The do while loop checks the condition at the end of the loop. This means that the statements inside the loop body will be executed at least once even if the condition is never true. The do while loop is an exit controlled loop, where even if the test condition is false, the loop body will be executed at least once.

When would you use a for loop?

How do you make a while loop in Visual Basic?

Visual Basic Do-While Loop Syntax If you observe the above syntax, Do-While loop starts with Do keyword followed by the block of statements and While with a parameter called boolean_expression. Here, the statements of Do-While loop will be executed first, after that the boolean_expression will be evaluated.
