Hi,

Im running windows xp pro and compiling using dev c++ 4. I have the
following situation:

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

int main() {
    string str;
    func(str);
}

void func(string str) {
    //do stuff, call some other classes member functions etc
    func2(str);
}

void func2(string str) {
    //do more stuff
}

It says 2 errors occur with the following output:

7 errormain.cpp
 implicit declaration of function `int func(...)'
7 errormain.cpp
 warning: cannot pass objects of type `string' through `...'
12 errormain.cpp
 implicit declaration of function `int func2(...)'
12 errormain.cpp
 warning: cannot pass objects of type `string' through `...'

What am I doing wrong???

Thanks for any help in advance
jason
