C program to print pascal triangle

Pascal's triangle is a triangular array of the binomial coefficients. In much of the Western world it is named after French mathematician Blaise Pascal.
 

#include<stdio.h>
int main()
{
   int i,j,l,binom;
   printf("enter the no of lines=");
   scanf("%d",&l);
   for(i=1;i<=l;i++)
   {
       for(j=1;j<=l-i;j++)
           printf(" ");

        binom=1;
       for(j=1;j<=i;j++)
    {
                 printf("%d ",binom);
                 if(i==j+1)
    binom=1;
            else
binom=(binom*(i-j))/j;
}

           printf("\n");
}
return 0;
}  

OUTPUT-
enter the no of lines=6
          1
         1 1
        1 2 1
      1 3 3 1
    1 4 6 4 1
 1 5 10 10 5 1
