Tower of Hanoi - 7 - c sharp

Tower of Hanoi in c#

(Console application)

.

Long time ago, for the first time, I came to know about 'Tower of Hanoi' puzzle game through a book on 'C/Turbo C' and another book on 'Data structure'. Both these books were in our course and both books were very good.

.

.

Turbo C's that book was and still is . The Waite Group's Turbo C Programming for the PC By (Robert Lafore)

.

.

Data Structure's that book was and still is . Schaum's Outline of THEORY AND PROBLEMS of DATA STRUCTURES Seymour Lipschutz, Ph.D McGRAW-Hill BOOK COMPANY

.

.

In 'C/Turbo C' book there was an example program for playing 'Tower of Hanoi' puzzle game  (Chapter #: 16, Chapter name: C++ and Object-Oriented Programming, Section: Towers of Hanoi) and in 'Data structure' book there  were 2 example algorithms for solving 'Tower of Hanoi' puzzle game (Chapter #: 6, Chapter name: STACKS, QUEUES, RECURSION, Section: 6.7 - TOWERS OF HANOI).

As far as i remember now, then I wrote both examples in 'Turbo C' and enjoyed playing with game as well as with code. That code was simple but good for 'C/Turbo C' learning level. Then time fast forwarded for around a  decade and this time I made 'Tower of Hanoi' puzzle  game in 'HTML / JScript' using beautiful and solid FrontPage. This time Game environment was much advance then before and more colorful also.

Again time fast forwarded for around a decade and this time in memory of my last efforts for 'Tower of Hanoi' I decided to re-make that puzzle game in c#. Because I was making this version in memory of last 2 efforts plus more so this time I made it as (a) 'Console application' and (b) 'Windows Forms application'.

Here in this post, in the following paragraphs, I am sharing 'Console application' version of 'Tower of Hanoi' puzzle game made by me in c#.

[Note] During making screen shots of 'TowerOfHanoi_07' and adding water marks in those images I came across a small problem. That problem was that my water marks were in color and they were not looking good to me on black background. So to solve that problem I made another win-forms application in c# for changing any/all colors in water mark image to white color. Water marks in images in this post are result of that application.

New style of meeting room

New style of meeting room (A meeting room based on school class room) . When, a few decades ago, I first time entered meeting room with a long table and a lot of chairs beside/around it, I was amazed. After that I saw that type of meeting room a lot of times but only on TV. Every time I saw that kind of room on tv I noticed a problem. And that problem was that in almost all photos or videos meeting members sitting beside table were trying to bend forward or backward to get a better view of the object of interest (either main person of meeting sitting on one of narrow sides of table or some projector screen placed on other side). Therefore this problem was mainly responsible for making it difficult for meeting members sitting on chairs farther than their chair from object of interest (either main person of meeting or some projector screen) to have a proper view of main person of meeting. In some other situation meeting members were seen simply looking at the person sitting on the opposite side of the table "Some times having view of their dreams". . So I started to think on that problem from that time. . At start idea was to have a meeting room like a simple school class room. With main person of meeting, with his helpers, sitting on one side of room were teacher sit/stand and other meeting members sitting on other side like students of class. But a problem of this arrangement was how to make perfect arrangement for both groups. So that irrespective of number of members in both group meeting room serve it's purpose correctly. For example if room's total capacity is 100 person and if there are (a) 50/50 (b) 10/90 (c) 90/10 (d) 'n/m' members in both groups. Than how can room serve it’s purpose without major rearrangement of seats etc. . Now I do not know how and when but I did make an idea to solve that problem. May be my brain kept thinking and mixed different things together. . So I reached on an idea of a meeting-room with wall-to-wall and floor-to-ceiling mirror installed on it's one wall (Front wall). And all seats installed in front of this wall on stair like floor, so that members sitting on any seat can have proper view of the front wall. In this arrangement all persons involved in meeting will be able to see any other member during meeting without any problem. . And after some time, may be years, that idea improved. In this idea simple mirror was replaced with special kind of mirror called screen now, opaque from inside of meeting room and transparent from other/opposite side of screen. From inside meeting room this screen will act like a TV/cinema like screen. On other side will be another room with camera, computers and other useful gadgets. It will be up to meeting members to view themselves on screen like in previous version or view some presentation or some video or mix of these all in any combination or view nothing at all on screen. . If there are any mistakes then I will surely remove them whenever found. .
