getch() takes one char from keyboard but it will be invisible to us. in other words we can say that it waits until press any key from keyboard.
getch() is a function which has its protype defined in conio.h header file.
it is basically used to take input a single characterfrom keyboard. and this char is not displayed at the screen.
it waits until itn gets a input that's why it can be used as a screen stopper.

∙ 11y ago"getch" is a function that retrieves a character from the console's standard input stream. It is considered a non-standard function of the C language that was often implemented in versions of C that were intended to be run from a terminal or command prompt.

∙ 10y agoThe getch() function returns a character from an input stream but does not echo it to the output stream. This can be useful when entering passwords as you can capture the keystroke but output an asterisk.

∙ 12y agoOnly in schoolwork programs written for Windows, DOS-mode: when you run the program from Explorer or Commander, Windows opens a separate DOS-shell for it, and automatically closes it, when the program terminates; so you wouldn't see the output if it weren't for the getch.
Actual programs (FORMAT.COM or TC.EXE, for example) don't do this, they expect you to open a DOS-shell manually (Win+R=Run: CMD.EXE)

∙ 12y agogetch is used in C (in DOS (conio.h) or unix (curses.h)), to wait for the user to press a key.
Many people (beginners mostly) that write Dos programs, and run them from Windows add a 'getch' to the end, to prevent Windows from automatically close the Dos-window.

What is the return value of getch?
getch(); is used for unbuffered input. e.x: int main() { char num=0; printf("Press a keyboard button: "); num = getch(); //This brings in 1 character that the user pressed on the keyboard printf("\nYou pressed: %c", num); //This prints the character you pressed getchar(); // I am using getchar(); to stop the program from ending after pressing buttons return 0; } My input will be within the (). output: Press a keyboard button: (v) You pressed: v EOP //End of program I hope this has helped you!
Why wont your c plus plus program stay open?
If you are talking about the program executing, but the output screen being displayed for a flash and then disappearing, I suggest adding getch() or getchar() function at the end of your main function. This will make sure that the output screen waits for you to press a character before the program terminates.
