Chapter # 8 (Arrays) Problem 1 1. Histogram Generate a text-based histogram for a sequence of grades to a class of students. The grades are l'A'- 'D', 'F'). Write a program that allows the user to enter grades of students in upper/lower case. As the grades are being entered, the program should count, using an array, the number of A's, the number of B's, the number of C's, the number of D's, and the number of F's. The program should be capable of handling an arbitrary number of student grades. However, the input should end when an invalid grade is encountered. To design your counters, use an array of size 5 where each array element is initialized to zero. Whenever an 'A" or 'a' is entered, increment array[0). Whenever a 'B' or 'b' is entered, increment array[1), etc. up to array[4]. Output the histogram count and the bar- chart too as shown below. Sample input / output: Enter sequence of valid grade ['A'-'F'] ending with an invalid grade to stop: 6BBC CA a a AdDDd afFFBa Ade 7 grade(s) of A ; bar-chart: ***** 4 grade(s) of B; bar-chart: *** 2 grade(s) ofC; bar-chart: ** 5 grade(s) ofD; bar-chart: ***** 5 grade(s) of F; bar-chart: *** Enter sequence of valid grade ['A'-'F'] ending with an invalid grade to stop: abcdfdbbBBAcDffFFFp 2 grade(s) of A ; bar-chart: * 5 grade(s) of B; bar-chart: ***** 2 grade(s) of C; bar-chart: ** 3 grade(s) of D; bar-chart: *** 5 grade(s) of F; bar-chart: ***
