Logo Package Drawing Using C (CODE)
This is a logo package by which you can draw different object using
keyboard. This program uses number of colour patterns and object movement
at the time drawing. This logo manages the cicle by which you can move into
different directions. Also can increase or decrease the radious of the circle
as you wish.
Code is given below.

Bricks "computer game" In C (CODE)
Bricks is a computer game which is played by the single player at a time. In this game a four layer of
bricks is there and you have to knock out the brick by the ball to get the point.For each knock you get 5 points.
You have maximum of four balls and each time you lose the ball 10 marks are deducted from your score.
You have to catch the ball on the paddle which is appearing on the bottom on the screen and if you will not able the catch the ball on the paddle you lose the ball. For moving the paddle use left and right arrow key.
As the ball and paddle are to be moved throughtout the game, we first store their images
in the memory using malloc() function which is used to allocate the memory.After this , the image at new coordinates is set erasing the previous location. When the ball reaches to the boundary it will pushed inside.

Major Project In C (CODE)
In this project the main menu provide the option for different
demonstration. The item from the main menu can be selected by using the enter key or by pressing the
hotkey which is represented by the bold character. The getoutput() function
manage the movement of the cursor and selection of the menu item this function
also use getkey() function to to find which key has been press by the user.
The Showmenu() function is used to displays the menu in box drawn by menubox()
available in the "intro.h".

Solar Power Satellites
The new millennium has introduced increased pressure for finding new renewable energy sources. The exponential increase in population has led to the global crisis such as global warming, environmental pollution and change and rapid decrease of fossil reservoirs.
Stealth Fighter (PPT Notes)
Definition
Stealth means 'low observable'. The very basic idea of Stealth Technology in the military is to 'blend' in with the background. The quest for a stealthy plane actually began more than 50 years ago during World War II when RADAR was first used as an early warning system against fleets of bombers. As a result of that quest, the Stealth Technology evolved. Stealth Technology is used in the construction of mobile military systems such as aircrafts and ships to significantly reduce their detection by enemy, primarily by an enemy RADAR. The way most airplane identification works is by constantly bombarding airspace with a RADAR signal.
When a plane flies into the path of the RADAR, a signal bounces back to a sensor that determines the size and location of the plane. Other methods focus on measuring acoustic (sound) disturbances, visual contact, and infrared (heat) signatures. Stealth technologies work by reducing or eliminating these telltale signals. Panels on planes are angled so that radar is scattered and no signal returns. Planes are also covered in a layer of absorbent materials that reduce any other signature the plane might leave. Shape also has a lot to do with the `invisibility' of stealth planes. Extreme aerodynamics keeps air turbulence to a minimum and cut down on flying noise. Special low-noise engines are contained inside the body of the plane. Hot fumes are then capable of being mixed with cool air before leaving the plane. This fools heat sensors on the ground. This also keeps heat seeking missiles from getting any sort of a lock on their targets.
Stealth properties give it the unique ability to penetrate an enemy's most sophisticated defenses and threaten its most valued and heavily defended targets. At a cost of $2 billion each, stealth bombers are not yet available worldwide, but military forces around the world will soon begin to attempt to mimic some of the key features of stealth planes, making the skies much more dangerous.
HISTORY OF STEALTH AIRCRAFT
With the increasing use of early warning detection devices such as radar by militaries around the world in the 1930's the United States began to research and develop aircraft that would be undetectable to radar detection systems. The first documented stealth prototype was built out of two layers of plywood glued together with a core of glue and sawdust. This prototype's surface was coated with charcoal to absorb radar signals from being reflected back to the source, which is how radar detection systems detect items in the air.
Jack Northrop built a flying wing in the 1940's. His plane was the first wave of stealth aircraft that actually flew. The aircraft proved to be highly unstable and hard to fly due to design flaws. The United States initially orders 170 of these aircraft from Northrop but cancelled the order after finding that the plane had stability Flaws. Then in 1964, SR-71 the first Stealth airplane launched. It is well known as 'black bird'. It is a jet black bomber with slanted surfaces. This aircraft was built to fly high and fast to be able to bypass radar by its altitude and speed.
HOW DOES STEALTH TECHNOLOGY WORK?
The idea is for the radar antenna to send out a burst of radio energy, which is then reflected back by any object it happens to encounter. The radar antenna measures the time it takes for the reflection to arrive, and with that information can tell how far away the object is. The metal body of an airplane is very good at reflecting radar signals, and this makes it easy to find and track airplanes with radar equipment.
The goal of stealth technology is to make an airplane invisible to radar. There are two different ways to create invisibility: The airplane can be shaped so that any radar signals it reflects are reflected away from the radar equipment. The airplane can be covered in materials that absorb radar signals.

BIOS Beep Codes
When a computer is first turned on, or rebooted, its BIOS performs a power-on self test (POST) to test the system's hardware, checking to make sure that all of the system's hardware components are working properly. Under normal circumstances, the POST will display an error message; however, if the BIOS detects an error before it can access the video card, or if there is a problem with the video card, it will produce a series of beeps, and the pattern of the beeps indicates what kind of problem the BIOS has detected.
