STL lists

Compiled the code on g++ and it won't work, why?

Code:

---

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

void func(string t) {
    cout << t << endl;
}

int main() {
    list < string > prod_code;
    string temp;
    do {
 cout << "Enter Product Code: ";
 if (cin >> temp) {
    prod_code.push_back(temp);
 } else {
    break;
 }
    } while (1);

    sort( prod_code.begin(), prod_code.end() );
    for_each(prod_code.begin(), prod_code.end() , func);
    return 0;
}

The compile won't work..? Least, I couldn't get it to go, but I modfied it a bit and it was all working fine.

Code:

---



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

void func(string t) {
    cout << t << endl;
}

int main() {
    list < string > prod_code;
    string temp;
    do {
 cout << "Enter Product Code: ";
 if (cin >> temp) {
    // couldn't figure out how to make cin >> temp fail without exitting program :(
    if (temp != "stop")    prod_code.push_back(temp);
    else break;
 } else {
    break;
 }
    } while (1);

    // sort( prod_code.begin(), prod_code.end() );  // didn't compile with gcc 2.9.5 or 3.0.4
    // list's have their own special sort (std::uglyAndHackish :( ) because they don't have random access iterators
    // which makes the default (usual quicksort) simply no longer quick :).
    prod_code.sort();
    for_each(prod_code.begin(), prod_code.end() , func);
    return 0;
}

Thanks heaps for your help, greatly appreciated. I compiled the code and it works. Thank you.
