Malloc the struct

Well I have the struct here, an array of structs actually. I have to malloc it, and then free. How is it done, in codes? Thanks for any help. I'm driven crazy for days but I can't do it.

Code:

---

struct Student
    {
    char id[20], grade;
    int *tests;
    int total;
    };

    struct Student Stud[81];

---

Put the struct prototype, before main() (global space), and include the header file, stdlib.h.

Do you want to malloc the int's for tests?

Code:

---

Stud[i].test = malloc(Number of Test int's you want * sizeof(int));

---

should do it.

Yes, I wanted to malloc them. Thanks for the code!
