String to Uppercase

[The Hobo]

How can I make sure a <string> is in all uppercase? I've found ways for char strings, but not <string> strings.

[The Hobo]

is there any way to make them all uppercase?

#include <algorithm>
#include <string>
#include <locale>
#include <functional>
//...
std::string s;
if (std::find_if(s.begin(),s.end(),std::bind2nd(std::islower<char>,std::locale::clasic()))==s.end())
    // all uppercase
else
    // some lowercase

This should work

Sorry, I found a mistake in my code.

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

using namespace std;

int main() {
    string s = "Hello world!";
    transform(s.begin(), s.end(), s.begin(), (int(*)(int)) toupper);
    cout << s << endl;
}
