What are the benefits of count-controlled iteration?
What are the benefits of count-controlled iteration?
- It results in more programming errors
- It is less flexible than other iteration methods

Study Notes
- Iteration is the repetition of a segment of code.
- Loops are areas of code that are repeatedly executed.
- Count-controlled iteration executes a section of code a fixed number of times.
- The for and next statements are used in count-controlled iteration.
- The condition variable keeps track of how many times the code has been repeated.
- The count value increases by one every time the code is iterated.
- The iteration ends when the count value equals the finish value.
- The condition variable can be used inside the loop itself.
- Count-controlled iteration results in fewer programming errors and more flexibility.
- Iteration simplifies programs and makes them less prone to errors.
