    i have to write a program that will compute the amount someone will have to pay for a parcel of land...

    Input: The Length and Width in feet
    Price Per Acre

    Extra information: 1 acre=43560 sq ft.

    Calculation:
    Total area in square feet.
    Total acreage
    total amount of the sake

    Output:
    total area in square feet
    total acreage
    total amount of the sale


    i am so confused on how to do this...i have read all of the tutorials on cplusplus and am using microsoft visual studios to do it

    i put in #include "stdafx.h"
    #include<iostream>
    using namespace std;

    im kind of confused what to put after int...i thought it should be like length and width...i think i have to make up a value for something

    can anyone help me??

    You need a book which can help you with the Hello world program because you don't put int after you code but you should start with the main function.

    But the first post sounded like what you should be putting after the #include.

    oh im sorry...i did put that before all of that- i was just unsure what to put after that...I have
    double Length,
    Width,
    Price,
    Acres,
    Sq_Feet,
    Amount;
    and i have the cin's and cout's

    the only thing i cant figure out is what to put the amount equal to in order to build it and get a reply

    I'm not sure exactly what you want, but your program might look something like this:

    Code:
    //Price per Parcel
    
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
        int length , width , price , sq_feet , total , acreage;
        
        //Use cout to ask user for length
        cin >> length;
        
        //Use cout to ask user for width
        cin >> width;
        
        //Use cout to ask for the price per square foot
        cin >> price;
        
        length * width == sq_feet;
        
        acreage = sq_feet / 43560;
        
        total = sq_feet * price;
        
        //Send sq_feet to cout
        //Send acreage to cout
        //Send total (price) to cout
    
        return 0;
    }
    Maybe if you explain it a little better it would be easier to help. (Sorry, I think I'm sounding a bit like shabbir in saying that.)
