Designing loops - part 1

• What do I repeat?
  • what is the task that is to be repeated?
• What do I change?
  • what are the changes performed after each iteration?
• When do I stop?
  • when do you stop repeating?
• How do I begin?
  • what are initial conditions before the loop starts?

Hints: 

• Identify the changes: Notice what has to be changed from one iteration to the next.
• Identify the condition to execute or stop the loop.
• Identify what are initial conditions and values to be set.
