Question
For intro to programming, using bare minimum c++. As much info as possible would be appreciated.
Lab 9-7: Overloading Functions In this lab, you complete a partially written C++ program that computes hotel guest rates at Cornwall’s Country Inn. The program is described in Chapter 9, Exercise 11, in Programming Logic and Design. In this program, you should include two overloaded functions named computeRate(). One version accepts a number of days and calculates the rate at $99.99 per day. The other accepts a number of days and a code for a meal plan. If the code is A, three meals per day are included, and the price is $169.00 per day. If the code is C, breakfast is included, and the price is $112.00 per day. Each function returns the rate to the calling program where it is displayed. The main program asks the user for the number of days in a stay and whether meals should be included; then, based on the user’s response, the program either calls the first function or prompts for a meal plan code and calls the second function. Comments are included in the file to help you write the remainder of the program.
1. Open the source code file named Cornwall.cpp using Notepad or the text editor of your choice.
2. Write the C++ statements as indicated by the comments.
3. Save this source code file in a directory of your choice, and then make that directory your working directory.
4. Compile the source code file Cornwall.cpp. 5. Execute the program.
#include <iostream>
#include <string>
using namespace std;
double computeRate(int);
double computeRate(int, string);
int main()
{
int days;
string mealPlan;
string question;
double rate = 0.0;
cout << "How many days do you plan to stay? " << endl;
cin >> days;
cout << "Do you want a meal plan? Y or N: " << endl;
cin >> question;
// Figure out which arguments to pass to the computeRate() function and
// then call the computeRate() function
cout << "The rate for your stay is $" << rate << endl;
return 0;
} // End of main() function
// Write computeRate functions here.
Explanation / Answer
#include <iostream>
#include <string>
using namespace std;
double computeRate(int);
double computeRate(int, string);
double computeRate(int days)
{
return days*99.99;
}
double computeRate(int days,string code)
{
if(code=="A")
{
return (days*99.99)+169;
}
else if(code=="C")
{
return (days*99.99)+112;
}
}
int main()
{
int days;
string mealPlan;
string question;
double rate = 0.0;
cout << "How many days do you plan to stay? " << endl;
cin >> days;
cout << "Do you want a meal plan? Y or N: " << endl;
cin >> question;
// Figure out which arguments to pass to the computeRate() function and
// then call the computeRate() function
rate=computeRate(days);
cout << "The rate for your stay is $" << rate << endl;
if(question=="Y")
{
cout<<"which meal plan you want A or C";
cin>>mealPlan;
rate=computeRate(days,mealPlan);
cout << "The rate for your stay with meal plan is $" << rate << endl;
}
return 0;
} // End of main() function
