The keys don't have any relation. It is just that both the keys have same value. Now, copying a new vector is expensive so I want the value(here vector) to be transferred.
If you don't care for previous values consider using swap on values

swap(mp["hi"], mp["hello"])?

So, the vectors get swapped. Oh!! Why didn't that come into my mind?
Igor🇺🇦
Yes. https://en.cppreference.com/w/cpp/container/vector/swap2

I have an class iterator inside my class.
My class have a struct inside, used to store data. class iteretor should be able to override std::cout to print the struct inside my class
professor
how can I force to my own program giving more stack `_declspec(noinline) int old_main(int argc, const char* argv[]) {
` using the args from old main?

Did i missed something? @K11M1 looks like you purged something

Declare operator<< with iterator as second argument

This isnt possible in runtime, only via compiler flags
Artöm
Wym how
Artöm
Yes

Not a question, just wanted to show off. I just got max grade at my C++ exam (program engineer student in university)

Well done

#include <stdio.h>

char s[100];
scanf ("%s",&s);
if (strlen(s)%2!=0) {

what does this code answer?
s[strlen(s)-1]='\0';
Anonymous

s[strlen(s)-1]='\0';
It deletes last symbol of string basically
Сарвар
Thank you!!

Just want to point out that you shouldn't use strlen all the time. It goes over the string every time. Just store it in a variable. The length doesn't change here

hi guys
Dero
i'm here 'cause i really need help on a project i'm doing now, i'm stucked on a function that may be a recursive way to create an AST of a parentesis in a algebraic symbolical parser but in practice the parentesis are not correctly linked with the function_linker and if the parentesis is something like
(( x + y ) * b )
It just get stucked

Is there a way to encode strings in C ++ And protect it from hex editor ??

Just Use obfuscate

I didn't try this method but people say it works https://www.codeproject.com/Articles/502283/Strings-Obfuscation-System

Plenty. But its impossible to protect it from hex editor, that is, its possible to decrypt it back

Not really, it just takes null term one char back and it's damn bad code to use. Strlen changes every time, you should hold length in a seperate variable.

There are lots of ways...

There is no way to protect a string in a program without depending on user input. Why do you want this?
Pavel
I would say, there's no way to fully protect it, but you still can XOR it to make extracting the values more difficult
Asdew
With or without user input?
Pavel
without, I mean just encode it with a key stored in the app itself
it's still easy to crack, but at least some newbie hackers won't be able to do so
klimi
okay sorry... how is this related to c++?

Hi everyone. Is it smart to say that cloud computing has brought C / C ++ back to servers that house high-performance applications?
Now that processing is charged per second, I think the more efficient the better and the cheaper to maintain. Except if companies are really willing to have servers full of script running millions of cycles toasting billions like a bitcoin from hell.

take nginx for example
