Answer to Question #124409 in C++ for emmanuel

Question

Write a program that computes the total ticket sales of a concert . there are three types of seating’s : A, B, and C. the program accepts the number of tickets sold and the price of a ticket for each of the three types of seats. The total sales are computed as
totalSales = numberofA_Seats * priceperA_Seat +
numberofB_Seats * priceperB_Seat +
numberofC_Seats * priceperC_Seat ;
Write this program, using only one class, and the main function of the program.

Answer 1

// the preprocessing directives

#include <iostream>

#include <iomanip>   // setprecision(2) and fixed

using namespace std;

// claas declaration

class Sales

{

 private:

  float priceperA_Seat;   

  float priceperB_Seat;

  float priceperC_Seat;

  int numberofA_Seats;   

  int numberofB_Seats;

  int numberofC_Seats;

 public:

    //default constructor

Sales () {

    numberofA_Seats = 0;   

    numberofB_Seats = 0;

    numberofC_Seats = 0;

   priceperA_Seat = 0;   

    priceperB_Seat = 0;

    priceperC_Seat = 0;

   }

   //no-default constructor

Sales (int nA, int nB, int nC, float pA, float pB, float pC) {

   numberofA_Seats = nA;   

    numberofB_Seats = nB;

    numberofC_Seats = nC;

    priceperA_Seat = pA;   

    priceperB_Seat = pB;

    priceperC_Seat = pC;

   }

float totalSales(){

   float totalSales = 0;

   totalSales = numberofA_Seats * priceperA_Seat +

   numberofB_Seats * priceperB_Seat +

   numberofC_Seats * priceperC_Seat;

   return totalSales;

}

};

int main() {

   int numberA, numberB, numberC;

   float priceA, priceB, priceC;

   cout << setprecision(2) << fixed;

   cout << "Number of tickets A sold: ";

   cin >> numberA;

   cout << "Price of a ticket A: ";

   cin >> priceA;   

   cout << endl <<"Number of tickets B sold: ";

   cin >> numberB;   

   cout << "Price of a ticket B: ";

   cin >> priceB;   

   cout << endl << "Number of tickets C sold: ";

   cin >> numberC;   

   cout << "Price of a ticket C: ";

   cin >> priceC;

   // Declare a Sales class object      

   Sales s01(numberA, numberB, numberC, priceA, priceB, priceC );

   cout << endl <<"The total ticket sales of a concert: $"<<s01.totalSales();

   return 0;
