const char* const ptr[3] is double pointer. You should have written const char* const* const ptr = ... (I am not sure, though).

its was in exam in my university

int main (){ const char* const ptr[3]= {"Ariel","University","BANGKOK"}; char *s ="hey"; (&s)[3] = "a"; ptr[2] = "b"; for (int i = 0; i < 3; i++) { printf("%s\n",*(ptr + i)); } return 0; }

There are other bugs, as well

i think that i could

int main (){ const char* const ptr[3]= {"Ariel","University","BANGKOK"}; char *s ="hey"; (&s)[3] = "a"; ptr[2] = "b"; for (int i = 0; i < 3; i++) { printf("%s\n",*(ptr + i)); } return 0; }

This won't compile

how can i make GUI tools in C

You reassign constant

Hi guys

Is anyone here have experience in using Whitesource bolt ?

Is there a library that makes working with databases easier?

like django orm

Is there a library that makes working with databases easier?

Databases usually have c/c++ wrappers

Function signatures? What exactly you don't understand about them? (it's a big topic to explain it all)

hi

Someone is a strong C++ here?

I need some help

Where can I use strlen()

Yeah like you are not wasting your time by typing this😂😂😂

How backwards your reasoning is..😂

Since you're not very bright here is some explainer : https://letmegooglethat.com/?q=strlen No need to thank me.

Please get a job... I know this is not the actual search... Why do you waste so much time instead answering the guy...😕... You have a problem in your coconut

What does strlen() function mean

You ought to have read some manpages... From man strlen: "strlen - calculate the length of a string" #include <string.h> size_t strlen(const char *s); "The strlen() function calculates the length of the string pointed to by s, excluding the terminating null byte ('\0')."

Why would you answer somebody who didn't put the effort to just google the stuff to begin with? It's literally just second away

Thank you very much.. Finally someone who has common sense. 👍

You are part of a growing problem I think we need to address . You are part of a group of people who speak absolute trash without having any actual knowledge. This is a group created to help others , you must not be impolite because someone's question is stupid or can be found on google. If I were the admin I would have banned you already. Please change.

You didn't have to be a little girl because nobody had answered your "serious" question. Get over your narcissism

Wasn't the one who asked the question just concerned someone would be so impolite because of someone asking something.

I think the way there is a "Python" a "Python Talk" (gated entry after passing a little test) and a "Python Offtopic" group is probably a model the admins here should consider.

Lets people looking for different kinds of chat environment find them and get along nicely. Just a thought.

#include <iostream> #include <filesystem> using namespace std; int main() { filesystem::path folderpath = "InternalStorage:\\c++\\"; if (filesystem::exists(folderpath)) { cout << "The path: " << folderpath << " exists."; } else { cout << "The path: " << folderpath << " does not exist."; } }

<stdin>:2:10: fatal error: 'filesystem' file not found #include <filesystem> ^~~~~~~~~~~~ 1 error generated.

<stdin>:2:10: fatal error: 'filesystem' file not found #include <filesystem> ^~~~~~~~~~~~ 1 error generated.

Why this is the compiler output to the above code?

<stdin>:2:10: fatal error: 'filesystem' file not found #include <filesystem> ^~~~~~~~~~~~ 1 error generated.

Filesystem is in experimental in some versions of compilers, you may want to include #include <experimental/filesystem> Or update your compiler https://stackoverflow.com/questions/39231363/fatal-error-filesystem-no-such-file-or-directory/39231488

Ok. Thank you 😊

The question was what do you use cout or std::cout. I prefer using fmt::print it has much nicer syntax and is faster

OK how do you get Fmt::print Do you have to inculde a preprocessor directive Because Std::cout is in iostream.h

Yes you are right Maybe One on one explaination is his best method of learning How do you see that ?.. Just saying 👍

https://fmt.dev/latest/index.html

Thanks #include <fmt/core.h> 👌😌

That would only work after these steps. https://fmt.dev/latest/usage.html It's not C++ standard.

it's in <iostream>, not <iostream.h>

I wish someone would implement std::format already

Ok

Dima was faster :(

Hey, I have a question for yous. I have limited experience of programming in general. Just little scripts here and there to solve problems. I am good with basics of c++ and now I want to dive deeper. I believe a good practice would be to start studying some open source app and learn how they coded it to get a sense of it. My problem is, I don't even know how to read some open source app. It's just so much of code (even small projects) for me to get started with. Do you have any tips on how do you READ someone's code to understand how they developed that app. For example, let's say implementation of "ls" command on Linux.

i have a que difference between array and pointer

i have a que difference between array and pointer

Totally different

how

im not talking about that little difference of sizeof() and else

how

In any way

im not talking about that little difference of sizeof() and else

It's not little

int a[]; int *p=a; std::cout«a«std::endl;

int a[]; int *p=a; std::cout«a«std::endl;

So?

std::cout«p«std::endl;

whts the difference

Array decays to pointer
