what do i do if i don't know the no. of arguments that have to be passed to the function with variable length argument i.e. in the above function what do i do if i want to do away with num completely?

#include<iostream>
#include<cstdarg>
using namespace std;
double avge(int num,...);
int main(){

double x=avge(2,4.0,6.0);
cout<<x<<endl;
}
double avge(int num,...){

is it possible to initialise a char array separately from where it is declared without using either a for loop or initialising the array character by character?

ok. earlier i did not that int(*)(void *,void*) was actually being used for a cast. thankyou.

how is the pointer to a particular function passed in the following code


qsort((void **)lineptr,0,nlines-1,(int(*)(void*,void*))(numeric?numcmp:strcmp));
is it the normal way to pass a pointer...

thank you for your reply. what you sad can be done. but i am trying to understand what that declaration means.

another important observation. when i do the following initialisation the the warning...

in k&r c the following declaration is given to be pointer to array[13] of int

int (*daytab)[13]
on similar lines i initialize a pointer to array[2]of int in my program as follows

int c[2];...
