Loops

Front 1

What are the three types of loop statements?

Back 1

While, do-while, and for loops

Front 2

Define the following syntax:
while (loop-continuation-condition) {
//Loop body
Statement(s);
}

Back 2

It is the syntax for a while loop

Front 3

How does the do-while loop execute?

Back 3

The do-while loop executes the loop body first, then checks the loop-continuation-condition to determine whether to continue or terminate the loop

Front 4

What is a counter-controlled loop?

Back 4

A loop that is controlled by a control variable

Front 5

What is a one-time execution of a loop body referred to as?

Back 5

An iteration of the loop

Front 6

How do you "think before coding"?

Back 6

Think how you would solve the problem without writing a program

Front 7

What are the three steps to consider when writing a loop?

Back 7

Step 1: Identify the statements that need to be repeated
Step 2: Wrap these statements in a loop like this:
while (true) {
Statements;
}
Step 3: Code the loop-continuation-condition and add appropriate statements for controlling the loop

Front 8

What is a sentinel-controlled loop?

Back 8

A loop that uses a sentinel value to control it's execution

Front 9

What is a sentinel value?

Back 9

A special input value that signifies the end of a loop

Front 10

How does the while loop execute?

Back 10

The while loop repeatedly executes the statements in the loop body when the loop-continuation-condition evaluates to true

Front 11

Define the following syntax:
do {
//Loop body
Statement(s);
while (loop-continuation-condition);

Back 11

It is the syntax for the do-while loop

Front 12

When is it best to use a do-while loop versus a while loop?

Back 12

Use the do-while loop if you have statements inside the loop that must be executed at least once

Front 13

Define the following syntax:
for (initial-action; loop-continuation-condition; action-after-each-iteration) {
//Loop body;
Statement(s);
}

Back 13

It is the syntax for the for loop

Front 14

How does the for loop execute?

Back 14

A for loop performs an initial action once, then repeatedly executes the statements in the loop body, and performs an action after an iteration when the loop-continuation-condition evaluates to true

Front 15

What is a control variable?

Back 15

A variable that controls how many times the loop body is executed and when the loop terminates

Front 16

What are some for loop variations?

Back 16

Front 17

What is a pretest loop?

Back 17

The while loop and for loop are called pretest loop because the continuation condition is checked before the loop body is executed

Front 18

What is a posttest loop?

Back 18

The do-while loop is called a posttest loop because the condition is checked after the loop body is executed

Front 19

What is a nested loop?

Back 19

Nested loops consist of an outer loop and one or more inner loops
