Loops
- C.
Circles
Correct Answer
B. LoopsExplanation
When you code with a while and for, you are using loops. Loops are used in programming to repeat a specific block of code until a certain condition is met. The while loop will continue executing the code block as long as the specified condition is true. The for loop, on the other hand, is used to iterate over a sequence of values and execute the code block for each iteration. Both while and for loops are essential in controlling the flow of execution in a program and allowing repetitive tasks to be automated.Rate this question:
