It is missing a function prototype as well, use the floor or ceil function to fix the total output. #include<iostream>#include<iomanip>using namespace std; /* This is a function that calculates the charge of parking for the given amount of time (in hours) */double calculateCharges(double hours) {if (hours <= 3.0) { // If the time is less than 3 hours.return 20.0; // Charge a fixed amount of $20}else {double charge = 20.0 + (hours - 3.0) * 5; // Calculate the charge, which is $20 + ($5/hour for excess of 3 hours)if (charge >= 50.0) { // If the charge is greater than $50return 50.0; // Charge the maximum amount of $50}return charge;}}int main() {// Declare the variablesdouble hoursParked[3], // For storing the number of hours parkedparkingCharges[3], // For storing the parking chargestotalHours = 0, // For storing the total hours all cars were parkedtotalCharges = 0; // For storing the total…
USE C++ ONLY <IOSTREAM> THANK YOU 2. Write a lunch order program which allows to select lunch items accordingto the lunch menu provided below. (B) Burger with French Fries – 8.99 (C) Chicken and Rice – 9.50 (T) Tuna Sandwich – 10.49 (E) Exita) Write a function void takeOrder(int& burger, int& chicken, int& tuna);which will display the menu item, validate the entries and count how manyorders for each menu item: - Request one character for a lunch item. Menu options must be case insensitive (i.e. ‘E’ and ‘e’ must work). - Validate the input value. - Handle the menu (with a switch statement) to record how many orders for each item is taken. - The function must use pass by reference parameters to return how many orders for each menu item. - End the function only if Exit option is selected.b) Write a function payOrder(int burger, int chicken, int tuna) to print out how many orders are taken for each menu and calculate the total price.c) Call the functions in main() as…
Please code using C++ and only using the header <iostream>. Any others will not be accepted. Please also avoid using the folat data type and instead ultilize double. Attached is a hint as it must include the member functions of cout. Thank you!

Use C++ I need three files, one main.cpp file, one rational.cpp file and one rational.h file. I'll put the code for the main.cpp file and rational.h file below. No need to change them I just need the rational.cpp file. Modify the code to have operator overloading functions with the following operators.==, <, <=, >, >=, +, -, *, /Use the Rational interface and main code in the next page. main.cpp: #include <iostream>#include "rational.h"int main(){ Rational r1, r2; char answer = 'y'; while (answer == 'y') { cout << "Enter the first fraction (e.g. 3/4) : "; cin >> r1; cout << "Enter the second fraction (e.g. 3/4) : "; cin >> r2; cout << "r1 : " << r1 << endl; cout << "r2 : " << r2 << endl << endl; cout << "r1 + r2 = " << r1 + r2 << endl; cout << "r1 - r2 = " << r1 - r2 << endl; cout << "r1 * r2 = "…
