Rules for do-while loop:

Statements in do-while are executed repeatedly executed as long as condition is true.The moment condition is false,control goes out of do-while loop and statements outside the loop are executed.

It is post tested loop or exit tested loop that is condition si tested at the end of loop.Hence do-while loop is executed at least once.There is semicolon( after condition, it indicates that end of do-while loop.

NOTE:
Use for loop,while loop,do-while loop to execute a group of statements repeatedly until condition is false
