[Dondolo M. <MDo...@OL...>]

Hi all,

I am wiggling my way around C++ currently, I am not doing a bad job at all.
(Well at least I think)...I am trying to write a simple telephone directory
system that will store all my buddies contact details. I intend on storing
their info in separate functions. for example:
                                                        void
MarkContact(void)
                   				{
						//Marks contact details
                                                            }

				and so on.....

I want to be able to open the program, enter someone's name and get their
stored details. The problem I get is when evaluating my input, I get
errors....c++ permits me to evaluate a single character but not string of
characters.

e.g.
                                 /*

			all include files			
                                    and declarations

                           */
                   cout<<"Please enter a persons name";
                    cin<<Name;
              switch(Name)
                        {
                        case   Mark:                      
                                          MarkContact();
                                         break;
//the rest of the program

can someone please help me or advise me of any other method.........
Thanks guys

----------------------------

Strings are actually arrays (which are actually pointers). So if you're
comparing these (remember that strings have to be put in quotes):

    char my_name[] = "Abhijit";
    char your_name[] = "Dondolo";

you would actually be comparing the pointers. You need to compare each
character. There is already a library function called strcmp(), which
compares them.

strcmp(first, second)

returns > 0 if first > second
        < 0 if first < second
        = 0 if first == second.

stricmp() is the case-insensitive version.

They're defined in <cstring>, and to access them, you would use the using
declaration:

using std::strcmp;
using std::stricmp; // Whichever

in the scope in which you want to use it (within the function, global,
etc.).

So I would say,

    if(stricmp(my_name, your_name) == 0)
        cout << "Hey, you're me!\n";

All this should have been written in the book you use (I assume you use a
book). If you don't have one, I suggest you get yourself a trustworthy book.
Post on this list for more info. Ioannis mentioned http://www.accu.org/ as a
site for reviews. I haven't seen it myself, I'm just recycling posts. Saving
the (integrated development) environment (mailing-list) and stuff...

PS: It should be cin >> name, not <<. I think that was a typo.

HTH.
And, yeah... Wish y'all a Happy New Year 2003.

[Per W. <pw...@ia...>]

Just a note.

On some systems, the case-insensitive function is named strcasecmp instead
of stricmp.

That's one of the reasons why people gets compile errors when trying to
build wxWindows  applications without using a correct project that defines
what target to build for.
