This is yet another example of reversing a string. This version modifies the original, reversing the string in place.

This problem is a typical homework question. The code presented here may contain some elements that may be a little "ahead of the game" in coursework, but it presents some of the basic elements that might be used in such an exercise. (View Snippet)
This is a bit more tough than it sounds. well some one gave me this problem and I found this tricky not until I used recursion. (View Snippet)
Many of the code samples on the internet are written in Turbo C. The clrscr() function litters these samples, and even to this day people want to wipe your screen. You can use system("CLS"), but that uses a DOS command. DOS commands are with us only at the whim of William the Mighty. Here is... (View Snippet)
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. (View Snippet)

Text fragment extractor (usage: fragment /pattern/ ] 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, then... (View Snippet)
