Question

Write a program using c++ that:

includes a function that reads integers consisting of students’ test scores in the range of 0-200 from a file into a one-dimensional array of size 30
includes a function to calculate the mean (add all the scores and divide by the number of scores)
includes a function to calculate the median (sort the scores and then find the score in the middle—if there is an odd number of scores, the median is the middle score; otherwise, it is the average of the two middle scores)
includes a function to calculate the mode (most frequently occurring score)
includes a function to calculate the standard deviation
includes a function to determine the number of students having scores in each of the following ranges: 0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174, 175-200 and output each score range followed by the number of students within that range
includes a function to print everything to an output file

Clearly identify all output. Do not use global variables. Your main function should consist primarily of function calls.

Use the following data:

76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189
