/*
Week 4 Program
Lets continue with our Coke Machine program from week 3.
Now, you will need to add 3 functions to it and move the
appropriate code into them. Create an InsertMoney function
and move all of the money insertion code into it. Create a
Menu function that will display the drink choices and Create
a Change function that will give the user his or her change.
Here’s how the main function will look
main()
//Beginning of loop
Call the insert money function
Call the DisplayMenu function
Call the GiveChange function
//end of loop
//end of main
At this point, a menu( which is also a separate function) will
display saying something like:
What would you like?
Press 1 for Coke
Press 2 for Dr. Pepper
Press 3 for Pepsi
Once they make their choice, you can dispense the drink and any
change that they may owe. Lets use a function for this also.
To be clear, I’m asking you to create three functions, not counting Main.
1. You should have one function to accept and keep track of the money.
2. One function to display the menu
3. One function to dispense the drink and give the change
You may choose to add more functions to your program. If you wish to do so,
or if you wish to have one function call another one rather than having to
return to main each time, that’s fine.

cin >> selection;
if (selection == 1)
{
// Incrementing the array for each soda bought
a[0] = a[0]+1;
cout << "Thank you and enjoy your Coke!" <<endl;
}
elseif (selection == 2)
{
a[1] = a[1]+1;
cout << "Thank you and enjoy your Pepsi!" <<endl;
}
elseif (selection == 3)
{
a[2] = a[2]+1;

}
void giveChange()
{
if (inMachine > sodaPrice)
{
cout << "Your change is: $" << (inMachine - sodaPrice) << endl;
}
// Clearing the variables
inMachine = 0;
selection = 0;
cout << "Would you like to purchase another soda? Y or N ";
cin >> more;
system("CLS");
}
// Displaying the totals of soda bought
cout << "You have purchased " << a[0] << " Coke(s)" << endl;
cout << "You have purchased " << a[1] << " Pepsi(s)" << endl;
cout << "You have purchased " << a[2] << " Dr. Pepper(s)" << endl;
system("PAUSE");
}
I added two '}' braces after 96 and deleted the one '}' on 135.
Did you compile and run this or just a visual inspection? Because I get the following errors:
