Is this wrong?

yes

char ab = "a"

Haven't you got any warning from compiler?

I didn't understand the error, it said something about assigning constant to variable

yes "str.." returns a pointer to const char and 'A' returns ascii code of that letter which is just plain number

You will then have to use the OS read and write calls instead of using C std library. And you also have to program your terminal emulator or the pseudo terminal to interpret Ctrl+D in a different way. I don't think a project for a student just learning about shells would be this involved. Check with your teacher on what he/she expects

I'll try that We're learning C, writing the simple shell as a way to see how the stuff we've been learning comes together.

In that case, the professor shouldnt expect you to handle EOF for input and stuff. At best you should be able to spawn new processes for commands entered and also handle pipelining of commands. That should be a good enough exercise. I would avoid pipelining as well for beginners because that involves system calls to dup, dup2 et al

hi, I'm having some troubles with meson! I have this: project('tgbot', 'c', version: '0.1.0', default_options: ['warning_level=everything', 'buildtype=release', 'strip=true', 'debug=false', 'optimization=3']) but I don't know why doing file exec gives: tgbot: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, with debug_info, not stripped why it has debug_info and it isn't stripped?

It will be stripped during install

Can i ask you for electronic engineer which programming languange should i learn

Most chip development is done with C++/ SystemC C++ class library where bit accurate models of the chip/subsystem are developed to iterate quickly on architecture exploration of chips and sub blocks. You can have a loosely time C++ model which shows what the output behavior of the system will be, there are also clock cycle accurate C++ models too.

../src/message.c:27:9: note: 'snprintf' output between 1 and 1024 bytes into a destination of size 512 27 | snprintf(man_res, MAN_SIZE, "%s", line); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ why it says this? is this the right way to use snprintf? MAN_SIZE is 512, line is 1024chars and man_res is 512chars

Warning message looks quite clear. What don’t you understand?

because I wrote that he needs to write MAN_SIZE to man_res from line...

Nope, it says that buffer line of 1024 bytes long is written to smaller buffer man_res of 512 bytes

and that's what I want, I mean, it has to truncate the 1024 buffer to 512 buffer

sprintf as it’s written in your code won’t truncate anything

If you really want to truncate line buffer, you may want to specify length in %s(like %.511s) or use some other way

in php we can use madelineproto to make clients apps what can we use in c++

#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit cannot open source file "filesystem". Please run the 'Select IntelliSense Configuration...' command to locate your system headers What's the error

On running the code it shows fatal directory I downloaded the mingw w recently but it shows GCC version 6.3.0

what is wrong in my code

And just for the sake of clarity, would probably be better to make a "is_prime" function that would return a boolean value which you could use into this if statement

are there any groups for Java in english and/ or Russian?

Guys, if the sort algorithm sorts values ​​in ascending order, does there have an algorithm that sorts in descending order?

Guys, if the sort algorithm sorts values ​​in ascending order, does there have an algorithm that sorts in descending order?

It is the same algorithm but with other comparator

Yes, it depends on how you define comparison

What's this paragraph means? "You should have something like /build* in your .gitignore , so that users can make build directories in the source directory and use those to build. A few packages prohibit this, but it's much better than doing a true out-of-source build and having to type something different for each package you build."

Is that's correct meaning of out-of-source build?

Can you recommended me any free comprehensive c++ learning resources?

Dunno about comprehensive.. But try learncpp.com

Could anyone explain "Function Overloading" in simplest terms please ?

#include <stdio.h> void main() { int age[100][10] = {0}; int person; char name[28][10] = {0}, email[28] = {0}; printf("Enter the number of travellers\n"); scanf("%d", &person); for (int i = 0; i < person; i++) { printf("Enter the name of person %d\n", (i + 1)); scanf("%s", &name[i]); printf("Enter the age of person %d \n", (i + 1)); scanf("%d", &age[i]); } for (int j = 0; j < person; j++) { printf(" the name of person %d is %s \n", (j + 1), name[j]); printf(" the age of person %d is %d \n", (j + 1), age[j]); } }

@ItachiUchiha420 Errm is there a question?

can you please check what happened before this message? If I know which event caused that I can fix it

C++ full notes

Nopes the message was not for the bot or for you but for the person who posted the code. The point is that the person posted a chunk of code without any related question.

I don't understand why it is quoted a message posted in 2022, thats why I'm asking

how to check what line of my c code has a segfault

is there any way to do that from terminal

a=5 B=++a + a++....? Why does the value of b come to be 13 not 12 in the above expression?

This is undefined behavior. There is no right answer. See Undefined behavior
