    How to acquire a C compiler

    In this article, we explain what you need to do to acquire a C compiler and how to get your program ready for execution.

    First, you need to acquire a C compiler. There are many C compilers available for free on the Internet. Our favourite is the Tiny C compiler available at

    Go to the site, scroll to Download and click on the link next to “Windows binary distribution”. Save the file to your Desktop or any other convenient place of your choosing. Extract the files to a folder called TinyC, say, on your C: drive. You should see the following in the folder:

    TinyCFiles01 The compiler is in the file tcc.exe. Tiny C is a blazingly fast compiler. It is also very small. The complete compiler with support files is about one megabyte – it can fit on a diskette!

    How to store your program

    In C Programming For Beginners – Part 3, we met the following program which calculates the area of a square:

    #include <stdio.h>
    main() {int a, s;

     printf("Enter length of side: ");scanf("%d", &s); //store length in sa = s * s; //calculate area; store in aprintf("\nArea of square is %d\n", a); }

    Next, you must type the program to a file: you can name the file AreaOfSquare.c. It is recommended that you use .c for any file that contains a C program.

    You must store your program as a text file. You can use Notepad or WordPad. You can use Word (or another word-processor) but be sure to save it as a text file.

    For convenience, we assume that you have created a folder C:\CPrograms and will store your programs there.

    Summary: we assume the Tiny C compiler has been installed in


    and your program is stored in a file AreaOfSquare.c in the folder C:\CPrograms.

    In the next article, we show how to compile and run the program.
