using c++ programming

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 Nscores and totals. Calculate the overall percentage (sum of the total points earned divided by the total points possible) and output it as a percentage. Sample input and output is 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%
