This is the thirteenth in
This is the thirteenth in a series of computer science video tutorials for beginners, about programming with Visual Basic.NET (VB.NET) in Visual Studio. In this lesson you will learn how to execute a block of code repeatedly using the FOR NEXT construct. This illustrates the third fundamental construct of high level programming, namely iteration. Iteration is also known as looping. You will see how FOR NEXT automatically increments the contents of a variable which serves to count the number of passes through the loop. Indeed, FOR NEXT loops are sometimes referred to as count controlled loops. You will also see how the number of increments with each pass of the loop can be controlled by means of the STEP clause, and how you can even decrement the counter variable.
