  1. What are loops and how we can use them?

    In general a loop is a sequence of statements which is specified once but which may be carried out several times in succession. The function of the loop is to repeat the calculation a given number of times until it reaches a certain value. The code inside the loop is obeyed a specified number of times, or once for each of a collection of items, or until some condition is met, or indefinitely. We can divide loops into:
    1) Count-controlled loops,
    2) Condition – controlled loops,
    3) Collection - controlled loops,
    4) General iteration,
    5) Infinite loops,
    6) Continuation with the next iteration,
    7) Redo the current interation and
    8) Restart loop
