C++ please

1. Write a program that prompts the user to enter five test grades. Store each test grade in an array. After the grades are entered, use a for loop to compute the sum and then compute the average grade from the sum.

2. Modify problem 1 so that you also have a second array of strings that stores the student's names. This array should parallel the grade array so that the first student's name is in position 0 of the names array and their test score is in position 0 of the grades array, and continue this for the rest of the students. Write a for loop that displays each student's name along with their grade.

3. Write a program that takes the grades entered in Problem 1 and displays the grades in reverse order.

4. Using random number generation, write a program that stores 100 values from 1 to 100 in an array. Display the array to the user. Prompt the user to enter a value that occurs in the array and then have the program count the number of times the value is found in the array. Display the final count.
