The provided code snippet has the following purpose:

char ch;

ch = getch();

1. Declaration of a character variable: char ch; defines a variable ch of type char to hold a single character.

2. Calling getch(): The function getch() is used to read a single character input from the keyboard. It does this without requiring the user to press the Enter key. The character entered is stored in the variable ch.

   • getch() is typically found in <conio.h> (a console I/O library available in some C compilers, such as Turbo C or older MS-DOS environments).
   • It performs unbuffered input, meaning the character is immediately returned by the function without being displayed on the console unless explicitly printed later.

Summary:

This code waits for the user to press a key, retrieves the pressed character using getch(), and stores it into the variable ch. The character will not be echoed (displayed) on the screen.
