Thread: C++ problem

Hi
if anyone can help me to find out what is wrong with my program
it gives me 3 different errors, which I'm not familier.
Thanks

Code:

#include <iostream>
#include <fstream>
#include <string>
#include <cctype>
using namespace std;

istream& FLUSH(istream& stream);               // Flush function
int lengthcheck(string);                       // Length check function
