Function Overloading or Polymorphic Behaviour for C
functions can be seen for those functions who accept
variable number of arguments.
They can take any number of arguments and any type of
arguments, its upon the programmer or the code inside it,
that decides what it wants those arguments to be , int ,
char ,float or something else..

ALthough it is not seperate function that runs for different
number and types of arguments, still for the user, a
function will be provided for different types of list of
input parameters, all being sent to the same ('name of the
')function..

#include <stdarg.h>
enum data_type{ TYPE_INT=0,TYPE_STRING=1};
int max( int num_of_arguments,...)
{
va_list arg_list;
va_start(arg_list, num_of_arguments);
data_type type=va_arg(arg_list,data_type);

if(type=TYPE_INT)
{
int max =0,i;
for(i = 2; i <= num_of_arguments; i++)
{
if((a = va_arg(arg_list, int)) > max)
max = a;
}
}
else
{
//do whaterver..
}
va_end(arg_list);

}

In this problem you are to write a program that will cut some number of prime numbers from the list of prime numbers between 1 and N.Your program will read in a number N; determine the list of prime numbers between 1 and N; and print the C*2 prime numbers from the center of the list if there are an even number of prime numbers or (C*2)-1 prime numbers from the center of the list if there are an odd number of prime numbers in the list.
