Hello Jose!

I tried your code (after storing it in 3 different files) with Dev C++. I 
made a project and asked the IDE to compile it: everything seemed fine (no 
compilation errors), but when I tried to execute it ... I had troubles! :-)

Unlike me, you had some compilation error, I guess it is because you turned 
on some extra warnings, while I used only the "plain" Dev C++ options.

When I tried to compile your program from the command line (see the file 
main.mk) I got these kind of errors:
- main should return an integer
- you are passing a "const char *" where a "char *" is expected

Maybe the second kind of error needs some comment.
Your prototype says: "extern char* LCase(char *str);" (by the way the 
"extern" is not necessary), so a "char *" is expected. In your test 
program, when you call the function by the line: "LCase("This is a test of 
LCase\n");", you are handing it a "const char *" (a "string constant" to be 
more specific). Usually compilers store string constants in a sort of read 
only memory, so when you attempt to modify them you'll get (at least) a run 
time error.

I suggest that you modify main.cpp in this way:
- build a "char *" using a constant string, and use hand it to your functions

I've changed your main.cpp according to the above, I also used "C style 
strings". Since you are using C++ I suggest you use "C++ style strings" 
(see your documentation on the standard library).


Hope this helps.
