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 parameter variable, and validate that it is not lower than 0 or higher than 100. 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 one of the five scores to drop.
INSTRUCTIONS: Write a C++ script/code to do the given problems.
MOVIE PROBLEM: Write a function that checks whether a person can watch an R18+
rated movie. One of the following two conditions is required for admittance:
The person is atleast 18 years old.
• They have parental supervision.
The function accepts two parameters, age and isSupervised. Return a boolean.
Example:
acceptIntoMovie(14, true) → true
acceptIntoMovie(14, false) → false

- Write the definition of a void function that takes as input three decimal numbers. The function returns the sum and average of the three numbers. If the average is greater than or equal to 70, it returns "Pass"; otherwise it returns "Fail".arrow_forwardThe following program contains a simple class that is designed to allow a user to enter an integer value within a specific range. The code prompts the user with a message that explains the limits of the valid range of values, but it does not force the user to enter legal values. We have examined a number of approaches for dealing with this problem. One approach is to place an assert statement in the getValue function to terminate the program when an illegal input occurs. An alternative approach is to put a loop inside the getValue function that prompts the user repeatedly until a valid value is received. Neither of these approaches is satisfactory, because they force the user to adopt a specific approach to dealing with the error. If you compare the execution of a program with the operation of a business, you will notice that both consist of a hierarchy of classes and functions. In a business, we expect the people in the upper layers of the company (managers) to set policies and the…arrow_forwardDecryption Key A|B|C| D|E|F|G|H|I|J|K|L|M N|O|P|Q|R|S|T|U|V|W|X|Y|Z (letter above equals below, and vice versa) As you can see, A becomes N, B becomes O and so on. Your job is to write a program, with at least four functions, including main, which must do the following: 1. Ask user whether they want to encode or decode a message - if no, then terminate 2. Take the input string from the user, store it in dynamic memory (use new) 3. As appropriate, encode or decode the message using Rot13. 4. Output the encoded/decoded message 5. Delete the input string from dynamic memory (use delete)arrow_forward
