    Hi,
    I have a problem with sturcts.
    I have something like :
    Code:
    struct stack1 
    {
       int number;
       struct stack1 *next;
    };
    
    I want to create structs as user request.
    I mean, i`ll get some number from the user input, and create this number of startcts.
    For example, i got the number 3 from the user.
    Automaticly create :
    stack1 s1; stack1 s2; stack1 s3; ( 3 structs ).
    I dont care the structs names.
    I hope the explanation was clear, Thanks for helpers.
    Or.

    Arrays are your friend, and malloc.
    Code:
    int i=5; // or get this from the user
    struct stack1 *ptr=(struct stack1 *)malloc(sizeof(struct stack1)*i);
    // do whatever you want with ptr, e.g.
    ptr[3].number=5; // which sets the array's *4th* entry number to 5.
    // and DO NOT EVER FORGET:
    free(ptr);
