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.

Carry out the following task with an array: a. Allocate an arraya of ten integers. b. Put the number 17 as the initial element of the array. c. Put the number 29 as the last element of the array. d. Fill the remaining elements with –1. e. Add 1 to each element of the array.f. Print all elements of the array, one per line. g. Print all elements of the array in a single line, separated by commas.h. Count how many elements are less than a given value (entered by user). i. Remove all elements that are less than a given value (entered by user). j. Place all elements that are less than a given value (provided by user) in another array.

The following program is supposed to let the end-user enters 10 numbers in a one dimensional array. The program must then check the input numbers in the following order and way: 1f the input number is a negative one, the program should multiply that number by (5), and return the number of negative elements in the array. 2. if the input number is a positive one, the program should multiply that number by (2), and return the number of positive elements in the array. 3. if the input number is a zero, the program should return the number of zeros in the array The program code is given below with some missing code. You are required to write the missing code ONLY in order to make the program complete. Sample Input/Output Enter 10 numbers in the array -8 -16 16 80 2 12 -12 -2 0 -40 -80 32 16 0 4 24 -60 -10 0 The number of negative elements is: 4 The number of positive elements is: 4 The number of zeros is: 2 dinclude using namespace std; int main() int input[10], i, negative-0, positive-0,…

1. declare an array to hold 12 floating point numbers:   2. Now that we have our array, set all 12 numbers to -100.   3. Change all even positions (all lines with an even index: 0,2,4, etc) to 96.8Use a function call to print the array.
