    Menu structure contains these entries:

    - Create an entry
    - Amend/Delete an entry
    - Search for an entry

    - Quit Application

    Thanks.... any suggestions on how to do this, would be appreciated greatly.....

    What bit are you having trouble with? Post the code you've tried so far, and explain where you're having troubles and someone will help you.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    That's the problem, I want to create a personal Electronic Organiser and I am a raw novice in C Programming. I have been learning Programming for around 3 weeks, I don't know which functions I need to use? Obviously printf and scanf functions, but I don't know how to write this code to do this.... I don't want full help, I just want ideas and maybe small parts of code to assist me....

    Thanks........

    Code:
    /* Warning: This code is from memory and untested */
    #include <stdio.h>
    
    int menu ( void );
    void create_entry ( void ) { puts ( "create entry" ); }
    void update_entry ( void ) { puts ( "update/delete entry" ); }
    void search_entry ( void ) { puts ( "search entry" ); }
    void create_transfer ( void ) { puts ( "create transfer file" ); }
    
    int main ( void )
    {
      void (*jump_menu[4]) ( void ) = {
        create_entry,
        update_entry,
        search_entry,
        create_transfer,
      };
      int option;
    
      while ( ( option = menu() ) != 5 ) {
        if ( option < 1 || option >= 5 ) {
          printf ( "Blah, bad choice\n" );
        }
        else {
          jump_menu[option - 1]();
        }
      }
    
      return 0;
    }
    
    int menu ( void )
    {
      int option;
    
      printf ( "1) Create an entry\n"
               "2) Amend/Delete an entry\n"
               "3) Search for an entry\n"
               "4) Create mobile phone transfer file\n"
               "5) Quit Application\n"
               ":> ");
      scanf ( "%d", &option );
    
      return option;
    }
    Or you could search the boards. This question is asked at least once a week.
    My best code is written with the delete key.

    Function pointer arrays, you meany?! Sorry, got to highlight that one But hopefully Socrates will get the jist of what's going on...

    The jist being to search the boards for more suitable code.
