Like many programming languages out there, VB 6 also has loop control statements. In this article, you will learn about While loop which helps in repeating a block of code until loop is terminated.
Syntax: While Loop
The general structure of while loop is given below.
While condition
[expression or statements]
Wend
The condition is very important in while loo
p because that is what decides when the loop will be terminated.
Consider the example below.
Dim index As Integer
index = -1;
While index < 10
MsgBox (index + 2)
Wend
In the example above, we have put a condition for while
loop that the loop should continue until index
variable is equal to or greater than 10.
Example Program:
Dim Sum As Integer, i As Integer
i = 0;
While i < 10
Sum = Sum + i
i = i + i
Wend
MsgBox ("The Value of Sum is " + Sum)
Output – While Loop
The program loop through and add the value of i to Sum
which is incremented by 1
at each iteration.
