In fact, IDE is not necessary. Someone use vim or emacs also coding.

If you use windows os. maybe the WSL is a good choose.

Can anyone help me through, I am new to c++ and I have been trying to download a ide , visual studio, but I can only see 2022 version is only .net related

winlibs.com for gcc and g++ vscode as code editor

I use macOS

winlibs.com for gcc and g++ vscode as code editor

I guess I should stick with vscode

Thanks 👍

I guess I should stick with vscode

macos is ok, homebrew install gcc / clang. And because the visual studio in mac is not better than windows.

compile it in your terminator.

I guess I should stick with vscode

visual studio is for windows only

visual studio code (VScode) is cross-platform but it’s a text editor so it doesn’t compile your programs for you, you need to install a compiler on your system

yes but you still need a compiler for the extension to work there is one called clang that I think will work the best for you

I have that installed ..

Working for me

ok then compile your programs with: clang file1.cpp file2.cpp file3.cpp then to run them: ./a.out

I have that installed ..

write this ☝️ in your terminal then press enter

#include <stdio.h> #include<stdlib.h> int main() { int *a[10]; a[3][2]=5; printf("Hello World"); } how a[3][2] is possible ? not giving any error also printing hello world

no its int *a[10]; in c lang

onlinegdb

at compile time ?

I have an assignment for c can anyone please help

What happened that you haven't finished it before? What are you struggling with?

I was absent in class due to illness.

And I am very weak in c programming

#include <stdio.h> #include<stdlib.h> int main() { int *a[10]; a[3][2]=5; printf("Hello World"); } how a[3][2] is possible ? not giving any error also printing hello world

the in* a[10] means a pointer nums, every elemens in nums is a int*, and here you define a in* a[10] in stack memory place. you don't init it. but you assign a[3][2] , a[3][2] means the nums of second pointer and offset two sizeof(int) address,

you assign a no init memory is a undefined behavior in C / C++ progma.

No

hey guys , i am new c++ programming can anyone helps me with a free website or a youtube channel .

someone know what is the difference between open() and syscall( open number )

I have a problem I gotta send a picture to show it can anyone help ?

someone know what is the difference between open() and syscall( open number )

i mean the open in fcntl.h

Protocol Decoding program in c/c++?

radare2 is a really good option ghidta is more popular and considered more professional ida is expensive and less powerful (but it has easier to use gui tbh) there is a one called plasma thay generates pseudo-code and it is easier than the previous three

all require some knowladge in assembly

note that ghidra decompilation is known to be better

well ida is okay but eventually you will end up learning to work on more than one framework each one has it’s pros and cons if you started with ida then don’t switch to any other framework unless you become more proficient with it

hello, looking for low level C enthusiastic to chat with. interests embedded, micro systems, all unix and system V flavors or unix and linux. currently ive found a curiosity statically linked executable and the shrinkage of them. wondering if anyone has had much experience with tools or strategies of shrinking a code base even further than the normal optimizations and stripping (gcc arguments and strip arguments)

love looking at old school programming projects where they were hardware constrained such as sub 100kb game ROMs and early computer programs, so much code, so little space/size

#include <stdio.h> #define print(x) printf("%d ",x) int main() { int z=10; print(z); int x=5; print(x); }

i think it should give error because of print(z) but it is not giving its so my question is how print(z) is replaced by printf("%d",z); when i have define print(x) printf("%d",x);

how x is replaced by z

thats just the macro variable name

when you pass a variable type or pointer to a function or processor macro, the name you use it as in the function/macro does not matter

as long as its of the correct type, and if multiple arguments as long as the order of the types are in correct order it should not matter what they are called

the program isnt seeing you pass the human friendly letter X, its seeing a computer address, that name you see is just in the programming language to help the human understand notice how the value is the same? regardless of what var name you use? try the same, but pass a pointer and print the pointers address, maybe that will help you understand

Hi, I am a newbie to c++ and I am not able to move ahead from functions and structures that are irritating me a lot how can I deal with it and know it better?

Why are you not able to move ahead, is it something specific that you need to understand but have trouble with, or something else?

First, have more hands on the language with basics like arithmetic operations, loops, if/else, then go on structure and pointers. It'll take time initially.

I can’t understand questions related to structures or udf

I am fine with arithmetics and loops but structures and pointers etc are being complicated for me

Yeah that's difficult, practice more on it.

Just look on online resources, books or you can try on hackerearth, codechef.

this two are binary conversion program... but both work differently i dont know why?

one converts successfully (bcz i copy pasted it from tutorial )..but one dosent (which is made by me 😭)

Look at == and =

same it is.. im i missing something?

same it is.. im i missing something?

No, = and == are not the same. One is an assignment, the other is a comparison, respectively

#include<iostream> #include<string> using namespace std; int main(){ string s; cout<<"enter any binary num"<<endl; cin>>s; for (int i = 0; i< s.length();i++ ){ if (s.at(i) == '0' ){ (is it this line?) s.at(i) = '1'; } else{ s.at(i) == '0'; } cout<<s.at(i); } }

thanks..... now i get it

How do you link dynamically to a shared library with conan+cmake? I've tried anything but the docs were unhelpful.

Thank you

Sorry, i would ask if code ofuscation work for protect source from reverse engineering (assembly), like read strings or functions
