Just set a counter called c. When a wrong password is entered increment the counter by one. When it reaches 3 just exit using any functions like exit(0) or System.exit(0) if you use C language and Java.

Answer 2

Ask the manufacture or the programmer who made the software, god only knows what you are using.
