| | My first experience with pointers. Learned how to spell a string foreward and backward using pointers. I hope you can learn too! |
| | A simple experiment with the ever so popular Mandelbrot fractal graphics, call it mathematical art, nice to look at. This set of experiments loops through a number of colors to make the whole thing more exciting. |
| | I was looking for a somewhat meaningful and interesting example to explain the Python class to beginners. A room full of multilingual students makes this phrase translator a good choice. You can experiment with it and add more languages and phrases. |
| | A common way to represent an inventory is with a list of tuples. Each tuple represents the item name and the item count. You can sort this inventory list by item name or item count. Here is an example to pick a sort key. It's your summer job to run … |
| | This code uses field level validation to check for data in fields in an Access form, and instead of using message boxes (as the "Validation Rule" and "Validation Text" properties of a field (in the table design window) do, it turns the associated label and control (textbox/listbox/combobox) background color to … |
| | 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 … |
| | Quick and dirty way to change your console program colors using DOS command "Color BackgroundForeground" where Background is hex 0 = black to F = white, dito for Foreground. |
| | Using wxPython and the Boa Constructor, a VB/Delphi like IDE and Visual Builder, this little calculator was a breeze to make. Boa did 90% of the code generation, and I simply added code to each button click event to make the calculations work. I wish every project would go that … |
| | The WinBGI package allows you to do some of the Borland BGI graphics in a specially created window form. So don't throw out the old Borland manuals, you can still use them to do some fancy graphing! Yes, you can gotoxy() again! This code was modified for Dev-C++, a real … |
| | There are some pretty fancy things you can do with strings in Python. You can append, convert, justify, join, split, slice, and list selected files of a folder. I just give you a small sample here. |

| | The Standard Template Library (STL) vector is tempting. The burden of dimensioning an array is removed, and there are many wonderful functions to explore. The learning curve is a little steep, it will make your head swell, but in the end it's all worthwhile. Take a look at some of … |
| | 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! |
| | Another experiment with the Standard Template Library (STL). This time we are taking a look at map. Map is a Sorted Pair Associative Container (a mouthful). The pair is -- const Key, Data --, where Key has to be unique. It is Key that is sorted. In this code sample … |
 | Insertion sort, Selection sort, Bubble sort, Shell sort, Quicksort, and Heapsot. All optimized and ready to be experimented with. This is the framework for a Java application that speed tests various sorting algorithms (because there's usually little need to write one's own in production programs). Several popular algorithms were left …  |
| | 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 … |
