even if it is not a valid C program it is still a C program, but… Invalid lol
Not valid C program => not a C program

A broken keyboard is still a keyboard even though it does not work
It doesn't work that way

to me everything that compiles with a c compiler is a c program

A program that doesn't satisfy ISO C is not a C program

Any one plz explain this question

Any one plz explain this question
Um so this "question". Is actually not a real question. It looks more like a task or homework.

Hello people,
i want to reduce cyclomatic complexity of switch case code , using lambdas.
Any suggestions on how i can do this?
A
can we replace switch case code with lambda functions?
Vlad
So basically you'll have switch case inside the lambda)

hey, i get string object from function
MRT
std::string sx = ....
std::cout << sx.length()// its 84
const char *x = sx.c_str();
std::cout << strlen(x) << //its 4
std:string x2 = x;
std::cout << x2.length() << //its 4
why ?

Tho it's kinda off topic
You can learn Dart/flutter for it
If you want to do it with C++(Suggested so to keep up the topic of the group as the rules state so) go for Qt/QML with felgo library, it has a good set of components to deal with different functionalities of both Android & IOS.
You'll need the NDK tools to be able to compile against Android target

If i take dart, i should know C first right?
Enzo
I havent learn any programming language yet
H
I havent learn any programming language yet
doesnt matter -_- just start for one month then start researching whaich language is good for yours ... Just start , don ask 😐
H
at least ask your questions after one month training , it could create good questions :/

std::cout << strlen(x) << //its 4
std:string x2 = x;

why ?
Is original string still alive when you call strlen?
Vlad
I have a suspicion that you call strlen on a dangling pointer

hi guys, i'm a c novice and just began learning c. and i'm a little bit confusing about what should i read next to learn modern c after reading the C Programming Language 2ed (it's a really good book, but i think ansi c might be a little bit old for nowdays XD)

hlo guys

i want to learn c programming.

how can i start

yes, i checked string and find many null object,why in first time gives the correct answer ?
Vlad

Is it in it's scope the first time?
Vlad
const char* dangle;
{
std::string str = "asdf";
dangle = str.c_str();
} // str destructor gets called. Memory is freed
std::cout << dangle; // UB
MRT
You code in C++ bruh
std::string saveRsaPrivateKeyToString(CryptoPP::RSA::PrivateKey &pkey);
std::string sx = saveRsaPrivateKeyToString(pkey);
std::cout << sx.length()// its 84
const char *x = sx.c_str();
std::cout << strlen(x) << //its 5
Vlad
Vlad
Of course key would contain null bytes
Vlad
It isn't a C string
MRT
cryptopp liberaryo documation for save key to string
MRT
i want to send key to client with string
Vlad
It basically loops till the null byte
