Hii guys
.....
I am beginner in C++
Can anyone help me?
Don't ask meta questions. In other words, don't ask to ask. Questions like "Does anyone know XYZ?", "Has anyone used XYZ?" or "Can someone help me?" are all considered meta questions because they don't specify what your actual problem is.
These questions give the impression that you want people to approach you and offer their help as if they don't have any other work to do. Now doesn't that expectation make you look like an idiot?
If you have a question ask it directly. You are more likely to get a response that way.

What you need is an IDE and a goal
Tokin
Start with what kind of software would you be interested in making, and reason about how you would approach it

Learn the basic syntax (C is pretty easy), then think of a problem and try to solve it using C.

Go through the malloc-free hell. Then read up on Arenas and try implementing better data structures.

I think on modern operating systems a lot many things are quite optimised, not sure if malloc is that bad at beginner level

Very few people are rigorous enough to keep track of allocated memory as they begin working with C
Tokin
Fair

Tbf, malloc free is fine for small projects. You separate out the state handling from rest of the code. But it becomes a headache when u work with code other people have written, they might have another idea and try something else.

I created a app that uses hashmap.c
There are 2 inputs that's coming straight from user input using fgets and are saved in hashmap
But the problem is, all names of map items are pointing to one pointer and with repeating input method, all item.names change to last one entered.
How do I fix this problem ?

then convert this to svg via graphviz as graph for example (with some modifications, eg only first line of WinAPI shown). I will draw edges from each address and merge that have only one following address as block (so I can easily edintify loop dependencies and reasons that lead to some API just by quick look)

do you have source code or something? i'd like to take a look at the source plz

*( ( DWORD * )&zHAi15.pHUD_GetStudioModelInterface ) = *( ( DWORD * )( *( ( DWORD * )&ClientFunc_ADDR ) + 0x9C ) );
it looks pretty much like decompiled code. you're unlikely to use pointer displacement instead of array-like indexing. 0x9C also looks strange, it's likely an offset of struct field

Very few people are rigorous enough to keep track of allocated memory as they begin working with C
May be an ignorant question, but shouldn't tools like Valgrind track all the memory leaks in 99% of personal project cases?
I would not dare to say anything about company-size products, cause I never worked in such a thing, so I don't know how these tools behave in such products

I know that it stills one more tool to learn and master, but helped me a lot to fix memory leaks in C projects

It is a fine question, and the short answer is yes. The long answer now:
Sometimes tracking the lifetime of things in complex applications can be non trivial, or even just plain impossible without some mechanisms to manage the resources (not just memory). Reference counters, concurrent reference counters, semaphores, garbage collections... all these tools often need to be leveraged and managed, and with C said management is very explicit, yet easy to forget and hard to remember.
This is even more complicated with data-structures that may be heavily self-referential, graphs, graphs made of handles to data in another system....

These are ways you can improve the odds of someone wanting to help you.
Be considerate when posting questions.
• Use a search engine to check if anyone else had the same question as yours before asking. Stackoverflow is your friend.
• Be straight to the point (do not ask to ask.)
• Be specific, include as many details as you can.
• Show what you've tried to solve the problem
• We don't care if anything is "urgent" or "important" - wait patiently for someone to reply.
• In addition, please check this site to learn how to ask questions in a public forum.
It's good style to limit the amount of messages you send to a public forum; put effort into 1 message, rather than sending many of them, and edit messages to fix errors or to include more information.

When asking a question about a problem caused by your code, you will get much better answers if you provide code people can use to reproduce the problem. That code should be…
…Minimal – Use as little code as possible that still produces the same problem
…Complete – Provide all parts needed to reproduce the problem in the question itself
…Verifiable – Test the code you're about to provide to make sure it reproduces the problem
