How to achieve function overloading in C?

Question

Is there any way to achieve function overloading in C? I am looking at simple functions to be overloaded like

foo (int a)  
foo (char b)  
foo (float c , i         


        

Answer 1

I hope the below code will help you to understand function overloading

#include 
#include

int fun(int a, ...);
int main(int argc, char *argv[]){
   fun(1,10);
   fun(2,"cquestionbank");
   return 0;
}
int fun(int a, ...){
  va_list vl;
  va_start(vl,a);

  if(a==1)
      printf("%d",va_arg(vl,int));
   else
      printf("\n%s",va_arg(vl,char *));
}
