Some people need to be shot ! This is not C or C++ code, it is C code and
considered very bad C++ code. No wonder that C++ get so much bad press with
such slander.

The *real* C++ version :

#include <list>
#include <string>
#include <algorithm>

using namespace std;

bool guest(string m, list<string> l)
{
    return find(l.begin(),l.end(),m) != l.end();
}

// And now the testing code

#include <iostream>

void try_find(string m, list<string> l)
{
    if(guest(m,l))
        cout << "Found   " << m << '\n';
    else
        cout << "Missing " << m << '\n';
}

int main()
{
    list<string> l;
    l.push_back("Hi");
    l.push_back("There");
    l.push_back("You");

    try_find("Hi",l);
    try_find("Yes",l);
    try_find("You",l);
}
