(solution) In Visual Basic construct a program that reads a set of exam

In Visual Basic construct a program that reads a set of exam scores from the user until it receives a negative input. The negative input should not be use in your calculations.

Using A = 90 to 100, B= 80 to 89, C = 70 to 79, to 69, and F= 0 to 59 compute the followings:

The total number of students in the class (10 points)

The total numbers of student for each letter grade (15 points)

The percentage of total number of student for each letter grade (10 points)

The range of scores for each letter grade (15 points)

The average score for each letter grade (10 points)

The entire class average (10 points)
