Is there another function like getch()?

Is there a function that can perform like getch() without having to #include <conio.h>

Basically I am working on a console game and I am moving the so called sprite character with the arrow keys. I declared an integer key in the global scope and used it within the local scope inside the do while loop assigning it with getch().

Here is a demonstration of the piece of snippet:

#include <Windows.h>
#include <iostream>
#include <conio.h> 
int key;
int main(){
do{
    key = getch();
    switch(key){
        case RIGHT:
        gotoXY(x, y);
        std::cout<<' ';
        x++;
        gotoXY(x, y);
        std::cout<<((char)('\x01'));
        break;
    }
    return 0;
}


I just want to know if it is possible to avoid including another directive that acts like getch thats maybe in <Windows.h> or <iostream>?

Not really understanding those forums. Here is what I tried with an updated version of my partial code I am displaying, while it still compiles with no errors, but no success.

	HANDLE h = GetStdHandle(STD_INPUT_HANDLE);
	DWORD keyPress;
	INPUT_RECORD buffer;
	PeekConsoleInput(h,&buffer,1, &keyPress);

	do{
		ReadConsoleInput(h,&buffer,1, &keyPress);
		//keyPress = _getch(); //Use getch() if compiling error
		if(keyPress == RIGHT){ //Move player right
			sprite->GotoXY(sprite->posX,sprite->posY);
			sprite->posX++;
			sprite->GotoXY(sprite->posX,sprite->posY);
			sprite->Player();
		}


Frustrating...

Including another library is unavoidable for what you want to do. The <conio.h> one is fairly small.

The Windows Console API is a bit less friendly to use for the same ends. It might be worth your time looking at NCurses (*nix) / PDCurses (Windows).

Good luck!

key = std::cin.get ( );

@Yay295

I recently tried that:

keyPress = std::cin.get();

std::cerr<<"But that did not work";

Ok :), looks like I solved the Issue here. Here is my working key input retriever without using the deprecated <conio.h>.

#include <windows.h>
#include <iostream>

int main(){
    DWORD dword;          
    INPUT_RECORD keyPress;         //Input Event
    HANDLE handle = GetStdHandle(STD_INPUT_HANDLE);
	BOOL escape = FALSE;  //Used to escape
    
	GetConsoleMode(handle, &dword);
    SetConsoleMode(handle, 0);

    std::cout<<"Press UP DOWN LEFT (or) RIGHT Key as many times.\n"
		"Press ESC to quit.\n\n";

    while (!escape){
        if (WaitForSingleObject( handle, 0 ) == WAIT_OBJECT_0){
            ReadConsoleInput( handle, &keyPress, 1, &dword );

            /* Only respond to key release events */
            if((keyPress.EventType == KEY_EVENT) 
				&& 
				!keyPress.Event.KeyEvent.bKeyDown){
				switch (keyPress.Event.KeyEvent.wVirtualKeyCode){
                    case VK_UP:
                        std::cout<<"You Pressed: UP Key"<<std::endl;
                        break;
					case VK_DOWN:
						std::cout<<"You Pressed: DOWN Key"<<std::endl;
						break;
					case VK_RIGHT:
						std::cout<<"You Pressed: RIGHT Key"<<std::endl;
						break;
					case VK_LEFT:
						std::cout<<"You Pressed: LEFT Key"<<std::endl;
						break;
					case VK_ESCAPE:
                        escape = TRUE;
						break;
					default:
						std::cout<<
						"I am not programmed to record that key..."
						<<std::endl;
                }
			}

		}
    }

    SetConsoleMode(handle, dword);
    return 0;
}


A test code, now I shall add to my game.
