C++ keypress: getch, cin.get?

Question

I have a Win32 program that runs on a loop. I would like to be able to pause that program while awaiting a keypress. It doesn\'t matter whether I use \'any key\' or a specif

Answer 1

HWND hwnd = ::GetConsoleWindow();

while (!((::GetForegroundWindow() == hwnd) &&
        ((::GetKeyState(VK_SPACE) & 0x8000) != 0)))
    ::Sleep(0);

Suppose it is not the best way but it solved my problem. Replace VK_SPACE with any other value you like. And it is not portable.

Answer 2

Assuming that you are looking for an alternative for getch ( which does not echo to screen).

If you are using windows and visual studio to be precise try using _getch. Here is a link to it http://msdn.microsoft.com/en-us/library/078sfkak(v=VS.100).aspx

Answer 3

Example:

#include <iostream>
#include <conio.h>

int main()
{
  std::cout << "Press any key to continue . . ." << std::endl;
  _getch(); // wait for keypress
}

_getch() is C++ equivalent to C getch()

Answer 4

You should use neither.

You should use

#include <iostream>
...
int main()
{
   ... 
   std::cin.ignore(); //why read something if you need to ignore it? :)
}'

Here's the documentation

Answer 5

Try

#include <iostream>

using namespace std;

char temp;
cin >> temp;

Answer 6

You should #include <iostream> and use std::cin.get();

I think the getch() is a C function, but since you are using C++, then the cin would be more appropriate.
