What happens if in while loop test expression?

What’s the difference between a for loop while loop and if statement?

While loops are best used when you don’t know exactly how many times you may have to loop through a condition – if you know exactly how many times you want to test a condition (e.g. 10), then you’d use a for loop instead. An if statement will execute once if a condition is true.

Is a while loop always an indefinite loop?

The while loop executes the block of code until the condition is true.

We mostly use while loop when we don’t know how many times the loop will actually execute at runtime.

In simple terms when iterations of a loop are known then we mainly use for loop and when iterations are unknown then we use while loop.

What is an example of while loop?

A while loop is a control flow structure which repeatedly executes a block of code indefinite no. of times until the given condition becomes false. For example, say, you want to count the occurrence of odd numbers in a range. Some technical references call it a pre-test loop as it checks the condition before every iteration.
