If this is true C might never be eliminated. 😅

Assembly is the extra step here. But that can be a good idea for some newly created language to cross compile into C/C++ because C/C++ compilers are damn good at optimizations. Wonder how many languages actually do that.

So, that is why they say: If you can not code it in assembly then it can not be coded. 🤔

Then why people are not coding modern applications using just assembly language then?! 🤔 There are some valid reasons: 1. Not portable. Write once, rewrite forever. 2. Development time. As an example, writing a simple mathematical equation in a high level language takes some seconds, doing the same in assembly you will take minutes. 3. Bug prone. The slightest detail you get wrong and your code will not run as intended, it will assemble fine though. And these are just a few (valid) reasons most people are not writing modern applications purely in assembly language nowadays. 🙂

why not mov ? writing to memory to read from it again seems inefficient. the isa seems inconsistent as well... add seems to use registers where as div provided the value to be divided (?)

Mark Hi

Hi guy's

Pls I have a question

read the rules first

Pls where are them

@dima Hy

Any programmer here working on a project?

why its output is 1 2 3

That means the local auto variable "sum" uses the same stack location for every each loop. The initial value of "sum" can be any random number in a normal system.

Or the sum is compiled as a register (after optimization, most likely)

why its output is 1 2 3

Undefined behavior, could be whatever, please compile with warnings enabled

This depends on the architecture, anyway you usually provide the register you divide by not the one to be divided Also when it comes to constants, you can move them to registers while you have them

That was a wild guess, hence the initial (?) because you specified the dividend

I am having some errors in my C code... In graphics.h, I first initialized the graphics and then tried this function: initwindow(100, 100, "Hello World"); But this gave an error of graphics.h dont have a function initwindow?

Do not use graphics.h

Then how do I make graphics??

Any other library??

Any other library??

OpenGL (SDL), Vulkan, etc

Note that SDL is based off of OpenGL, and tailored towards 2D game development.

ncurses

ncurses

ncurses is for terminal gfx

SDL or SFML is a lot more robust in that regard

You just have to install a plugin for C support

class, abstract class, interface, enum… what is some kind of „term“ that groups all these words? I’ve got it on my tongue but can’t hella remember, i need it to name my variable properly 😄

Maybe data structure

naaaah

it’s not object, blueprint, datastructure…i have different word in the back of my mind

There's no interfaces in C++

not a C++ question xd sry for that

Look how this concepts defined in standard draft

Read about what macros are in the internet

So?

Macros are not callable

They are not called that way

I call them "shit code"

Read C++ core guidelines' section about macros

cause in the place Macro is called we get simple substitution Macro body(instead of actual call like function)

Read C++ core guidelines' section about macros

Oh there's no section about macros

I don't think that read outdated literature is good for you education

Using macros to write inline function considered bad practice even in C since C11

I'm pretty sure it always was a bad practice :P

Inline substitution they mean maybe?

Not like vars ofcourse

Just to clear my doubt, Then inline functions are also not good?

They are good
