about toupper()

Hello, I'm wondering if there is a library with a toupper() kind of function that can handle string insted of char?

Code:

---

#include <iostream>
#include <ctype.h>
using namespace std;

void toUpperCase(char*);

int main() {
    char str[80];
   
    cout << "Enter something: ";
    cin.getline(str, 80);
   
    toUpperCase(str);
   
    cin.get();
    return 0;
}


void toUpperCase(char* s) {
    int count;
    while(*s) {
        *s = toupper(*s);
        s++;
        count++;
    }
    s -= count;
    cout << s;
}

---

this is what I've got now, but I want to use string instead

as I remember it I could use ASCI values of the upper case letters to convert, but that's sounds tiresome. Why reinvent something that maybe already exists, right?

Indeed there is: boost string algorithms which includes algorithms for case conversion.

std::transform() for a one liner conversion.

Thanks for the help :)
