PLease make this program work in C++ // This program has three functions: main, beep, and beeper #include <iostream>using namespace std;// Definition of function Beeper. This function displays a message. void Beeper(void) { cout << "I am now inside the function Beeper.\a\a\a\n"; } // Definition of function Beep. This function calls the function Beeper. void Beep(void) { cout << "I am now inside the function Beep.\a"; Beeper(); // Call function Beeper cout << "Now I am back in Beep.\a"; } void main(void) { cout << "I am starting in function main.\n"; Beep(); // Call function Beep cout << "Back in function main again.\n" }
(Apartment problem) A real estate office handles, say, 50 apartment units. When the rent is, say, $600 per month, all the units are occupied. However, for each, say, $40 increase in rent, one unit becomes vacant. Moreover, each occupied unit requires an average of $27 per month for maintenance. How many units should be rented to maximize the profit? Write a program in C++ that prompts the user to enter: The total number of units. The rent to occupy all the units. Amount to maintain a rented unit. The increase in rent that results in a vacant unit. The program then outputs: The number of units to be rented to maximize the profit The maximum profit Since your program handles currency, make sure to use a data type that can store decimals with a decimal precision of 2.

AHPA #9:A Gas Station• You have been asked to create a C program to manage the gaspumps at a gas station. The station has four pumps connectedto four tanks with capacities: 100, 75, 50, and 150. Every timea car fills up it takes 10 gallons. You’ll know that a car hasarrived because the carArrived function will return with apump number. After a car has filled up, print out the currentcontents of all four tanks.• Write a C program that can track each of the four tanks. Updatethe amount of gas remaining in a tank when a car fills up.When a tank gets to less than 20 gallons of gas remaining,make a call to request a refill truck visit the station(refillRequest). This will cause the tank to berefilled automatically
Q1) How to use C code to write a C program segment to prompt a user for entering an integer and save it into an “option”variable. In your program, you have to make sure the value (option) entered by the user is either1, 2 or 3 only. Otherwise, display a message asking the user to re-enter the “option” value.[Note: Assume that all the necessary variables have been declared]

C++ PROGRAMProblem Statement: A 4th grader is having trouble with Permutation and Combination problem in Mathematics, so a friend offered help to create a program they can use. The program contains 3 options, 1st option is for Permutation, 2nd option is Combination and 3rd is for terminating the system. For option 1, Permutation, they uses the following formula: nPr = ; where r must not be greater than n. It should not proceed if this condition is not met. For 2nd option, Combination, they uses the formula : nCr = ; where r must not be greater than n as well. For the 3rd option, the program owner’s information shall be displayed, like name, subject code and account number, before the program terminates. Requirements: Develop the required system and use cpp for the file name Remember that both n and r are variables, their values shall only be entered at run time. The program requires the use of any looping The program requires the use of any conditional Introduce at…
