Write code in C++

Q: Submit the code that gets 4 student names and 6 grades (2D array, for example, columns are 1: Math, 2: CMPS191, 3: CMPS 201, 4: CMPS190, 5: CMPS 300, 6: CMPS 291) for each student from the keyboard. [So far, you have the code as explained in the class]. After recording the grades and names in the arrays, (1) find the average grades of each student (so, you need to define a new array with the same length as the number of students), (2) find the average grades of each course (so, you need to define a new array with the same length as the number of courses), and (3) find the average grades of all 4 students in all 6 courses, which will be a single number. Display all the results on the screen when the user has done with entering the last grade.
