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);

}

There is a 100-story building and you are given two eggs. The eggs (and the building) have an interesting property that if you throw the egg from a floor number less than X, it will not break. And it will always brake if the floor number is equal or greater than X. Assuming that you can reuse the eggs which didn't broke; you got to find X in a minimal number of throws. Give an algorithm to find X in minimal number of throws.
