Please Help! Write a C++ program to read integers until 9999 is entered (called sentinel – sentinel is used to indicate the end of input and must not to be considered as the valid data for the computation). Perform the following operations for the integers entered by the user. Display the sum of the numbers less than 100 Display the smallest of the positive integers Display the largest of the negative integers Display how many integers are between 100 and...

Question 19 4 pts Using the program below, please complete the program by adding 2 functions as follow: 1. A function named getAverage that calculates and returns the Average. 2. A function named getMaximum that returns the maximum of the three numbers. Make sure to use the proper data types for all variables and functions. #include <iostream> using namespace std; //function getAverage //function getMaximum int main(int argc, char** argv) { int x, y, z; cout << "Enter three whole numbers:...
This is for a C++ program: I'm almost done with this program, I just need to implement a bool function that will ask the user if they want to repeat the read_course function. I can't seem to get it right, the instructions suggest a do.. while loop in the main function. here is my code #include <iostream> #include <cstring> #include <cctype> using namespace std; const int SIZE = 100; void read_name(char first[], char last[]); void read_course(int & crn, char des[],...
