C Programming #2 - Sample Programs

Some small programs you can test if would like to program with the C computer programming language.


Here is a program called welcome.c that will display some text on the screen. You can modify it to display any text you want. Note, comments for your personal programming use are placed between: /* and */. They often are used to describe a portion of code as a reference if you need it later. The text between the comment symbols/syntax will be skipped over by the compiler/computer.

/* welcome.c Jan 1, 2007
This program will display some text on the screen.
*/

#include "stdio.h"

void main(void)
{

printf("Welcome");

return;
}


Here is a program that will sound a beep, that can perhaps be used to signal an event, etc.

/* beep.c
Jan 2, 2007
This program will sound a beep alert sound.
Use more \a characters to lengthen the sound.
*/

#include "stdio.h" /* automatically include the code of stdio.h that contains the code of the functions that are used to display text */

void main(void)
{

printf("\a");

return;
}

To compile the c source program to an .EXE file/program, you would type in something like
the following on the command line:

tcc welcome.c or:
tcc Cprograms\welcome.c

The output should be a file called: welcome.exe
Windows will automatically create an icon for you, so that you can click on it and execute/run the program in a graphical manner, rather than a text/console/command-line manner.

---------------------------------------------

TCC can also be used to create some Windows. TCC included an example that creates a window
and displays some text:

tcc examples\hello_win.c

Windows programming will not be covered in any detail here, but will give some links where you can start. Some will be batch files, some will be command line commands (essentially DOS), and some will be for Windows.
