RE: [Dev-C++] Sentences in a array

Yes, it works, but char* is not a very good thing to use any more. It
creates arbitrary limits on lengths that lead to bugs and security problems.
On top of this, you get a minimal performance increase because C++ compilers
and compiler optimization are a great deal better than they used to be not
long ago.

The whole point of C++ is avoiding these issues with generic programming and
classes. Best of all the performance hit is minimal. If you look at
basically every other language in use today besides C, strings are handled
automatically.

GAWK, perl, C++, etc. all do it using string types.

Sometimes it's not good enough for it just to work. There are other factors
to consider.

The program works fine once you use what comes with Dev C++ and not 
substitued the headings.  I just clipped the code and used the console 
settings and it worked perfectly.  Now I'm not sure what he wants it to do 
but it gave me no problems at all.
