Variable Manipulation

[casey2007]

Hi guys, I am new to C++ and I am starting to learn the basics of it. I am doing my own little assignment and I was wondering if you could help?


Heres my source code:

// Casey's Wire Fence Calculator
 
#include <iostream>
 
 
using std::cout;
using std::endl;
using std::cin;
 
 
int main()
{
    cout << "Casey's Wire Fence Calculator" << endl;
 
    float rectangleLength = 0.0, rectangleWidth = 0.0, rectanglePerimeter = 0.0, wireCost = 0.0, totalCost = 0.0;
 
    // get the length and width values from the user
    cout << "Please enter the rectangle length ";
    cin >> rectangleLength;
 
    cout << "Please enter the rectangle width ";
    cin >> rectangleWidth;
 
    // Perimeter of a rectangle is LxWxLxW = P
 
    rectanglePerimeter =(2*(rectangleLength * rectangleWidth));
 
    cout << " The rectangle perimeter is ";
    cout << rectanglePerimeter << endl;
 
    cout << endl;
 
    cout << "Please enter the cost per metre of wire ";
    cin >> wireCost;
 
 
    return 0;
}
// end of main() function
 

I need help because I know how to multiply two variables together but, I want to multiply another two variables together and then multiply the two answers to the two equations I have done. How do I go about that?

Thanks Casey :)

What exactly do you mean? The sample program you've written looks very good so far - what else do you need to do?
