    Post Sorting exam score in increasing order

    Hello, I'm a first year university student that has just started learning C language. Right now, I'm trying to learn the section on "Sorting" and found this program online, which generates ramdom student names and scores, and sort the scores out in increasing order. As indicated on the attached program (sort.c), I want to make the labled section as a separate function outside of the main function i.e. sort_mod.c <---not working

    Could someone teach me how would I go about doing this? Thanx in advance!

    Best regards, superman

    That code doesn't free the malloc()ed memory. You should free it.

    First of all, you should put in a prototype for your function.

    Code:
    void mysort(int group[].point,SIZE)
    SIZE has to have a type, like int SIZE. Unless you're referring to the #define SIZE. In that case you don't need to pass it as an argument at all.
    Code:
    void mysort(struct student group[])
    And when you call your function (from main()), you would do it like this:
    Code:
    mysort(group);
    Read up on structs and functions.

    I modified the program and compiled with GCC, and now it gives me the following errors!

    sort_mod.c:14: error: syntax error before '.' token
    sort_mod.c: In function `mysort':
    sort_mod.c:27: error: incompatible types in assignment
    sort_mod.c:27: error: incompatible types in assignment

    Could someone tell me what's wrong with the program?? Thanx in advance!

    The prototype for mysort is still wrong, make it more like:
    void mysort(struct student group[]);

    The w variable within mysort should be the same type that you wish to swap around:
    struct student w;
    (not int w;)
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
