I added this function: void continueOrExit(int choice, int numOfTestScores, int numOfStudents); // choose contnite or exit The user is who decides to finish or continue the program but I have errors. please correct it.

/* Write a program that uses a structure to store the following data: Name - Student name, Idnum - Student ID number, Tests - Pointer to an Array of test scores, Average - Average test score, Grade - Course grade 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 Tests 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 of each student. The average test score should be calculated and stored in the average member of each structure. The course grade should be computer on the basis of the following grading scale: 91-100 = A, 81-90 = B, 71-80 = C, 61-70 = D, 60 of below is 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 student'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 negative numbers for any test score. */
