Getch Not Working In Dev C++
Hi, I'm trying to write a while loop that is able to recognise and act on keyboard presses without pausing to wait for an input (unlike getchar). At the moment I'm just trying to detect any keypress and exit the loop by changing an integer, printing out the recorded keypress on the way out. Void main isn't legal C unless your compiler allows it as an extension. Not all compilers allow it as an extension, and that makes void main dangerously nonportable because if it's not supported, the entire program no longer has predictable behaviour. That's the theory at least. Gotoxy, clrscr, getche and getch in GCC Linux – Function definitions, calling with solved c programs/example. Gotoxy is used to move cursor position on x and y location, clrscr is used to clear the screen and getch is used to get a character from keyboard or halt/pause the program until a key hit.

-->Gets a character from the console without echo.
See kbhit just checks if there is something in the input buffer. It does not do anything else. Instead you could simply use getch which will take the charachter if its there and if not it will force the user to enter a charachter. That is the safest and most easy way to do what you are tryin to achieve. Firstly sorry for my English. I was trying to make a console game. At the end of the game I wanted to let user choose to continue game or not by selecting yes or no by using arrow keys on keyboard. But it working weirdly right now. When I pressed the arrow key, the cursor should move but it does it only for a bit and back to selecting 'yes'.

Important
This API cannot be used in applications that execute in the Windows Runtime. For more information, see CRT functions not supported in Universal Windows Platform apps.
Syntax
Return Value
Returns the character read. There is no error return.
Remarks
The _getch and _getwch functions read a single character from the console without echoing the character. None of these functions can be used to read CTRL+C. When reading a function key or an arrow key, each function must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.
These functions lock the calling thread and are therefore thread-safe. For non-locking versions, see _getch_nolock, _getwch_nolock.
By default, this function's global state is scoped to the application. To change this, see Global state in the CRT.
