Question

There are three seating categories at a stadium. For a softball game, Class A seats cost $15, Class B seats cost $12, and Class C seats cost $9. Write a program that asks how many tickets for each class of seats were sold, then displays the amount of income generated from ticket sales. Format your dollar amount in fixed-point notation, with two decimal places of precision, and be sure the decimal point is always displayed.

Using the following test data:
1 2 3

Your output should look like this:
Enter the number of Class A tickets sold: Enter the number of Class B tickets sold: Enter the number of Class C tickets sold:
Total income from sale of tickets is $66.00

This is C++ and use visual studio 2017 please.

Use blank lines to separate the major parts of your main function and show your output.

Answer 1

Source Code in C++:

#include <iostream>

using namespace std;

int main()
{
int a,b,c; //variables to hold number of ticket for each class
cout << "Enter the number of Class A tickets sold: ";
cin >> a; //taking number of class A tickets as input
if(a<0) //validating input
{
cout << "No. of tickets cannot be negative." << endl;
//error message
return 1; //terminating the program
}
cout << "Enter the number of Class B tickets sold: ";
cin >> b; //taking number of class B tickets as input
if(b<0) //validating input
{
cout << "No. of tickets cannot be negative." << endl;
//error message
return 2; //terminating the program
}
cout << "Enter the number of Class C tickets sold: ";
cin >> c; //taking number of class C tickets as input
if(c<0) //validating input
{
cout << "No. of tickets cannot be negative." << endl;
//error message
return 3; //terminating the program
}
double total;
total=15.00*a+12.00*b+9.00*c; //calculating total
printf("Total income from sale of tickets is $%.2lf",total); //printing total
return 0;
}

Output:
