Subject: g++ question
This list isn't for how to program in C++. This list is for how to
write a compiler.
I was writing some code to test the toupper(ch) library function that
is found in the cctype library.
cctype is not a library. We call those things header files.
I noticed I had not entered the line
#include <cctype>
So, to fix your code, you'd want to add it.
in my C++ program, yet my program compiled and ran correctly as
though I had.
Yes, incorrect programs are allowed to work, even though they are
incorrect.
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.
Run -E and study the output, also -dM might help.
