The formula for combination is ncr = n!/(r!*(n-r)!)
#include"stdio.h"
#include"conio.h"
int main()
{
long int fact(int);
int i,j,a,val;
printf("Pascal Triangle");
printf("\n Enter How many lines needed : ");
scanf("%d",&a);
for(i=0;i<=a;i++)
{
for(j=0;j<=i;j++)
{
val = fact(i)/(fact(j)*fact(i-j));
printf("%d\t",val);
}
printf("\n");
}
return 1;
}
long int fact(int n)
{
long int fa;
if(n==0)
return 1L;
else
fa = n * fact(n-1);
return fa;
}
