Whenever there is need to store a group of data of the same type in the memory, arrays are used. Two terms have been described here Array and String. Strings in C are represented by the array only, therefore, it would be convenient to describe strings separately in the same block but in the different …
The Element of array are initialized in the same way as the ordinary variables. Example: int num[6]={2,4,5,35,12,12,67}; An example showing the index and its corresponding data (prices) > An example program of entering data into Array: Out put of the program In this example, using the for loop, the process of asking and receiving the marks …
Graphics programming in C Language is discussed rarely. We will discuss some important functions of graphics.h in C Language, at the end we will make a simple program to demonstrate the use of graphics functions. So let’s start with the description of important functions and their use. Graphics Drivers Graphics drivers are a subset of …
Graphics.h Below are the important functions and their description mostly used in graphics applications in C Language. Function initgraph This function is used to load the graphics drivers and initialize the graphics system. For every function, that uses graphics mode, graphics mode must be initialized before using that function. void far initgraph(int far *driver, int …

Turbo C has a good collection of graphics libraries. If you know the basics of C, you can easily learn graphics programming. To start programming, let us write a small program that displays a circle on the screen. /* simple.c example 1.0 */ #include<graphics.h> #include<conio.h> void main() { int gd=DETECT, gm; initgraph(&gd, &gm, “c:\\turboc3\\bgi ” …
1. Setup Driver Development Environment Step 1: Install following packages on the development computer Platform Software Development Kit (SDK), Microsoft Visual C (must use the version specified in DDK, newer version might not be working), Device Driver Kits (DDK). Step 2: Test driver development system To compile a driver, one uses “build.exe” program from DDK. …

To get a display we have to add a component called video adapter with the motherboard. Hardware engineers sometimes call this video adapter as video card. On the video card we can see a group of video RAM chips. The video card may have upto 8MB in board, but most of them are used by …
Normally nobody uses PC/XT (8bit) systems, we use AT (16/32/64bit) systems. So I think it is enough to explain the secrets of keyboard in AT systems. In a typical AT system, the microcontroller(8048,6805 type) in the keyboard sends data to the keyboard-controller (8042 type) on the motherboard. Controller found on the motherboard can also send …
Sound programming can be classified as with PC speaker and with sound blaster card. Let’s see sound programming with PC speaker. Almost all systems have PC speaker. People who like to have digitized sound go for MIDI card or sound blaster card. But for normal operations, it is enough to have PC speaker. Programming PIT …
Terminate and Stay Resident (TSR) is a system call in DOS operating systems that returned control to the system as if the program had quit, but kept the program in memory. Many software vendors use the call to create the appearance of multitasking, by transferring control back to the terminated program on automatic or externally-generated …
TSR or “Terminate and Stay Resident” Programming is one of the interesting topics in DOS Programming. TSR programs are the one which seems to terminate, but remains resident in memory. So the resident program can be invoked at any time. Few TSR programs are written with the characteristic of TCR (Terminate Continue Running) i.e., TSR …
Operating System is nothing but collection of programs for managing system resources like CPU, memory, storage device etc. Study of the Operating System is one of the vastest areas. This chapter does not deal with the details about Operating System. And in this chapter I would like to show you how OS can be written …
