getchar() is a function call: it reads in a single
character and waits for the user to hit 'enter key' before
reading the character. This line is included because many
compiler environments will open a new console window, run
the program, and then close the window before you can see
the output. This command keeps that window from closing
because the program is not done yet because it waits for
you to hit enter. Including that line gives you time to see
the program run.
getch() is not waiting to press enter to show output on
screen.
but getchar() is waiting to press enter to show output.
