 | This program uses WinApi function SetPixel() to plot math functions y = sin(x) and y = cos(x) and y = sin(x)*cos(x) along a y-axis centered on the console screen. Make sure that gdi32.lib is included in the libraries to be linked. |
 | A fairly complete implementation to provide another perspective on a seemingly simple program.  |
 | A very rudimentary more, press enter to view next screenful of text, like with print command in ed text editor. |
| | Similar to cat in unix textutils. You can actually edit files with these. Remember that ctrl-z sends end-of-file in windows, and ctrl-d in linux.  |
| | Text fragment extractor (usage: fragment /pattern/[n] [/pattern/[n]] file), similar to the print command in ed and vi, with pattern range. If the second pattern is omitted, prints to the end of file. Use quotation marks when there are spaces in the argument. Finds the first pattern, then the second pattern, … |
| | Unlike a balanced skip list, a probabilistic skip list uses random numbers to determine the height of each node rather than deterministic logic. The only real advantage of using a linked structure instead of an array based structure is in code maintainability. |
| | Array based skip lists are a pain to work with. They are error prone and difficult to follow. Worse, they are difficult to extend so that the data structure is deterministic rather than probabilistic (a desirable property). The following implementation uses a linked structure instead of arrays for the levels. |
 | In [url=http://www.daniweb.com/code/snippet149.html]Part 2[/url], you may have noticed that the bits representing the [i]value[/i] of an [font=courier new]unsigned int[/font] did not appear to match the bits representing the [i]object[/i]. This is because of the [i][url=http://en.wikipedia.org/wiki/Endianness]endianness[/url][/i] of my implementation. When it comes to displaying the bits of objects that take more space … |
| | In [url=http://www.daniweb.com/code/snippet148.html]Part 1[/url], I chose [font=courier new]unsigned int[/font] as the type to use for displaying the bits of a value. The same general procedure can be done with other types as well. The biggest issue really is the expression which generates the most significant bit, for which there are a … |
| | It is often instructive to display the bits of a value. (This is similar to 'converting' an integer to binary.) The way I have done this in this snippet is to start at the most significant bit and work your way through all the rest of the bits. (Continued in … |
| | This is a very common task for a beginner programmer. Unfortunately many beginners do not seem to understand the question. First, know that binary, decimal, octal, hexadecimal, and others are simply [i]representations[/i] of values. The value of 123 (decimal) still has the same [i]value[/i] if it represented in hexadecimal (7B), … |
| | Let's expand the decimal to binary converter to include, amongst others, octal and hexadecimal conversions. Also shows how to exert some input control. Simple stuff! |
| | Get simple information like serial number, bytes/sector, sectors/cluster, free and total disk space of your hard drive using Windows API calls. |
| | This program finds the solution of system of simulataneous equation Using GAUSS SEIDEL METHOD. This method is very popural among the students who studies Numerical Techniques.Though this program cant find the solution of every equations,it is widely used.This can only found the solutions of those equations which are Digonally dominant. |
| | What is so easy to do in HTML gets quite involved in C. Once you learn to look past the standard GUI overhead it becomes more obvious. This example shows the effect of the mouse cursor moving across a label by changing foreground and background colors. |
| | This program shows how to display a JPEG (also GIF,BMP,WMF etc.) image using some Windows Graphical User Interface C code. The program uses the uuid.lib file that comes with many C compilers. |
| | Use a Windows API call to add some color to your text output. A rewrite of an earlier C++ snippet for the C crowd. |
| | The continued fraction expansion gives us the answer to life's most persistent questions, like what is sin(x) or even tanh(x). This surprisingly short code allows you to estimate SIN, COS, TAN, EXP, SINH, COSH and TANH fairly accurately. Careful, this code is not for the usual TV crowd! You should …  |
| | This quicksort implements the basic recursive algorithm with three improvements. The first improvement is choosing the pivot based on the median of three values in the list to be sorted. This minimizes the chances of a worst case scenario. The second improvement speeds up the algorithm by termination when subfiles … |
| | Adding this because it took literally an hour of searching before I found a code sample using fscanf that read more than just the first line of a file. This code assumes you're reading a file line by line that has the angle (int) followed by the Sine Value of … |
