a.Write a program to input the following integer numbers in an array named grades:89,95,72,83,99,54,86,75,92,73,79,75,82, and 73. As each number is input, add the numbers to a total. After all numbers are input and the total is obtained, calculate the average of the numbers, and use the average to determine the deviation of each value from the average. Store each deviation in an array named deviation. Each deviation is obtained as the element value less the average of all the data. Have your program display each deviation with its corresponding element from the grades array. b. Calculate the variance of the data used in Exercise 9a. The variance is obtained by squaring each deviation and dividing the sum of the squared deviations by the number of deviations.
