
for ( c = 0 ; c <= ( n - i - 2 ) ; c++ )
printf(" ");
for( c = 0 ; c <= i ; c++ )
printf("%ld ",factorial(i)/(factorial(c)*factorial(i-c)));
}
getch();
}

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