Explanation:
#include <stdio.h>
: Includes the standard input/output library for functions like printf.#include <conio.h>
: Includes the console input/output library for functions like getch().int main() { ... }
: Main function where the program execution begins.int ch;
: Declares an integer variablech
to store the input character.while(1) { ... }
: Infinite loop to continuously read keyboard input.ch = getch();
: Reads a character from the keyboard and stores it in the variablech
.if(ch == 0 || ch == 224) { ... }
: Checks if the character is a special key.ch = getch();
: Reads the next character to determine the specific arrow key.switch(ch) { ... }
: Evaluates the value ofch
to determine the arrow key pressed.case 72:
: Checks if the up arrow key (ASCII code 72) is pressed and displays a message.case 80:
: Checks if the down arrow key (ASCII code 80) is pressed and displays a message.case 75:
: Checks if the left arrow key (ASCII code 75) is pressed and displays a message.case 77:
: Checks if the right arrow key (ASCII code 77) is pressed and displays a message.default:
: Executes if none of the arrow keys are pressed, displaying a generic message for other keys.return 0;
: Indicates successful execution and termination of the main function.
