4. Loops

Question 1

Loop

Answer 1

• Program construct that repeatedly executes the loop’s statements (known as the loop body)
• while the loop’s expression is true; when false, execution proceeds past the loop.

Question 2

Iteration

Answer 2

Each time through a loop’s statements is called an iteration.

Question 3

While Loop

Answer 3

• Executes while the loop repeatedly executes the loop body while the loop’s expression evaluates to true
• Exits loop when condition is false
• When the number of iterations is not known

Question 4

For Loop

Answer 4

• Consisting of a loop variable initialization, a loop expression, and a loop variable update that typically describes iterating for a specific number of times.
• When the number of iterations is known

Question 5

Nested Loop

Answer 5

• A loop that appears in the body of another loop.
• Referred to as the inner loop and outer loop

Question 6

Do-while loop

Answer 6

• First executes the loop body’s statements, then checks the loop condition.
• When the loop should iterate at least once
