vector<int> * graph = new vector<int>[nv];
I am not able to add items to graph using this
(graph+v1)->push_back(v2)
I am assuming it is due to (graph+v1) is null.
Is there a better way to declare the array of vectors?
Vlad
Sench
Ok sorry
Vlad
new and containers don't mix
Light
Tried that also
vector<vector<big>> graph(nv, vector<big>());
Light
But it is giving bad_alloc() error
Light
big = long long int
Vlad
nv is what value?
Vlad
Have you initialized it?
Light
int nv;
cin»nv;
vector<vector<int>> graph(nv, vector<int>());
Vlad
Where is the check for input Jonny?
Vlad
What if I enter 'asfasdgsadgasd' into the program?
Vlad
Or -1
Light
okay I think that is the issue. Thanks for the help.

I was actually reading values from a file using cin. I created the file in a wrong location so the file did not exist. But the program was not throwing any error that is is not able to find the file😂. That is why I thought it is reading from the file. But in reality nv contained garbage value.

That's why you should zero initialize your variables and error-check

why you hate VLA?
It's slow and it's dangerous to stack overflow. Even The Linux Creator hate it

Hey sup guys!
About build libs, I know that have 2 type of lib, dynamic and static.
Dynamic (like a .dll) is apart of "client" and is a dependency. Static (like .lib) turns able to compile everything in jus one bin. Nice.
Well, I have a lib but when I use it, the "client" have access (and dependency) on my lib dependencies (lib depends on Boost, client needs too).
I was reading about static link that lib, but don't know if I really understood, can static .lib have all of your dependency on it binary file? Or just dynamic libs?

Sorry, could you clarify that static "(like .lib)" executable ?

Static libraries (like .lib) turns possible to compile everything in just one binary file

Your definition on static executable is wrong then
\Device\NUL
Static executable means embed the library also in the executable, cmiiw
\Device\NUL
For example you pass user32.lib in the MSVC compiler. That doesn't prove it's static

A thread local storage variable is a named identifier that represents different variables in different threads. If you must access a thread local variable from another thread, then you must do it indirectly using pointers. But you have to be careful with the lifetimes and also with synchronisation which both defeat the purpose. So it is not a wise choice
so even if i do it indirectly with pointers, it won't crash will it?
Anonymous

It might crash (Undefined Behavior) on implementations where threads are not allocated in the same address space as that of the process. On such implementations (OpenBSD for example), there is no way to access the thread local variable of one thread from another thread.

Hello community, what projects can I work on as a beginner who has learnt C language. Please

Hello community, what projects can I work on as a beginner who has learnt C language. Please
Depends on how comfortable you are with the language.
I would suggest looking through projects already implemented in the language of your choice and understanding them before you work on projects of your own.
This is a good place to start:

You should ask GPT but since you asked create something related to setting request actually there is a library called libcurl or curl use that and create a simple stract that you can assign to an object to send an http request and return the response in a formatted manner

I am a JavaScript programmer. But I want to learn programming fundamental with C language. Any idea how long will take to learn C language?
Tokir0074
1 months is enough bro..
Adil
Only 1 month? Strange!
Tokir0074
But you have to do lots of practice

Data structures and algorithms are the same across programming languages
What is the goal you're pursuing by learning C?

I think C and Java is best for problem solving. And these are mid level language.

It depends on definition of "learn a language". Learning the syntax of C is pretty fast, learning how to write safe and efficient code with minimal bugs can take a lot of time.

Let’s be honest while C is a lot simpler than C++ learning and correctly using all the concepts like memory management, pointers and algorithms will take a lot of time and a lot of practice. Systems programming in general is hard when you only know JS - it’s a different world

a lot more than js. It's not about the language but about its usage - like system/embedded programming etc (i'm not a C programmer)))
