Both getch() and getche() are used to read single character
there is very little difference
-getch() doesn't display output to screen if used without lvalue
-getche() display output to screen even if used without lvalue

following example will clear this.....
1.
main()
{
getch();
}
2.
main()
{
getche();
}
after running above programs...............
when you press any key, you'll exit from output screen
verify the output by pressing alt+F5
1. will not show anything
2.will show the key you were pressed......
hope you get it.............
