uppercase method

[tricolaire]

I'm using the g++ c++ compiler, and I need a method to convert a string to all uppercase characters. the string class doesn't seem to contain one, at least, not one that I've been able to find. please help!

One method I use:#include <algorithm>
#include <string>
using namespace std;
int main()
{
string s="hello";
transform(s.begin(), s.end(), s.begin(), (int(*)(int)) toupper);
}Another way of doing it is like this:#include <string>
using namespace std;
int main()
{
string s="hello";
for (int j=0; j<s.length(); ++j)
{
s[j]=toupper(s[j]);
}
}HTH,

fair enough, I thank you

but where (what header) does the function toupper come from?

I think it is in iomanip but I could be wrong.

toupper is actually in the STDLIB or CTYPE headers... ;)
