How is Getch implemented in Linux?

getch() and getche() for GCC Linux: getch() is declared in conio. h header file. getche() function is used to get (read) single character from standard input device (keyboard) with echoing i.e. it displays the input character & it does not require [return] key after input. getche() is declared in conio.

What is use of conio h in C++?

h is a C header file used mostly by MS-DOS compilers to provide console input/output. It is not part of the C standard library or ISO C, nor is it defined by POSIX. This header declares several useful library functions for performing “istream input and output” from a program.

How do you hold console in C++?

You can also lean on the IDE a little. If you run the program using the “Start without debugging” command (Ctrl+F5 for me), the console window will stay open even after the program ends with a “Press any key to continue . . .” message.

What can I use instead of getch in C++?

There isn’t a direct replacement in standard C++. For getch(), int ch = std::cin. get(); is probably the closest equivalent — but bear in mind that this will read from buffered standard input, whereas I think the conio. h getch does an unbuffered read.

What is the purpose of Getch in C++?
