    Challenging Logic

    Hi,
    I am new to c language and i have a problem to solve. Imagine a
    parent child relationship let me take menu as an example

    File Edit
    New Cut
    Window Copy
    Message
    Open

    here File and Edit are Top Level Parents(root menu), New and Open are
    children of File. Window and MEssage are children of NEw. Similarly
    Cut and Copy are children of Edit.

    I can have only 2 functions like Next and GetSubMenu. Initially i will
    display File when i say next it should show me edit when i say next it
    should show me file.

    When i am in File when is say get submenu it should display new and
    now next should give me open and next should take me to File since
    Open is the last child of File. Similary when i am in New and say
    GetSubMenu it should give me Window and Next should give me Message
    and Next should give me New.

    I dont know whether i need to use a bidirectional circular linked list
    or array. i need some help from you.

    Thanks.

      Hello Nash,

      Below is a similar data structure that accounts your problem ...

      typedef struct my_menu
      {
      char * menu_name;
      struct my_menu * next_menu;
      sturct my_menu * child_menu;
      }my_menu;

      The 'struct my_menu * next_menu' pointer should point to the next
      menu item, e.g. File>Edit
      The 'struct my_menu * child_menu' pointer should point to the child
      menu item, e.g. File>New>Window

      I hope this helps you :)

      Thanks
      Akbar

          Hello Nash,

          Below structure should solve your problem,

          typedef struct my_menu
          {
          char * my_menu_name;
          struct my_menu * child_menu;
          struct my_menu * next_menu;
          }my_menu;

          the 'child_menu' pointer shall point to child menu items, e.g.
          File>New menu item
          the 'next_menu' pointer shall point the next parent menu item e.g.
          File>Edit

          I hope this helps :)

          Thanks
          Akbar
