| | This program displays a simple analog clock to show the current system time. Uses a Hand class to create objects - hour, minute and seconds hands.The 'hands' are just straight lines, and two circles make the 'frame' of the clock. Compiles correctly on TurboC++ v3.0 |
 | This is a program for Encryption and Decryption This program uses the Simple Data Encryption Standard (SDES) Algorithm. This Algo takes 8-bits of plaintext at a time and produces 8-bits of ciphertext. It uses 10-bits of key for Encryption and Decryption.  |
| | Quite a while ago, I made [URL="http://www.daniweb.com/code/snippet217147.html"][B]this[/B][/URL] snippet. This code is basically the same, except that it adds animation. This method of blitting is very fast assuming you don't use a surface that's too large. On a 500 x 500 surface, I managed 350fps using only 0-1% of the cpu. … |
| | This is a program I just recently completed for a computer science course. Given a 2D grid, where every path between two gridpoints has a weight (path length) associated with it, this program computes the shortest path from (1,1) to (m,n). You are only allowed to move up and to … |

| | This AVI file player has some nice features like adjusting size and speed. The program uses the standard MSvfw32.lib (called libmsvfw32.a in the DevCPP lib directory). Another example of using BCX to translate to C code and modify to something Dev-C++ can handle. Enjoy!!! |
| | Code will check whether the number entered is integer or not. [inlinecode]ignore[/inlinecode] extracts characters from the input sequence and discards them. The extraction ends when max characters have been extracted and discarded or when the character delim(\n) is found, whichever comes first. In the latter case, the delim character itself … |

| | I have add the two functions the add and subtract I have to now add the multiply and divsion functions can someone help |
| | An example how to plot the function y = sin(x) using the WinApi function SetPixel(). The plot is centered along a line at pixel y = 200. Add an x-axis and a couple of tickmarks and it could look impressive. |
| | Factorials get large very rapidly. The factorial of 13 is !13 = 1*2*3*4*5*6*7*8*9*10*11*12*13 = 6227020800. This number already exceeds the unsigned long integer, and gets into the real money as the politicians say! This program uses an array of characters to store the factorial as a numeric string. Go ahead, … |

| | Here is a small--complete--program that includes a sub-routine that inputs two matrices and then multiplies them. Notes: * 1) I happen to like taking input from a text file. It eliminates the need to type input from the console, especially when debugging, it prevents the possibility of making typos. * … |
