How can I detect if any key is pressed by the user in C++ (console)?

Question

I am writing a C++ CLI application how can I detect if any key is pressed by the user. I've seen that in c# but how can it be implement in c++

while(1)
     {
      while(/* code to check if any key is pressed*/)
           {        //rest of the code
                    // sleep function
           }
     }

Hint: like in CLI games to move or to take certain action when a key is pressed or don't do any thing if no input is given.

Solution

we can use _kbhit() function in c++. _kbhit is equal to 1 if any key is pressed. You have to clear the _kbhit buffer else it will remain 1. Method for clearing is character = getch(); This will save the last entered key in character which you can compare and decide which action to perform on which key.
