Task
Loops/For with a specified step
You are encouraged to solve this task according to the task description, using any language you may know.

Demonstrate a for loop where the step value is greater than one.

BASIC

Works with: QuickBasic version 4.5

<lang qbasic>for i = 2 to 8 step 2

  print i; ", ";

next i print "who do we appreciate?"</lang>

Java

<lang java>for(int i = 2; i <= 8;i += 2){

  System.out.print(i + ", ");

} System.out.println("who do we appreciate?");</lang>

Python

<lang python>for i in range(2, 9, 2):

   print "%d," % i,

print "who do we appreciate?"</lang> Output

2, 4, 6, 8, who do we appreciate?

Ruby

<lang ruby>2.step(8,2) {|n| print "#{n}, "} puts "who do we appreciate?"</lang> or: <lang ruby>(2..8).step(2) {|n| print "#{n}, "} puts "who do we appreciate?"</lang> Output

2, 4, 6, 8, who do we appreciate?
