string to upper case

[Philip Nicoletti]

std::transform() should work. I have two versions
of g++. On one it works, on another (older) it has
a compiler error.

#include <iostream>
#include <algorithm>
#include <string>

using namespace std;

int main(int argc, char* argv[])
{

    string str = "Hello World";

    transform(str.begin(),str.end(), str.begin() , toupper);

    cout << str << endl;

    return 0;
}
