I am learning C++, so please be kind. Is there anywhere that I can
view the source code for the toUpper function? Thanks.

You can download the standard C library with GCC. Ja********@gmail.com wrote:

There is no "the source". Each implementation is free to write it the
way they want, as long as the behavior is what the standard requires.
For instance, one that uses ASCII might take a peek its current value
and subject a set value if its currently in the "lowercase" range.
Try doing a search for toupper.c to find some implementations.

Never heard of toUpper.
Take a look at ctype.h for a C answer and note that toupper(...)
becomes std::toupper(...) according to <cctype>.

How likely is that to give the OP the source code for the function?

It should, it does here. And since C++ nor C are proprietary, hidden
implementations, if its not found there on his platform, it most
certainly will be found elsewhere.

It does? Where is "here"? I've not seen source code for library
functions in headers in any implementation I've ever used.
And since C++ nor C are proprietary, hidden
implementations, if its not found there on his platform, it most
certainly will be found elsewhere.
Say what? The implementations more certainly are proprietary, and are
often not distributed. Where did you get the idea that it was otherwise?

I said proprietary + hidden as in MFC/ATL etc where the source is
tucked away in object files. The source for toupper as well as the rest
of the C++ language might certainly be copyrighted, but hidden it is
most definitely not. Unless you happen to come accross some
implementation i've not seen.

Well, I use Visual C++, and I don't believe they provide the
implementation. Libraries are the usual method. Some do provide the
source files, which allows the implementation to be built, but it's
certainly not required (and not typically found in headers anyway).

But you can always get it from an open source implementation and since
toupper is pretty trivial and has a fairly limited set of reasonable
implementations it should be pretty close to whatever closed source
version you're using.

Yes, which is what I recommended in the first place. Actually, a search
on the drive holding VC++ finds a TOUPPER.C file, which says:
*Purpose:
* Defines function versions of _toupper() and toupper().
So looks like it does provide at least some source.

I think you get all the source with VS. You need it to view source
when debugging or you just end up stepping off the assembler cliff.

Yep, that's exactly what it does.
Never mind.

Well, here is one *suggestion* which *might* work for you, if you use
ASCII as pointed out by "Default User" <de***********@yahoo.com>:
int toupper(int c)
{
return (c-32*(c>='a' && c<='z'));
}
