I really need some help ASAP!! please please (C LANGUAGE ONLY!!!) in regards to dynamic memory allocation

Problem: A school offers certain number of courses. A course can have one or more sections. A section can have one or more students (assume that a student cannot enroll in multiple sections of the same course). A student has to do a certain number of assignments in the course. In order to pass the course, the average score of the assignment has to be >=70.

Code should implement at least the following functions: a. course *read_courses(FILE *fp, int *num_courses): This function takes a file pointer and reference of an integer to track how may courses the file has. Then it reads the data for an entire test case and return the allocated memory for all the courses (including sections) for a test case. Note that you can call other functions from this function as needed. b. student **read_sections(FILE *fp, int num_students[], int num_scores[], int num_sections): This function takes the file pointer, references of two arrays, one for number of students, and one for number of scores for a course. The function also takes an integer that indicates the number of sections the course has. The function reads all the data for all the sections of a course, fill-up the num_students and num_scores array of the course and returns 2D array of students that contains all the data for all the sections of a course. A good idea would be calling this function from the read_course function. c. void process_courses(course *courses, int num_courses): This function takes the array of courses produced and filled by all the courses of a test case and also takes the size of the array. Then it displays the required data in the same format discussed in the sample output. You can write and use more functions in this process as you wish. d. void release_courses( course *courses, int num_courses): This function takes the array of courses produced and filled by all the courses of a test case and also takes the size of the array. Then it free up all the memory allocated within it. You can create more function as needed to ease the process Structure: typedef struct student{ int id; char *lname; float *scores; //stores scores of the student. Size is taken from num_scores array.float std_avg; //average score of the student (to be calculated) }student; typedef struct course{ char *course_name; int num_sections; student **sections;//stores array of student arrays(2D array). Size is num_sections; int *num_students;//stores array of number of students in each section. Size is num_sections; int *num_scores; //stores array of number of assignments in each section. Size is num_sections; } course;
