dont work right
help :(

[David W]

What is this:

using namespace std;

struct karmand{
    char nam[10];
    char shomare[10];
    char sx[10];
    char mm[10];
    char rgh[10];
    }list[s]; /*  s = ??? */

Don't you mean to code:

struct Contact
{
    // your contact info gets saved here
} ;

const int MAX_SIZE = 100;

Contact MyContacts[MAX_SIZE];

Your code seems to be C code (except for the 'using namespace std;' line ... maybe best to re-post as all C code in the C forum?

Also, do not use conio (cls, getch, etc) if you want portable code.

Best to always avoid dangerous use of gets.

In C++ use getline and a C++ string ...

In C use fgets
( or my fixedFgets
or my C emulation of C++ getline, called readLine )
(free for asking)

Also ...

What does NOT work right?

(What is your code supposed to do?
vs
What does it presently do?)

Does it compile error free?
(If not, please supply error messages.)
