Hi,
Ok, what's the deal with the following code? I expected the third
use of toupper() to work, but when compiled, I get the complaint below
(the prog). Should the call to unqualified toupper() work? or is this
another "I've much more to learn" situation ;)
thanks.
Brent
#include <iostream>
using namespace std;
int
main(){
char a('a');
cout.put(std::toupper(a)); // ok
cout.put(::toupper(a)); // ok
cout.put(toupper(a)); // causes the output below
return 0;
}
speedy$ g++ -g -Wall -I. toupper.cc -o toupper
