The University wantsto make a basic graphical display to show how many people receiveddifferent gradesfor a piece of work on a module. You are required to write a program in C++that achieves this. The program is in a number ofparts.1. The program should allow the tutor to enter in the various marks which the studentshave been awarded, until the tutor entersin a mark exceeding 100. At this point the programshould display a histogram. Each star represents a student who achieved a module mark inthe range shown.This is an example of the output. The example below shows the distribution of marksfor 20students. Your program should work with any number of student marks entered.0-29 ***30-39 *****40-69 ********70-100 ****20 students in total.? As the tutor enters each mark, a counter should count the number of student’s markswhich have been entered.? Use the same 4 category ranges shownhere.? Make sure the display is neatly formatted asabove.? Your program should make use of ‘loops’ for the display of each category.
