python is like writing english

Are you new to programming?

don't we all? i still use it though

me too

don't we all? i still use it though

😂

i feel ur pain

Well, every language has its own characteristics and goals

soooo many things to keep in mind

but i feel that from learning C++ i actually got the sense of programming

like more understanding of computers and what we are exactly doing

We have high-level, low-level and intermediate languages The higher the level, the easier it is for humans to understand

😂😂 u will too

no, python is higher than C++

c and c++ is more machine friendly

Go research programming languages I think this is a good start for this path

its better to learn, but are u going to use it ? most probably no

Learning Python may be enough to hack around a small web server or a tiny prototype, but it will neither teach you as much (in terms of computer science knowledge) to learn Python instead of C++ C++ encompasses a lot of tools for manipulating the computer the way it actually operates as well as advanced concepts like dependent types, constraint based programming, generic programming, static and dynamic polymorphism, resource management, functional programming and lambda calculus

@QNeko Yes sir I'm using GCC compiler in Linux. I heard that while debugging with GDB we can see the memory where it is located. But I need to see where the memory allocation by the CPU either in register or stack at run time

The choice here is not the CPU's but the compiler's. You can learn that by reading the generated assembly by compiling with the -S flag on GCC or Clang

I didn't like C++ STL

You can try layout asm to disassemble the binary

I didn't like C++ STL

what you want to compare with this

why not stl

What's wrong with this Char c = 'w'

What's wrong with this Char c = 'w'

char instead of Char, missing semicolon at the end.

cout<<"hello everyone";

How do I print the names in enum instead of their values? enum status( true = 1, false = 0) cout « status(1); output: false. (not 0)

How do I print the names in enum instead of their values? enum status( true = 1, false = 0) cout « status(1); output: false. (not 0)

When a C/C++ program compiled the information about enum value names is not saved with the program. So you need to code the conversion yourself (e.g. store an array or map of names by their values)

Can I run code written for an visual studio IDE editor in another editor?

How can I check if the data type is integer? unistd.h library only allowed

Can I run code written for an visual studio IDE editor in another editor?

ofcourse!

Hi all! Could it be that I haven’t strndup function, while I have strdup in my compiler? #include <string.h> char* strdup (const char* str); //available char* strndup (const char* str, size_t n); //I haven’t got this one

But I can just do this: char* strndup( const char* str, size_t size ){ char* res = strdup( str ); if ( strlen(res) > size){ res = realloc(res, size); res[size-1] = ‘\0’; } return res; } But it is boring, you know?

That's literally what C programmer does when they need something non existent. They implement it themselves

Hey guys What do you use to debug your c++ code Like in visual studio code It's get confusing sometimes Do you guys any simple(visually easy looking) way to do it ..... Or just reply this message with what you use as an ide

Hi, visual studio (and some other IDEs) has an integrated tool called "debugger", it allows to execute your application step-by-step and investigate the state of the program on each step. I usually put a "breakpoint" in the code that I'm interested in and execute the program until the breakpoint is "hit", then go step-by-step and look at the state (basically what values the variables hold).

hello! I have a quick question. What does a program do when I run it using “./main &”?

is it run sequentially or parallel?

thank you!

I have problem when use include<freeimage.h>and the stackflow it is not have solution for my problem

<freeimage>not found

But I can just do this: char* strndup( const char* str, size_t size ){ char* res = strdup( str ); if ( strlen(res) > size){ res = realloc(res, size); res[size-1] = ‘\0’; } return res; } But it is boring, you know?

Maybe you enable pedantic or using standard. strndup is defined on POSIX.1-2008

How can I check if the data type is integer? unistd.h library only allowed

Just check the sizeof the data, library doesn't have any related to data type. int in x86-64 arch on linux is 4 byte so it is double word Note : I haven't explore more about assembly Use equ to find its size section .data arr dd 0 ; static int arr = 0 str db "sizeof int is " ; static char str[] = "sizeof int is " len equ $-str ; static size_t len = sizeof(len) sz equ $-arr ; static size_t sz = sizeof(arr) section .text global _start _start: mov edi, 1 mov esi, str mov edx, len mov eax, 1 syscall ; write(1, str, len) mov eax, [sz] add eax, 48 mov sz, eax mov edi, 1 mov esi, sz mov edx, 1 mov eax, 1 syscall ; write(1, sz, 1) xor edi, edi mov eax, 60 syscall ; _exit(0)

You need to add the include path in compiler. Don't forget to add the lib file in linker

You need to add the include path in compiler. Don't forget to add the lib file in linker

I added it in the build settings but it didn't work

Check added path is accessible from your project folder

#include<stdio.h> #define n 5 int main() { int a[n],b[n],i,j; printf("Enter the FIVE elements of array : "); for(i=0;i<n;i++) { scanf("%d",&a[i]); } printf("original elements of array : "); for(i=0;i<n;i++) { printf("%d ",a[i]); } printf("\n\n\n New arry with reverse element : "); for(i=n-1,j=0;i>=0;i--,j++) { b[j]=a[i]; } for(i=0;i<n;i++) { printf("%d ",b[i]); } return 0; }

How can I do it with single array

You swap a[i] with a[len - i] and vice-versa

Is someone familiar with the "Effective STL" book ?

what are header files like a simple explanation? what i understand is they are files that have stocked functions or serve a functionality in the code like imports in oop ?? i guess i don't understand it if c was imperative then why and how and external ( header file that's not inside the code ) get's called inside the code and do it's thing i don't understand

header files allow you to separate your project in segments

you have a header file with declarations, and a cpp file with definitions

if you change the cpp file, only that gets compiled, and everything else remains the same

if you put the definition in the header file, everything that uses it must be compiled again for every time you change it

so, it's easier and more efficient to keep your definitions in a file apart to avoid extra compilation time

you have a header file with declarations, and a cpp file with definitions

What about in the c language like they're using header files as well

What about in the c language like they're using header files as well

yeah, sorry

i default to "cpp" because im used to it lol

You were talking about or cpp

but both C and C++ header files serve the same purpose

Ohh okay cool

Hi, I have a problem using std::execution, Clion throws the following error: fatal error: tbb/blocked_range.h: No such file or directory 19 | #include <tbb/blocked_range.h> | ^~~~~~~~~~~~~~~~~~~~~ I tried to solve this problem by adding this line to the CMakeList target_link_libraries(test PUBLIC tbb) But nothing helped
