Discussion Overview

The discussion revolves around learning C++, specifically focusing on matrix inversion and related programming tasks. Participants express a desire to share knowledge and resources, while also addressing the challenges faced by beginners in understanding C++ concepts and file operations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related
  • Debate/contested

Main Points Raised

  • Some participants encourage posting questions publicly to facilitate learning for others, suggesting that this approach benefits the community.
  • One participant offers to help with basic C++ concepts and directs others to their website for additional resources.
  • Another participant warns that working with complex file formats like GIF may be challenging for beginners and suggests starting with simpler tasks.
  • There is a suggestion to work with bitmaps before attempting GIFs, emphasizing the need to learn file operations in C/C++ first.
  • One participant expresses confidence in their C knowledge but seeks clarification on the relevance of bitmaps to their inquiry about GIFs.
  • A request is made for assistance in writing a Visual C++ program for matrix inversion, indicating a specific programming task of interest.

Areas of Agreement / Disagreement

Participants generally agree on the importance of starting with foundational concepts before tackling more complex programming tasks. However, there are differing opinions on the best approach to learning and the relevance of certain topics, such as bitmaps in relation to GIFs.

Contextual Notes

Some participants have varying levels of experience with C and C++, which may influence their perspectives on the complexity of tasks like GIF editing and matrix inversion. The discussion reflects a range of familiarity with programming concepts and resources.

If there is somene hear who knows C++ and is willing to discuss the language in e-mail please let me know. I'm in the learning process and have too many questions to post them. If someone would ejoy such an exchange I'd be grateful. Thanks

If you want, send me a private message (not an e-mail) and I'll answer what I can.
 
If you post here I can answer your questions. Plus it will help others that want to learn too.

Send me an email with your questions and I will, absolutely for free and with no strings attached, refer you to Google.

But that's only because I don't know C++. :wink:

This is what I love about PF. Someone asks a question and 7 people jump up to help answer.

One thing I'd love to work through/understand is the code to write to graphics file.

Hi

I'd be glad to help...I have put up some really basic stuff on my site (www.geocities.com/fsairin/) about C++ but whether or not it helps you depends on your current level of understanding/experience.

Please post the problems you face so that we can help you out...

And of course, google.com is a wonderful way to find out more about C++ resources on the internet.

Cheers
Vivek

If you'd like to edit files of such complex systems as gif and you are in the learning process you are in deep waters man. I've been playing around with c++ for three years now creating games and working in openGL and when i thought about including 3dsmax files I lost it...
From what I can tell of your experience just by reading your posts I think you should start with easier tasks. If you want to learn and not just copy/paste that is. (Which for some reason often seems rather similar :P)

I would work with bitmaps before attempting gifs.
First you need to learn C and/or C++. Then you need to learn file operations with them. Then you can try something like image reading.

I already know C and file operations.

As mentioned above I already know C. I learned it about 14 years ago and programed in it (for work) for 4 years. It's a piece of cake for me to write C code (once I refresh a smidgen). I know a bit of C++. I know enough to do whatever I'd like to do. But the question regarding GIFs was outside the C++ question. If I were to take a wild guess I would say that I want to find the file format, LZW compression algorithms etc.

Someone mentioned bit maps. Why would I need bitmaps. I'm not referring to Visual C++ so why bother with them?

pls help me to write a visual c++ program on matrix inversion (the matrix should be of any order and it may be a sparse one)...
