    Question Need help with a C assignment due on 9/23 (Friday)

    Hi I've never posted before on this board. (actually, I've just now signed up). But anyways; I need help with a homework assignment that will probably seem extremely easy to everyone here, I've never done any programming of any sort before so I was wondering if someone could show me how to do this.

    Thanks in advance,
    John Putnam

    The question:
    Write a program that takes the length and width of a rectangular yard and the length and width of a rectangular house situated in the yard. Your program should compute the time required to cut the grass at the rate of two square feet a second.

    We're not going to write your code for you. If you're having trouble, post what you have, and we'll help you out.
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    #include <stdio.h>
    int main<void>
    printf<"Input Length of yard\n">;
    scanf< >;
    printf<"Input Width of yard\n">;
    scanf< >;
    printf<"Input Length of House\n">;
    scanf< >;

    It should not take you a week to do something like this. Surely, you have the internet, and potentially a good text and teacher at your fingertips. You are mixing up <> and () with function definitions/calls. Check out this very simple tutorial on the subject of console interaction:

    Tonto - excellent tutorial recommendation!

    JohnnyBoy268 - please read the forum guidelines, located at Please also refer to the sticky at the top of each forum concerning the proper way to post code.

    I hesitate to tell you that had you followed the guideline regarding searching the forums, you would have found how many other people are working on this same assignment.

    After that, you should find the area of both rectangles (the yard and the house) using the formula area = length * width . Then you need to subtract the area of the house from the area of the yard to get the total grass.

    And now with less than 24 hours to go, you post a panic message saying "please help".

    > printf<"Input Length of yard\n">;
    Jeez, someone else used () to include a file, and now you're using <> to call a function.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
