Assignment \#7 Description Write the necessary program in C++ that does the following: 1. Declares a whole number type constant value space called MAX_ITEMS and Stores the value of 6 2. Declares a string type of variable firstName to store the first name of a student 3. Declares a Decimal number type of variable spaces called testScore, total (initialize to zero), average 4. Declares a string type of variable called letterGrade Assignment \#7 Description (continued...) 1. Asks (prompts) the user to input a person's name by using the prompt "Enter a name: "on the screen, for example: 2. after user entered the input, for example, Carson: 3. Reads the user's inputted name from the keyboard and Stores it in the array variable created for user firstName Assignment \#7 Description (continued...) 4. Using a for repetition structure that runs MAX_ITEMS number of times, a) Asks (prompts) the user to input that person's test score by name using the prompt "Enter 's test score : " on the screen, for example: Enter Carson's score for test \# 1: b) Reads the inputted score and stores it in the testscore variable space c) Adds the testScore to the total d) Repeats getting all the MAX_ITEMS number of scores Assignment \#7 Description (continued...) 5. After finding the total in the loop, calculate the average and store it in the average space 6. using an if..else structure: a) Uses the average and finds the letter grade for the student and stores it in the letterGrade variable space b) Use this grading scale: 7. Displays the name of the student then the total, average and letter grade of that student: For example
