Always post your code in code tags, read the forum announcements for more details.
As far as the problem is concerned, dont know what exactly are you trying to achieve here. You are struggling with your syntax. Here, I will give you a prototype of how your program should look like:
#include <iostream> // .h format of header declaration is depreceated
using namespace std ; // use this new way of declaring headers
void xcopy( char* destination, const char* source )
//your function here
int main( ) // the correct way of using main( )
// declare and initialize variables
// accept input from user
// call the function
// display the result
Just to let you know that you have forgot the closing brace of your function and are getting your syntax all wrong.
