I want that how to make an enemy chase the human player who is moving with keyboard in c++ on console
I think this question requires more information.
What engine you use, do you want to calculate a difference that enemy should move each step when going directly towards a player or you want to write pathfinding that avoids obstacles, or game AI that switches between states?
Also this chat may be not the best fit since it doesn't look like problem related to C++ (rather generic problem), you may try to check a game dev chat in telegram, e.g. from these guys: http://thedevs.network/

Let’s just say that making up with this problems is your work as a developer
But
This is a common situation and probably someone else got a solution already
Check google at first, stack overflow, ecc…

hello guys i want to know how to do this: im new on this but i got an assignment were i have to make a program on the master (master) side with the primitives for
communication in PVM and also have the command line as capture. all with linux and the program must be carried out on the slave side (slave) with the primitives of PVM, receiving the parameters, i have the code but i dont know how to run it on linux

sorry for my bad english, its not my native language

Line 24, pass the DP vector by reference, you're passing it by value. It's getting copied everytime the recursive function is called. The could result in a memory limit exceed and/or time limit exceed.

Sometimes I notice that C++ project has .cpp and .c files (also for headers .h and .hpp) What the reason to create different format files?

c files comes from c language. The compiler expects those files will be compiled as c, not as c++; the .hpp or h format extensions for headers are not relevant for the creation of applications nor libraries.
Jose
Compilers like gcc threat cpp files as C++, c files as C. Take care of it 😁

Hi guys, I have a problem with ncurses libraries.
So I must spawn a new terminal window in a signal Handler, and I was told that the ncurses functions are able to do that.
Shame that they are blocking and generally non safe to use in signal handlers.
So I looked up on the internet and found that the library PDCurses was made to be thread-safe. Is it true?

Technically speaking, no io is signal safe

there is no way to make it safe in a signal handler? I made wgetch safe by using nodelay(), but I don't know how to make other things safe

Is it a good idea to devide a numer by two using bit shifts

You can try to use signalfd instead of the traditional signal handler

no, compiler will do it automatically(where appropriate), please optimize for readability

What left and right shift operater do??

What left and right shift operater do??
>> And << do???
they shift bits,
111 << 1 => 1110
111 >> 1 => 11
Buffer
What left and right shift operater do??
>> And << do???
These operators basically shifts the binary bits to left/right accordingly.
For eg. 5>>1 will give 2. This is bcz 101 is binary equivalent of 5 and upon shifting 1 bit to right of (101) it will become (10) which is nothing but 2.
In general , lets say 8>>n = 8/(2^n) means upon shifting right by any number is equal to dividing that no. By 2^n.
And left shifting means multiplying by 2^n.

This for cout ←← it print sentences or whatever on the screen

Does any know how to get modules to work in vscode for MSVC? As in, import <iostream>?

I have the following flags set;

/experimental:module

/scanDependencies
/internalPartition

But I keep getting the error message that import is not a template

i get an error

undefined reference to `File::OpenFile(char*)'

but i have defined it in the header file and it is overriding a super class virtual method

class File {

int OpenFile(const char *fname);
virtual void ProcessFile();
};
/
#include "File.hpp"
class STFile : public File {
public:
void ProcessFile() override;

why it says undefined reference
/
/
this is also the implementation: #include "File.hpp"
#include <fstream>
int File::OpenFile(const char *fname) {
file.open(fname, std::ios::binary);
if (file.is_open()) {
return -1;
}
return 0;

#include "STFile.hpp"
#include <fstream>
void STFile::ProcessFile() {

#include "STFile.hpp"
#include <fstream>

Use pastebin or godbolt

what is your problem? Issue description.
iostream is old library and you don't need latest std version of whatever

/std:c++latest
/experimental:module
/ifcSearchDir
/scanDependencies
/internalPartition
I don't use Visual Studio, but did you check if on the version you are using, std:c++latest refers to C++20. It is possible that you are using an older version of Visual Studio.
Moreover from what I read in the past Microsoft did not support module header units for a long while. They instead went the way of creating a separate module named std and partitioned it into partition units like compat and so on. So Microsoft required users to use something like import std.core; or import std.compat and so on. The support for header units came a little later. It is possible that the version you are using didn't have this support. I am not sure though.
Other compilers like GCC and Clang went in the other direction. They started supporting modules the easy way i.e. using header units and global module fragments but are yet to support "standard library as a modules feature". This is why Microsoft is well into C++23 support while GCC and Clang are still lagging behind with their C++20 implementation itself.

#include "File.hpp"
class STFile : public File {
public:
void ProcessFile() override;
};
. <- Have you included this file in the list of files to be compiled by compiler
A common mistake most beginners make with C/C++ compilation is that they assume that when a CPP file includes a header file say a.h then the corresponding implementation file i.e. a.cpp is automatically compiled. This is not the case.
If you have multiple CPP files, you have to specifically request the compiler to compile all of them

It has support through visual studio but it doesn't seem to work in visual studio code. I installed visual studio community edition 2022 and can compile module headers in my code through the import statement in visual studio. But I'm unable to do so through vscode

because VS using msbuild and it do magic for that, in VSC you need something ( cmake, ex) for that
cmake supports modules since 3.25
