Getch vs. Getche: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on February 6, 2024
getch() is a function in C that reads a single character from the keyboard without echoing it, while getche() reads a character and echoes it back to the console.

Key Differences

Getch(), a standard library function in C, reads a character from the keyboard but does not display it on the screen. In contrast, getche() functions similarly but echoes the character back to the console, making it visible to the user.

Getch() is commonly used in situations where password inputs are required, as it doesn't reveal the character typed. getche(), however, is useful for immediate feedback scenarios, like confirming key presses in real-time.

Getch() does not buffer the input, which means it reacts immediately to key presses without waiting for the Enter key. getche(), while also reacting immediately, provides visual feedback, which can be useful for interactive programs.

Getch() enhances security in sensitive inputs by preventing character display. getche() is less secure for sensitive inputs but more user-friendly for non-critical inputs where immediate feedback is necessary.

Getch() is part of the conio.h library in C, a non-standard but widely used library. getche() is also a part of this library, sharing similar utility but differing in character echo functionality.
