3. Given the following struct declaration for a student, complete the subroutine which (a) calculates each student's grade as P'or 'F' depending on whether the score is higher than or equal to 75, and (b) returns the average class score. Test your program using KeiluVision. Capture screen shots to demonstrate the correct execution of your code #define SIZE 64 struct Student f unsigned long id; unsigned long score; unsigned char grade; II you will enter '' or 'F" li typedef struct Student STyp unsigned long Grades (Styp class[SIZE]) // write the code to implement the functionality of this subroutine
