Chapter 9, Problem 8PP

Write a program that outputs a histogram of student grades for an assignment. The program should input each student’s grade as an integer and store the grade in a vector (covered in Chapter 8). Grades should be entered until the user enters −1 for a grade. The program should then scan through the vector and compute the histogram. In computing the histogram, the minimum value of a grade is 0 but your program should determine the maximum value entered by the user. Use a dynamic array to store the histogram. Output the histogram to the console. For example, if the input is:

20

30

4

20

30

30

−1

Then the output should be:

Number of 4's: 1

Number of 20's: 2

Number of 30's: 3
