Can you declare variable in while loop?

Can you declare variable in while loop?

You can put a variable declaration in the test expression of a while loop. What you cannot do is put a declaration statement in other expressions. For instance, in the expression a+b+c, you cannot replace b by int i = f() .

Can we initialize in while loop?

My understanding that the loop scope is between the braces {} and cannot be used to define a loop counter, because the declaration and the initialization will be redone each time.

How do you initialize a while loop?

Three things you need to successfully write a while loop:

1. INITIALIZE the loop control variable before the while loop.
2. TEST the loop control variable in the logical expression.
3. MODIFY the loop control variable in the body of the while loop.
4. count controlled while loop – you know how many pieces of data you are to read.

Can a variable be initialized in a loop?

You can’t Initialize a Variable in a loop, but you can change the value using Set Variable or Increment Variable inside a loop. If I have answered your question, please mark your post as Solved.
