CMSC 104
Highly Recommended Sample Program

The Objective

To give you practice going through the steps of creating, compiling, running and submitting a project.

The Task

Traditionally, every C programmer writes this program as their very first. It is a simple program that displays the text "Hello World" on the screen. We will continue that tradition and give you practice before the real projects are assigned.
  1. Using your text editor, create a file named hello.c that looks just like this one, except that your should replace all the stuff between the < and > symbols with real information.
    For example, replace <your name here> with your name.

  2. compile your file with the Unix command
    cc hello.c

    If you are as bad a typist as most programmers, you will get some compiler errors. Use your text editor to re-edit your file to fix the errors, then recompile. If you typed well, the compiler did not complain. You may find it interesting to go back and intentionally mistype some characters to get a feel for the kinds of errors the compiler can generate.

  3. run your program by typing a.out at the Unix prompt

Although this sample project carries no points and does not count toward your grade, you will find that having done this project will make your real projects go faster.
