What type of iteration is used in While Loop

While loop uses a type of iteration known as "Indefinite" or "Conditional" iteration.

Here's the step by step explanation:

1. Initialization: Before the loop starts, we initialize a variable that we will use for the condition.

2. Condition: This is a boolean expression that the program checks before each iteration of the loop. If the condition is true, the loop will continue to run. If it is false, the loop will stop.

3. Loop Body: This is the code that is executed on each iteration of the loop, as long as the condition is true.

4. Update: At the end of each loop iteration, we update the variable that we are using in the condition. This is usually done to gradually make the condition false, so that the loop doesn't run forever.

In summary, while loop uses indefinite or conditional iteration because it keeps iterating as long as the condition is true. It doesn't have a definite number of iterations in advance.
