FOR counter = startNumber TO endNumber
                        Statements to repeat
                        Increase or decrease the counter variable
                 END
                 Where

                     the counter is a variable that keeps count of the number of times the instructions inside the
                     loop have been executed.
                    the startNumber is the starting number of value of the loop.
                    the endNumber is the total number of times the loop must run.

                 Let us see a program to understand the concept of FOR...NEXT statement.

















                                                        Printing numbers 1 to 15
                 This program prints the numbers from 1 to 15 in order. The concept of increasing the value of

                 a variable is used in programming very often. So, most of the programming languages have a
                 simpler and easier way to do this. In the preceding example, the variable i contains a value that
                 increases by 1 each time the loop runs.
                 Sample Programs Using For...Next Statement


                 Program 1: To print even numbers up to 30.















                 Program 2: To print all odd numbers from 1 to 24.
