Jul 02, 2012 In this tutorial, I'm going to teach you the Get Character Command, which is a very good replacement for the System Pause command. 'Like-Comment-Subscribe' P. Getch is a nonstandard function and is present in conio.h header file which is mostly used by MS-DOS compilers like Turbo C. It is not part of the C standard library or ISO C, Like above functions, it reads also a single character from keyboard.
Gets a character from the console without echo.
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.
Hello.I have a newish ks9000 smart tv.I'm told it had two freeview tuners.When I go to auto tune and scan terrestrial / digital it only finds 4 garbage paytoview trailer channels.I have messed around with various scans with always the same results.I cannot find and channels at all.My ks9000 is wired and wireless connected to my virgin hub and clearly receives digital and has the internet.I do have an aerial and a cable connection elsewhere in the house but neither are wired to this primary tv. I'm told for freeview I only needed Wi-Fi which it has.I'd manually tune it if I knew the frequencies.I've googled everything and it's all confusing double talk.Please help. Auto tuning terrestrial or digital.
Returns the character read. There is no error return.
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.

Function getch in C program prompts a user to press a character. It doesn't show up on the screen. Its declaration is in 'conio.h' header file. The function is not a part of standard C library.
printf('Waiting for a character to be pressed from the keyboard to exit.n');
When you run this program, it exits only when you press a character. Try pressing num lock, shift key, etc. (program will not exit if you press these keys) as these are not characters.
Try running the program by removing getch. In this case, it will exit without waiting for a character hit from the keyboard.
cout <<'Enter a character';
Function getch works in Dev C++ compiler but it doesn't support all functions of 'conio.h' as Turbo C compiler does.
Little snitch kernel extension could not be loaded. A common use of getch is you can view the output (if any) of a program without having to open the output window if you are using Turbo C compiler or if you are not running your program from the command prompt.
