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 any key
1. will not show anything
2.will show the key you were pressed......
