Question

3. Write a C++ program to choose one of the following five options for your summer vacation 1. Hawaii 2. Bahamas 3. Cancun 4. Las Vegas 5. Europe Your program should select one of the above option. Once the option is selected then your program should select one of the following airlines: 1. US Air 2. Delta 3. Southwest 4. Continental 5. American Airline Once the airline is selected then read number of passengers airfare for round trip. Calculate the total charge.

you pick the charge rate per company

Answer 1

(Note: The question doesn't exactly tell whether to select the airline and destination randomly or ask it from the user. Thus, I'm assuming that it intends to ask it from the user, which is the more obvious option out of the two.)

The complete C++ program for the given problem is given below:

#include<iostream>

using namespace std;

int main()

{

int fares[][5]={ {140, 120, 190, 165, 178},
{155, 130, 188, 170, 182},
{138, 123, 200, 168, 180},
{142, 128, 200, 172, 176},
{140, 130, 185, 170, 177} };

//fares[0] represents the charges charged by US Air, fares[1] for Delta, fares[2] for Southwest, fares[3] for Continental, and fares[4] for American Airline.

int destination, airline, n, total_fare;

cout<<"Choose the destination for your summer vacation:";
cout<<"\n1. Hawaii";
cout<<"\n2. Bahamas";
cout<<"\n3. Cancun";
cout<<"\n4. Las Vegas";
cout<<"\n5. Europe";
cout<<"\n\nEnter your choice (1-5): ";
cin>>destination;
  
cout<<"\nSelect the airlines you want to travel with:";
cout<<"\n1. US Air";
cout<<"\n2. Delta";
cout<<"\n3. Southwest";
cout<<"\n4. Continental";
cout<<"\n5. American Airline";
cout<<"\n\nEnter your choice (1-5): ";
cin>>airline;
  
cout<<"Enter the number of passengers: ";
cin>>n;
  
total_fare = n * fares[airline-1][destination-1];
cout<<"The total fare for round trip for "<<n<<" passengers is "<<total_fare<<"$.";
return 0;

}

• As asked in the question, the charges per company are decided by the program itself. The 2-dimensional array "fares" represents the charges for all the destinations for all the airlines. fares[0] represents the charges charged by US Air, fares[1] for Delta, fares[2] for Southwest, fares[3] for Continental, and fares[4] for American Airline.
• Next, the program asks the user to choose the destination. The destination number is stored in the variable destination.
• Next, the program asks the user to choose the airline. The airline number is stored in the variable airline.
• Now, the program asks the user to enter the number of passengers. This information is stored in the variable n.
• The fare for the round trip is now calculated by the formula: total_fare = n * fares[airline-1][destination-1]
• We have subtracted 1 from both airline and destination because the array index starts from 0 and not 1.
• The quantity fares[airline-1][destination-1] gives the charges of the "airline" airline for the "destination" destination.
• The total fare is being printed on the screen.
