[QUOTE=shubhamgore;1231564] why should we have to avoid goto, i have used it here becoz i have learn it yesterday from complete reference (c) [fundamental book for c language], and there was a note, saying that whenever we want to shift control of program over any part of the code, [U]we …

Yes, you can simplify this code - I would suggest to dismiss branching statements in "decode" procedure and make use of static array of LED patterns. Something like: #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAKE_PATTERN(b1, b2, b3, b4, b5) ((b1 << 4) | (b2<<3) | (b3<<2) | (b4<<1) | …

As unofficial rule - all C/C++ macros are written in all caps. Underscores simply helps to improve readability if constant consists from several words. It's possible to name a variable with underscores, but it's uncommon. So if you see all caps symbol with underscores in it - you can be …

Or... use backtracking algorithm => [url]http://en.wikipedia.org/wiki/Backtracking[/url] Main idea- Save each crossroad decision you take in the tuple form [ICODE](COL, ROW, DIRECTION)[/ICODE].

Fill this list until you get into blind alley OR no NEW crossroads are reachable. If so …

Also i want to say that this question is related to compiler design. So i would suggest to learn compiler design/programming in general, before advancing to concrete problem.

[ICODE]write_data(...)[/ICODE] is callback function which will be called every time each new data portion arrives from internet.

Since you didn't write a language in which you want to program - for the beginner i would recommend either [URL="http://love2d.org/"]Lua + Love2D[/URL] OR [URL="http://www.pyglet.org/"]Python + PyGlet[/URL] Happy coding!

I don't think that SQL server (or any other database server) is suited for multiplayer purposes. Usually game devs for multiplayer mode writes it's own server and client.

From the problem description is not clear - Do you want just move 3D model in space or animate different pose ? Ok, I make assumption that you want to animate pose, because you mention different body parts. How to do that just google keywords "mesh deformation" and/or "skinning GPU". …

Indeed CUDA is only for nVidia cards. I suggest better using OpenCL. Also if these calculations is only for computing image transformations- you can try Pixel Shader.

A VERY interesting question ! Thanks for asking such thing :) Both methods are polyalphabetic ciphers. There are some algorithms for polyalphabetic ciphers which computes key size from ciphertext.

recursion is your friend

If number of permutations is not big - simply try to bruteforce. Otherwise try genetic algorithm - it is good for such sort of optimization problems.

Even 64-bit integer is not able to store such big numbers. You will need to store these numbers in array as sequence of digits and write your own addition operation of such big numbers, cause CPU can't add integers bigger than int-64 without loosing precision.

I'm not expert, but will try to answer. Make substitution [ICODE]r=(a+b)a*b[/ICODE] (it will be easier to analyze), then you will get such picture below. So basically 'a' transition is used to make 'ar' transition. Hope that helps.

Or you could achieve practically same thing with backtracking algorithm- [url]http://en.wikipedia.org/wiki/Backtracking[/url] Start from (0,0) Choose next legal node (x,y) If sum_until(x,y) > (3,3) -> advance backwards to previous cell, and choose next legal move.
