Lab 4.1.1 Multi-dimensional arrays of variable length Objectives Familiarize the student with: Scenario creating two-dimensional arrays; accessing two-dimensional arrays; creating variable-length arrays. Write a program that will calculate the average grade of a student and print a summary report. The following rules apply: . a student may sign up for any number of courses; during a course, the student may receive any number of grades; grades are integer numbers in the range [1..5]; the final grade for a course is the arithmetic mean of all grades received during the course; the overall final grade is the arithmetic mean of the final grades received for all the courses the student has taken. All floating-point numbers printed by the program should be limited to two decimal points. The input is given in the following form: C N1 G11 G12.. Gin N2 621 622 62n Ne Gel Ge2.. Gcn Where: C Nx number of courses taken by the student number of grades received during course number x Gabb-th grade received in course number a Example input 3 42345 245 3445 Example output Course 1: final 3.50, grades: 2 3 4 5 Course 2: final 4.50, grades: 4 5 Course 3: final 4.33, grades: 4 3 5 Overall final 4.11
