12. Course Grade Write a program that uses a structure to store the following data: Member Name Description Name Student name Idnum Student ID number Tests Pointer to an array of test scores Average Average test score Grade Course grade 662 Chapter 11 Structured Data The program should keep a list of test scores for a group of students. It should ask the user how many test scores there are to be and how many students there are. It should then dynamically allocate an array of structures. Each structure's Tosts member should point to a dynamically allocated array that will hold the test scores. After the arrays have been dynamically allocated, the program should ask for the ID number and all the test scores for cach student. The average test score should be cal- culated and stored in the average member of each structure. The course grade should be computed on the basis of the following grading scale! Average Test Grade Course Grade 91-100 81-90 B 71-80 61-70 D 60 or below F The course grade should then be stored in the Grade member of each structure. Once all this data is calculated, a table should be displayed on the screen listing each stu- dent's name, ID number, average test score, and course grade. Input Validation: Be sure all the data for each student is entered. Do not accept nega- tive numbers for any test score
