Subject: g++ question
To whom it may concern,
I'm currently using the following version of g++
g++ (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8)
I was writing some code to test the toupper(ch) library function that
is found in the cctype library.
I noticed I had not entered the line
#include <cctype>
in my C++ program, yet my program compiled and ran correctly as though I had.
**********************
I've included the source file as an attachment to this email, and here is the
output of the program:
% a.out
temp = h
To upper conversion: H
*********************
Why did this work - all the C++ books I've read state that you need to
include the cctype library if you want to use the toupper(..) function.
Also, is there any documentation on this matter. (I've look around the GNU site
and am at a loss as to where to look/find this type of information)
Kind regards
serge
#include<iostream>
using namespace std;
int main()
{
char temp = 'h';
cout << "temp = " << temp << endl;
cout << "To upper conversion: " << char(toupper(temp)) << endl;
return 0;
}
