Answer 17

Question 18

True or false? A for loop is an exit condition loop. If false, explain why.

Answer 18

Question 19

True or false? Because a for loop is an entry condition loop, the third clause inside the parentheses is executed at the beginning ofeach iteration. If false, explain why.

Answer 19

Question 20

True or false? A return statement is used to terminate a method and (optionally) return a value to the calling method. If False, explain why.

Question 21

Answer 20

True.

Back to Question 20

Answer 19

False. Although the third clause appears physically at the top of the loop, it isn't executed until the statements in the body of the loop have completedexecution. This is an important point since this clause is typically used to update the control variable, and perhaps other variables as well. If variablesare updated in the third clause and used in the body of the loop, it is important to understand that they do not get updated until the execution of thebody is completed.

Back to Question 19

Answer 18

False. The value of the second clause is tested when the statement first begins execution, and at the beginning of each iteration thereafter. Therefore,the for loop is an entry condition loop.

Back to Question 18

Answer 17

False. The second clause consists of a single expression which must eventually evaluate to false (not true) to cause the loop to terminate.

Back to Question 17

Answer 16

True.

Back to Question 16

Answer 15

Typically the first clause is used for initialization. The intended purpose of the first clause is initialization.

Back to Question 15

Answer 14

False. The expressions in the first clause are executed only once, at the beginning of the loop, regardless of the number of iterations.

Back to Question 14

Answer 13

The comma operator guarantees that its left operand will be executed before its right operand.

Back to Question 13

Answer 12

True.

Back to Question 12

Answer 11

The general syntax of a for loop follows:

Syntax of a for loop for (first clause; second clause; third clause) single or compound statement

Back to Question 11

Answer 10

False: A for loop header consists of three clauses separated by semicolons, not colons.

Back to Question 10

Answer 9

The operation of a loop normally involves the following three actions in addition to executing the code in the body of the loop:

  • Initialize a control variable.
  • Test the control variable in a conditional expression.
  • Update the control variable.

Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
