3 fields in one line "homework help"

I don't expect anyone to do my homework for me but can someone give me some pointers... I would like to have 3 entry fields in one line, average all 3 entrys, and also the sum of all 3 for example

Enter Northern Sales ______, _______, _______,
Enter Northern Sales 100, 200, 300

The actual problem is:
Create a program that displays the sum of sales amounts made in each of four regions during a three month period. The program should also display the total sales made during the three months. The program should display each regions total sales for the three-month period, and the company's total sales for the three month period.

By the way if you do read this I realized while typing this up that it doesn't need the average so I just need tips of 3 fields in one line... I have to take out the average part

Code:

---

#include <iostream>

using std::cout;
using std::cin;
using std::endl;

int main()
{
//declare variables
double north = 0.0;
double south = 0.0;
double east = 0.0;
double west = 0.0;
double average = 0.0;
double averageNorth = 0.0;
double averageSouth = 0.0;
double averageWest = 0.0;
double averageEast = 0.0;
double norTol = 0.0;
double souTol = 0.0;
double easTol = 0.0;
double wesTol = 0.0;


//input value
cout << "Enter Northern Regional Sales  ";
cin >> north;
cout << "Enter Southern Regional Sales  ";
cin >> south;
cout << "Enter Eastern Regional Sales  ";
cin >> east;
cout << "Enter Western Regional Sales  ";
cin >> west;

//calculate change

averageNorth = (north/3);
averageSouth = (south/3);
averageWest = (west/3);
averageEast = (east/3);


//display output
 
cout <<"Northern Regional Average: " << averageNorth <<endl;
cout <<"Northern Sales Total: " << norTol<<endl;
cout <<"Southern Regional Average: " << averageSouth <<endl;
cout <<"Northern Sales Total: " << souTol<<endl;
cout <<"Eastern Regional Average: " << averageEast <<endl;
cout <<"Eastern Sales Total: " << easTol<<endl;
cout <<"Western Regional Average: " << averageWest <<endl;
cout <<"Western Sales Total: " << wesTol<<endl;
system ("pause");

return 0;
} //end of main function

Subsequent ">>" inputs will simply ignore whitespace, regardless of whether subsequent entries are on the same line or not. Should be good enough. You'll have to deal with the commas manually, though, or remove them.

Can you give me an example of where I would put them? on the "cin" or "cout" line?

Why would you try to do input on a cout line?

Good point... How would I put it in the cin line...

Just do 3 cin statements? I mean, there are ways to condense it further, but have you tried the basics?

If you mean starting with baby steps? Basics? Yeah I am in Introduction to Programming, The class only meets once a week for 2 hours. I'm actually supposed to make a loop out of this thing but I'm going to turn it in as is because I don't get it. I will probably drop the class even though I would have to pay my scholarship back... I'm seriously ripping my hair out here...

Here is an example of how to take multiple input from one line.

Code:

---

#include <iostream>
using namespace std;

int main()
{
    int number1=0;
    int number2=0;
    int number3=0;


    cout<<"Enter 3 numbers seperated by a space"<<endl;

    cin >>number1 >> number2 >> number3;    //    <---- MULTIPLE INPUT

    cout<<"Number1 : "<<number1<<endl;
    cout<<"Number2 : "<<number2<<endl;
    cout<<"Number3 : "<<number3<<endl;

    system("PAUSE");

    return(0);
}

As for removing commas. If you tell the user to seperate using whitespace and they put commas its not your fault.

You could gracefully handle commas as well, but that's an additional level of complication which it's probably best not to worry about just yet. For now, allowing input to enter a fail state if it encounters an unexpected type (like a comma when it wants an int) is probably acceptable.
