binomial coefficient c code

 #include<stdio.h>  
   
 //binomial coefficient function  
 double Ni(  
         int deg,    //degree   
         int b       //for binomial  
         )  
 {  
     if( deg < 0 )  
         return 0.0;  
     else if ( deg == 0 )  
         return 1.0;  
     else{  
         double temp = 1.0;  
         for(int i=1; i<=b;i++ ){  
             temp = temp* (double)(deg-i+1)/i;  
             printf("%f\n", temp);  
         }  
         return temp;  
     }  
 }  
   
   
 void main ()

     printf("\n=============\n");  
     printf("%f\n", bin);
