Using C++, generate a text-based histogram for a quiz given to a class of students. The quiz is graded on a scale from 0 to 5. Write a program that allows the user to enter grades for each student. As the grades are being entered, the program should count, using an array , the number of 0s, the number of 2s, the number of 4s. The program should be capable of handling an arbitrary number of student grades. You can do this by making an array of size 6, where each array element is initialized to zero. Whenever a zero is entered, increment the value in the array at index 0. Whenever a one is entered, increment the value in the array at index 1, and so on, up to index 5 of the array .
