    Setting a user's input as the structure name

    Hi there, i am looking for some help in structures.

    I am not sure if i am going about this the right way but i am looking to use structures to store multipul details of one panel.

    How does the basic struct work?

    for instance, if the structure is:
    Code:
    struct panel
     {
       char name[25];
       int age;
       float cost;
     };
    how do i add an additional panel and then how do i recall specific infomation about this panel?

    i am worried about having to have:

    Code:
    struct panel1
     {
       char name[25];
       int age;
       float cost;
     };
    
    struct panel2
     {
       char name[25];
       int age;
       float cost;
     };
    etc...

    and only being able to have a finite number of panels.

    I am I am missing something basic here, but could someone explain for me?

    also i intend to store the info in a data file so when the user re-opens the program, (s)he is able to say load panel, and the program lists the previously saved panels, allowing the specific panel's details to be loaded for editing.

    Any help would be awesome

    Ste

    structs are blueprints; you must create them first. Thus, you can create an almost infinite amount of structs from the blueprint. You don't need several structs with the same data.

    To me, it sounds like you actually want to store the users input as a filename, and restore it based on what name the user gives.

    Code:
    struct panel
     {
       char name[25];
       int age;
       float cost;
     };
    
    panel many_panels[10000];
