C / C++ / C# C / C++ / C# Fundamentals Tips & Tools Going Pro From David Bolton, your Guide to C / C++ / C# There's still time to get your entries in for Challenge 33 as I won't be marking it until next Monday, April 5. Challenge 34 has now been published and asks you to move numbers on a 10 x 10 grid to form a straight line. Details below. This week, starting today I'm publishing "Ways to make money programming", a blog post each day for a week on a different aspect of programming for money. If I've missed your favorite tell me! Email to cplus.guide@about.com. Have a profitable week! Oolite - Open Source Elite Clone After mentioning NAEV last week, I came across OOlite which is a cross platform clone of the original Elite. It's accurate down to the ships, the commander's name and even the Blue Danube music! If you don't "get" the ship docking to the theme of the Blue Danube, watch the film 2001 if you get a chance. it's a genuine Sci-Fi film cliche! Using open source components such as SDL, zlib, jpeg,libpng, libogg etc, the binaries plus resources only add up to 30MB. If you want to try playing with the sources of a pretty simple game this is a good starting point. Link to C Games Code Library Programming Challenge 34 - Complete Straight Lines Just a few days to get your entry for Challenge 33 in with a slightly stretched deadline now of April 5th as it's a holiday weekend. Meanwhile the new challenge is live and it's about a simple board board game on a 10 x 10 grid. Each cell has a random digit 0-3 and there are 25 of each digit. After rolling a dice you get to make 1-4 moves swapping the numbers between adjacent cells either diagonally or laterally (horizontal or vertical) according to the dice roll. The point is to make the moves so you end up with a straight line of 10 digits all the same (which digit doesn't matter) running vertically, horizontally or diagonally. That's it. Full instructions in the challenge below. Link to Programming Challenge Thirty Four Compete a Straight Line Link to Programming Challenge Thirty Three Evaluate Expressions OpenGL Reaches 4.0 + OpenTK Currently only supported by one set of graphics cards, OpenGL reached 4.0 about two weeks ago. It's one of a set of open APIs that are published by the Khronos Group, a consortium of about 100 member groups. Given my past Windows centric view of the world, I've been more into the DirectX world as espoused by Microsoft but with non Microsoft mobile devices such as the iPhone having an embedded version of OpenGL (OpenGL ES), I've been looking more in this direction. OpenGL lets you render graphic scenes in code. There's also a high level shading language GLSL that is C/C++ like for coding shaders. Microsoft have their own HLSL language for Direct3D. If you're a .NET or Mono C# developer interested in OpenGL, OpenGL ES, OpenCL (Computation) and OpenAL (Audio Library) there is an open source C# toolkit that you might find interesting. It's currently at release candidate 1 so not far off the final version 1.0 release. It also includes a lot of extra stuff such as GameWindow, GlWidgets, 32 and 64 bit, 3D math toolkit, and several APIs for Input and Display.

About C / C++ / C#: Interesting Algorithm - Darts Scoring

If you can't see this email, click here

C / C++ / C# C / C++ / C# Fundamentals Tips & Tools Going Pro From David Bolton, your Guide to C / C++ / C# Well I'm back from my 7 day vacation in the Middle East and raring to go. I'm pleased to announce the first iPhone tutorial "My First iPhone App" has now been published, complete with source code. The details are below. BTW, if you're new to Mac from Windows, you can gain enormous productivity simply by going into System Preferences/Mouse and enabling the secondary button for all those right click menus etc. Have a Great Week! My First iPhone App Tutorial Published It's a very simple App but I'm pleased with it. There's quite a learning curve towards mastery of Xcode, Objective-C, the UIKit and other frameworks so this is just the first step on a long journey and a number of tutorials to follow. The screen shots are from the simulator running on my Mac Mini. The source code and the graphic used are included in the tutorial as a download. I'll be publishing the next C# tutorial in a few days then working on the next iPhone tutorial on property, views and memory management. Hopefully by then the iPad will be out. Remember that all iPhone tutorials also apply to iPod Touch and iPad though inevitably there will be iPad specific tutorials. I've created a new section for the iPhone tutorials below. Oh and before anyone asks, I'm sorry but I'm not available for programming your project! Link to iPhone Tutorials Darts Problem Revisisted Reader Ben Jackson wrote an interesting email on calculating the darts scoring problem (lowest score that you can't get with three darts) and included a 170 line C++ program to solve it. With his permission, I've included it here as a download. It uses three methods to compute which scores are impossible for the general case of throwing D darts at a dart board with W wedges and including doubles and trebles. 0, (a miss), 25 and 50 can be switched on via some macros. I've also added it as a permanent link below. Link to C++ Code Library NAEV - Open Source Space Trading Game in C Back in 1984 the big game release was Elite, a space trading and combat game that well deserved its accolades and gave it a place in computer gaming history. I played it a lot on the BBC so have a soft spot for this type of game. It's not the most popular game genre but the space trading and combat genre has had a few well known games such as Wing Commander:Privateer, Escape Velocity, and Elite in various other versions. In fact 26 years on from the original, Elite 4 is currently under development by a team including one of the original developers David Braben. But as always its the open source versions that interest me. Written in C, with scripting in Lua, NAEV is an open source version of Escape Velocity and is cross-platform for Windows, Mac and Linux. The initials are Not Another Escape Velocity. There's also a Wikipedia article about the game though curiously that is marked for deletion. Link to C Games Code Library Never Programmed Before?
