For loops

Before we start working,it will be good to review again construction of for loop:

For loops consists of:

  • Initialization block in which the variable-counter is declared (var i) and its initial value is set.
  • Repeat condition (i <= 10), executing once, before every iteration of the loop.
  • Refreshing of the counter (i++) – this code is executed after each iteration.
  • Body of the loop - contains random block with source code.
