someone know what is mbedtls

do you know what is it for

Mbed TLS is a C library that implements cryptographic primitives, X.509 certificate manipulation and the SSL/TLS and DTLS protocols.

what does it mean

is it like to encrypt things

From what I just read now, it seems like it is telling the compiler to use either MINGW printf output system or Microsoft printf system... But I could be wrong.

You will be able to debug/print stuff into the terminal of visual studio code as long as you execute the program from there

But why ?

Python project development != c++ project development

Python project development != c++ project development

in the c++ project development workflow, what's the best way keep watching variables values and functions outputs while programm is running?

!res

#include<iostream> using namespace std; class animal { private: int leg, wings, horn; public: string species, blood; void setData(int l, int w,int h); void getData(){ cout<<"The name of the species is "<<species<<endl; cout<<"The temparature of it's blood is "<<blood<<endl; cout<<"It has "<<leg<< " legs "<<endl; cout<<"It has "<<wings<< " wings"<<endl; cout<<"It has "<<horn<<" horns"<<endl; } }; void animal:: setData(int l, int w, int h){ l=leg; w=wings; h=horn; } int main(){ animal cow; cow.setData(4, 0, 2); cow.species="Mammalia"; cow.blood="cold"; cow.getData(); return 0; }

https://onlinegdb.com/lCSbYaVh_ Good afternoon, I will be very grateful if someone can explain to me why my dobutok function is not working correctly. Really very urgently needed

I don't understand why this not movenext

Hi, how do i get the line that starts with a * in regex

Hi, what is the Problem of while (cin >> num) { … } terminate by input

\*.* ?

https://godbolt.org/z/KGofeTzns why I can't implement like this?

This stems from your misunderstanding of inheritance. A derived class has access to the base class parts of it's base class subobject. This does not mean it can access the protected parts of any A object. For example assume there is a base class A with a protected member 'data'. If there are two publically derived classes B and C, then members of B can access only the protected members of A within its subobject. They can't cast a C object to an A object reference and then access 'data' member within it. That would be forbidden by the compiler. This is precisely what is happening in your code as well. You are trying to get a member function pointer to a member function in DerivedT. Though accessor derives from DerivedT, this does not access the DerivedT subobject within accessor. This is a independent access and is hence flagged as an error by the compiler.

so the example code of this wikipedia(CN site) is wrong= =https://zh.wikipedia.org/wiki/%E5%A5%87%E5%BC%82%E9%80%92%E5%BD%92%E6%A8%A1%E6%9D%BF%E6%A8%A1%E5%BC%8F

If you want to match an entire line beginning with atleast one asterisk, you should use the regex "^\*+.*$"

"[*]([^\n]+)&" this did the trick 👍

regex?

msvc v19, it works fine

msvc v19, it works fine

Msvc is a decent compiler in that it supports more standard library features and core language features than GCC and Clang. But they are also known to allow extra features that are prohibited by the standard. Both GCC and Clang do so as well but they give you the options to treat them as extensions which you can enable or disable. For ex in C++17, you can't capture a structured binding variable in a lambda by value. You have to use init capture to capture such a variable. But MSVC allows you to do so and doesn't flag it as an error. Clang doesn't. GCC allows it as an extension which can be turned off if you want strict standard compliance.

In the answer of the exercise, it is written: if (size == 0) return ((char *)malloc(sizeof(char))); what if we return (0)

you cannot call free(0); because that is invalid pointer (and it haven't even been allocated with malloc)

Nope, C standard explicitly says that calling free with NULL is fine and does nothing

In case of capturing structured bindings I'm on the GCC side or at least MSVC, afaik it was basically a bug in the standard

Doesn't matter what you or I desire. Standard is the last word and strict compliance with it is necessary. You can extend the standard as long as you give people a way to disable those extensions. MSVC didn't do this which is wrong. It has been fixed in C++20.

Well, yes but there's also common sense, if you make something that is by the paper but that will only add more suffering to everyone.. will it be better?

Is that better than avoiding portability? What if one compiler supports it and another doesn't? Where is the common sense in supporting non portable code?
