Uh lambdas? Idk if I see them

Uh lambdas? Idk if I see them
I think I just got some "brain-illusion". I studied python for 3 months, leave it for 6 XD (Using sololearn).
Anyway, what I want to know is if it is good (For any purpose) to use conditional operator or focus on if...else statement
NB: I only remember that lamba function were shorter than normal function XD

Ahh... ok.
What if I use gitlab?

Hey community.
I'm new to programming and I would like you guys to revise my code.
PRECISION: I DON'T NEED HELP, i just want you to check it out.
I'm fan of lambda function in python, and I try to use in C in order to reduce the code-making time.
Just need some suggestions, if I should focus on if...else, or use conditional operator ("?") as much as I can (Specially for small codes)
Yeah... Idk.... Maybe you can see asm what it generates

If you want use lambdas, use C++ :)
Not interested in learning C++ for the moment.
Just wanted to know if conditional operator was a wise choice for using as a "default-mode" while not having a non-fatal logical error

If you want to know what's the difference, you can look at the compiled asm

Where should I check for it? (I'm actually using DCoder, an Android App).

Idk dcoder...

I think that GCC and clang supports it

1) conditional operator is just writing hard to read code, unless the expressions are simple enough (in this case they are).
2) this has nothing to do with lambdas

1) Ok, I will think about it for my next code.
2) I got some confusion, I admit it. XD

I just read what was lambda in python. It's for creating functions without a name. XD
Worst, in my code I only use main function. I don't know how I considered a statement "puts" as a function XD.
Well, fruit of ignorance

What really happens when you don't write anything after the "return" keyword in a function?
Indolent
What really is the "return" keyword?
Abhi
Return keyword is used to end the program/ function execution
Abhi
Even if u didn't write return nothing happens

So... you are not forced to do 'main(void)' in order to not use return?
Anonymous

Return keyword returns the control back to the caller
Anonymous
When you execute a C program you're actually jumping to a label named main and transferring control to it
Anonymous
Whatever code is at the place referenced by the label is run
Anonymous
Now that control was transferred to your program it must be returned to your OS
Anonymous
Return returns control back to the caller
Anonymous
For non void functions return needs an argument. The caller can read this value passed by return and do whatever with it

guys when I link libs which placed in specific location I cant execute program , it gives error that says me sfml-graphics-2.dll has not found but when I place libs and makefile with same folder it compiles and runs successfully . Where am I wrong , Im so newbie sorry at all

I don't use Windows, but I thought you needed anti-slashes in those paths?

applications in most operating systems will default to the current directory for loading dependencies then look in the environment path
Linux is a lot easier

In windows you have to put DLLs along the executables.
In Linux you can put libs anywhere and sat the path to the folder in PATH variable I am not sure if you can do that in windows or not

How to change the adbd root directory. Means when I am using adb shell, directly it is getting access from root directory, but I want to protect it and I will give a particular directory path if the user will adb push to that directory only it should work?

Which is the best Linux distro for coding / development ?
I like the Arch based ones, great documentation
Đỗ
Arch so robust. I tried to tinker on Mint and Fedora for code QT_C and Ubuntu for Android. It's so good
If yo want to dev Web or host your web service, RedHAt or cenOS is a good options

Have u try to create a symlink or alias to your root dir? Instead work directly on it, you only access it via alias, for e.g: read from it but "ls" return nothing

No I didn't create any symlink. I want like usb protection. Basically nobody should able to access anything. If the user wants to write any file, they should use that particular directory and even if there will be a unlock process for that user. If they will try to do adb push to any directory or root directory it should denied

Manjaro is the easy way to do Arch
the repository is led by a few months give you some safety

What is the meaning of Node *prev ?
Alex
pointer to previous node, like "next" is pointer to next
Indolent
I know that but why this Node before it means?
Alex
do you know what is linked list?
Indolent
Yes sir.

I can`t understand your question in this case

I'll have to learn OOPS. It's just super boring.

Hello! Why can I get stack overflow in malloc() and how to avoid that?
Pavel
I call malloc many times in recursion (Depth-First Traversal)

U can't get stack overflow using malloc. malloc is used to allocate space on heap.

void DFS(struct DFS_arguments *arguments) {
...
for ([next_x, next_y] : moves) {
if (!arguments->used[next_x][next_y]) {
arguments->used[next_x][next_y] = 1;
struct DFS_arguments *new_arguments = malloc(sizeof(struct DFS_arguments)));
new_arguments->x = new_x;
new_arguments->y = new_y;
DFS(new_arguments);
free(new_arguments);
}

Some pseudo-code to understand, what am I doing
Pavel
Recursion depth is around 30000, size of DFS_arguments is less than 128 bytes

Stack size is about 1MiB by default

Yeah, I was wrong in my calculations, it was a regular stack overflow, thank you
