Gotcha

I seldomly hear about applications with GUI completely written in python

You need not to much worry on great learning curve which is in C++
Avezy
In Web Development maybe with Django

Hello everyone!
I've in plans to learn Pure C (Maybe some C++). Currently, I'm an Android developer. Have good knowledge in Java. Also, I know a bit of Python. I'm using Linux as my main operating system.
I want something fast and simple because the overhead that we have in using Java is pretty big.
I really need advice from people who are working with C, how to learn it better and more practical.
There will be few points and I will really appreciate if you'll share any of your ideas about them.
1. I've heard a lot about that is better to use old C90 standard. Correct me if I'm wrong.
2. I'm interested in writing good quality code from the beginning, so I will appreciate any checkstyles or checkstyle checkers what people use.
3. Also, I have a question about what IDE is better to use. I've used CLion a bit and also used vim but without any additional plugins.
4. Probably I will start my learning by creating some game on SDL (probably second version). If it's a bad idea tell me why.
P.S. Also if you have any information or ideas that are not about something in this list, share them, please. Thank you in advance.
I don't know who told you that old C90 is better, but don't do it. If you want to use C, use C11 (I think it's the last revision). But, if you're doing game development, just use C++, and the latest standar you can (C++17 or even C++20/2a if you want). But please, don't use old revisions of any language, and even less in a new project

Hi
How can i send some value in one dimensional array into two dimensional array? (c++)
Sounds like a job for a loop, I bet.

No, the question is we put 6 value in one array, and send it in [2][3] array.

Maybe nested loops then. 😆
Jeremy
Read values from one array, check counter condition, loop through second array and set values
Jeremy
Unless I've done so much Python that I forget C++ rules.

well you're very very very wrong. yes there are these people who find it cool to hate on new features, but you'll just have to learn to ignore those. also if you're looking for anything game related C++ will likely be better (and for most things C++ would be better, so idk why you want to learn C, which is better than C++ only is select few cases). and for ide just use whatever suits you, CLion will work, so will vim (but some plug-ins would be handy)

Yeah, I want to learn C. Then I realize how quickly something could go wrong with code that doesn't look problematic. It's not such a safe language, unless you learn from your mistakes and don't repeat them. If you can get through C, you can probably make it through most other things, right?

yes

Well, languages are different, they use different concepts on the level of the language (classes, functional objects, coroutines, lazy evaluation). You can use some of such concepts in C as well, but it would be much harder as you need to implement them and be consistent, because there's no compiler to help you with this (because it cares only about C syntax).
Usually, if you know C well, but know only C.. then you know only C.
