Combine the programs from Programming Write a program to read a list of nonnegative integers and to display the largest integer, the smallest integer, and the average of all the integers. The user indicates the end of the input by entering a negative sentinel value that is not used in finding the largest, smallest, and average values. The average should be a value of type double so that it is computed with a fractional part. Write a program to read a list of exam scores given as integer percentages in the range 0 to 100. Display the total number of grades and the number of grades in each letter-grade category as follows: 90 to 100 is an A , 80 to 89 is a B, 70 to 79 is a C, 60 to 69 is a D, and 0 to 59 is an F. Use a negative score as a sentinel value to indicate the end of the input. (The negative value is used only to end the loop, so do not use it in the calculations.) For example, if the input is 98 87 86 85 85 78 73 72 72 72 70 66 63 50 -1 the output would be Total number of grades = 14 Number of A's = 1 Number of B's = 4 Number of C's = 6 Number of D's = 2 Number of F's = 1 to read integer exam scores in the range 0 to 100 and to display the following statistics:
Total number of scores
Total number of each letter grade
Percentage of total for each letter grade
Range of scores: lowest and highest
Average score
As before, enter a negative score as a sentinel value to end the data inputand display the statistics.
