How did you get that encrypted string?

How did you get that encrypted string?

What is happening in code below? enum Color : int { RED }; Color foo() {...} I've never seen enum type in function name.

Function foo returning enum value

Instance of enum?

it is from a program

Well, then I would check if you: - have correct input string - have correct key - using correct algorithm (e.g. maybe you were supposed to skip the plus)

Yes

What could be the possible reasons why the normal int function is not used instead? And that instance will have value 0

Access Violation C0000005 your string literal is read only and can't be changed. // string literal that can't be changed char * s1 = "Hello"; // modifiable string char s2[] = "Hello";

But i know it should be const to not be changed

qmemcpy(v17, "+Hogqi&fjbj![xcwrp1Cy{xo|ti[gCDRWMJHoIGNldp8-S", sizeof(v17)); while ( v12 != 46 ) { sub_AA90(v12 + 46, v11); v17[v12++] ^= v13; }

Hi ✋ I have a solution for my answer, but this way I assume is worst practice :) is there any way that I can create a class with variable size ? And enable or disable member variable of class ? Like in this code : https://godbolt.org/z/csqdebc8s

But i know it should be const to not be changed

#include <stdio.h> #include <math.h> double add(double x,double y){ return x+y; } int main(){ double x , y, result; printf("Enter two numbers : "); scanf("%lf %lf",x ,y); result = add(x, y); printf("%lf",result); return 0; }

checked, not having issue with it

#include <stdio.h> #include <math.h> double add(double x,double y){ return x+y; } int main(){ double x , y, result; printf("Enter two numbers : "); scanf("%lf %lf",x ,y); result = add(x, y); printf("%lf",result); return 0; }

Server::Server( char letterName) : name(letterName) { /*Intentionally empty*/} is there anyone who knows anything about ": name(letterName)"? the relevant class is like the following class Server { public: Server( char letterName); static int getTurn( ); void serveOne( ); static bool stillOpen( ); private: static int turn; static int lastServed; static bool nowOpen; char name; };

Scanf function waits the address of variables but you didn't pass. you should use &x , &y that gives the address of variables to scanf function. You should change scanf("%lf %lf" , x , y); with scanf("%lf %lf" , &x , &y)

Hello, I am desiring to load 2 files into std::string. I am currently using one std::ifstream and one std::stringstream but to clear the stringstream i am using stream.str( std::string() ); stream.clear(); but since i am resetting it, that means i can move the std::string and that should clean the str so i wouldn't have to do the stream.str(std::string()); line. But when i actually try doing source1 = std::move(stream).str(); Then i see the content in the stream in the second str call anyway, am I overlooking something? thanks

Calling move doesn't guarantee that actual move will happen, it just transforms the reference type, so imagine your code as something like static_cast<stream_type&&>(stream).str(); So if str.() doesn't have overload for rvalue ref, which is rarely a case for a member function, then it will just call the function as if there were no std::move invoked

Well but at least this should get called no? std::basic_string<CharT,Traits,Allocator> str() &&; 3) Returns a string move-constructed from the underlying string. Equivalent to return std::move(*rdbuf()).str();.

ah ok, so there is an overload

i hope, i am trying to compile it with cmake so i use set(CXX_STANDARD 20)

try set(CMAKE_CXX_STANDARD 20)

just this does the trick... damn i feel stupid :D

The one you used is set up per target https://cmake.org/cmake/help/latest/prop_tgt/CXX_STANDARD.html#prop_tgt:CXX_STANDARD

just want to ask that , if its ok for a beginner in coding ( c lang) to join this grp , i read about this grp somewhere on net so is it ok if i ask some silly questions related to c lang?

I'm trying to connect my database with my c++ code and while im installing the necessary files, it requirs me to install the "libmysql.a" file, but i couldn't find it anywhere online. Is it the same as "libmysql.dll"?

strcpy also should works

I guess the easiest way would be char string[] = "hello";

but if you were trying to communicate between a two programs written with two programming languages ,then using interprocess communication or udp sockets in address 127.0.0.1 is better
