The Problem__:
Write a program that calculates the average of a group of test scores, where the lowest score in the group is dropped. It should use the following functions:
⚫ void getScore() should ask the user for a test score, store it in a reference param- eter variable, and validate it. This function should be called by main once for each of the five scores to be entered.
⚫ void calcAverage() should calculate and display the average of the four highest scores. This function should be called just once by main and should be passed the five scores.
⚫int findLowest() should find and return the lowest of the five scores passed to it. It should be called by calcAverage, which uses the function to determine which of the five scores to drop.
Input Validation: Do not accept test scores lower than 0 or higher than 100.
YOU MUST USE THE STATED FUNCTIONS AND COMPLETE Input VALIDATION.
**DO NOT use an ARRAY OR GLOBAL VARIABLES!!.
you MUST USE function prototyping
TEST THE FUNCTION TWICE.…
Print "userNum1 is negative." if userNum1 is less than 0. End with newline. Assign userNum2 with 4 if userNum2 is greater than 9. Otherwise, print "userNum2 is less than or equal to 9.". End with newline.

- (Misc. application) a. Write a program to reverse the digits of a positive integer number. For example, if the number 8735 is entered, the number displayed should be 5378. (Hint: Use a do statement and continuously strip off and display the number’s units digit. If the variable numinitially contains the number entered, the units digit is obtained as (num % 10). After a units digit is displayed, dividing the number by 10 sets up the number for the next iteration. Therefore, (873510)is5and(8735/10)is873. The do statement should continue as long as the remaining number is not 0.) b.
