A new way to start programming

Fri, 17 May 2013 16:32:33 -0700

Hey fellow programmers,

I am trying to make a game that will teach the player about the basics of C++ programming. I just finished my first very early prototype and I would really love if you would try it and give me some feedback. I think it could be awesome with a game teaching programming so that more people might get interested in the beauty of programming. My goal is to make this to a full game and of course it will be free for everyone to use.

In general I am interested in making the process in to programming much easier. This will probably result in a webpage with the game and a lot of informations
about how and what you need to start.

I hope you will help me in the making of a new way to introduce programming for beginners.

Thanks in advance

Jan :)

Game can be found on www.sqdejan.com

C++ beginner, help for school project

Sat, 11 May 2013 02:55:41 -0700

Hello there!

(I know that nobody want to make full new code for another people, but this is all about it, please continue reading)

I am having trouble in school with some basic and easy (not for me) C++ programming.
If you could help me, I need codes for these programs to pass a high school grade. I study IT school, but I study multimedia and presentation, but they want basic programming too and I have no idea what to do with it.

Thanks for any help guys!

Create a program, which determines every prime number in interval <1;100> and then print to screen:
Prime numbers in range 1 – 100
number of prime numbers: NN
prime numbers: N N N N N N N N … N

http://prntscr.com/14dmw1 (this is printscreen for another project, by operator I mean + - * /)

Create program, which declarates field formed by matrix named OKTO[8;8]. Matrix’s elements will be saved to file named OKTO_DATA, from element 1,1 to 8,8 where 1,1 to 1,8 is one entry.
For calculation value of elements you have to apply I+1 is double of I.

I beg anyone who can help me to help me, I know really nothing about programming, so I cant discuss this
any help will save my pass to another year of high school, I would be very very very thankfull if anyone helps.
PS: sorry for grammar or any english mistakes, it isnt my native language.

Re: Card Shuffling Program.

Fri, 12 Apr 2013 23:40:56 -0700

I may have just asked for the same thing twice...
Maybe all I'd need is for the program to roll eventually until it finally got one where none were replaced. And displayed the results.

Card Shuffling Program.

Fri, 12 Apr 2013 23:27:19 -0700

I have no idea where to put this.
I was wondering how hard it would be to make a card shuffling program.
I want it to be truly randomized.
Here's a quick example for a 5 card deck:

There are 5 slots so:

[ 1 ] [ 2 ] [ 3 ] [ 4 ] [ 5 ]

and 5 cards:

[ A ] [ B ] [ C ] [ D ] [ E ]

and the true randomization im thinking about would go like this:

A Random number between 1 and 5 is generated for card A, this will be it's slot. And so on for B,C,D and E.

What common sense would say is that A gets a chance at 5 slots and B gets a chance at 4 slots and C,3 etc.

But to me that's not true randomization.

I want a program that shuffles it this way. A,B,C,D and E. Get the same chance at the same slot. It may end up like this:

[ 1A ] [ 2E ] [ 3 ] [ 4D ] [ 5 ] - with B and C being replaced. And being left to the side so to speak with no slot. Because they were replaced.

But this would be stage 1 of the shuffle. Next a number would have to be assigned to A,E and D. 1 for the number of times it successfully had a chance of entering the deck without being replaced.

Next E,D,C,B and A would be rolled again in that order and it would say end up perfect like this, so to speak:

[ 1D ] [ 2A ] [ 3C ] [ 4B ] [ 5E ]

The program would then assign the number to the cards again. A-2 B-1 C-1 D-2 E-2.

This is where the real randomization I want takes place. Since A,D and E have now entered the deck twice succesfully. The process has to be repeated until each card has finally had the exact same number of successful deck entries. Reversing "Roll" order each time. For up to a 150 card deck.

How would one go about doing this and would it be difficult? If that would take too long to load I would understand. The number of times it would have to rinse and repeat would be astronomical.

If that were the case then a simple "Each card gets an equal roll at a spot until finally it rolls each card into its own slot" would be fine.

How would I go about doing 1 or the other?
And what are your opinions on this?
