in C++

For the assignment, we will write a program that calculates the total grade for N classroom
exercises as a percentage. The user should input the value for N followed by each of the N
scores and totals.
Calculate the overall percentage (sum of the total points earned divided by the total points
possible) and output it as a percentage. Then determine the letter grade using the following
scale:
A: 93%-100% ; A-: 90%-92.99% ; B+: 87%-89.99% ; B: 83%-86.99%; B-: 80%-
82.99%; C+: 77%-79.99%; C: 73%-76.99%; C-: 70%-72.99%; D+: 67%-69.99%; D:
63%-66.99%; D-: 60%-62.99%; F: Less than 60%.
Match your program with the sample input and output as shown below.
How many exercises to input? 3
Score received for exercise 1: 10
Total points possible for exercise 1: 10
Score received for exercise 2: 7
Total points possible for exercise 2: 12
Score received for exercise 3: 5
Total points possible for exercise 3: 8

Your total is 22 out of 30, or 73.33%.
Your letter grade is C.
