Module 3 Self Test

Given the following pseudocode, what is the value of score after the call to the curveScore module?Module main() ​Declare Integer myGrade = 93 ​Call curveScore(myGrade) End ModuleModule curveScore(Integer score) ​Declare Integer newScore ​Set newScore = score + 5 ​Display newScore ​Set score = 0 End Module

0

To create a module, you write its ________.

Definition

A module can have two or more variables with the same name because they are within the same scope.

False

In most languages a module definition has three parts: a header, body, and footer.

False

The scope of the parameter variables is the entire program and they are visible to any statement in the program.

False

When a variable is passed by value, changes to that argument made within the module also affect the value of the variable in the part of the program that made the call to that module.

False

Which of the following is not a benefit of using modules when developing a program?

Programs which contain modules always run faster than programs without modules.

Given the following pseudocode, what, if anything, is an error?Module main() ​Declare Integer myGrade = 93 ​Call curveScore(myGrade) End ModuleModule curveScore(Integer score) ​Declare Integer newScore ​Set newScore = score + 5 ​Display newScore ​Set myGrade = 0 End Module

The variable myGrade is not available inside the curveScore module.

A hierarchy chart does not reveal details of the steps taken inside the module.

True

An attempt to pass a non-variable argument into a reference variable parameter will cause an error.

True

Modules can be written for commonly needed tasks, and those modules can be incorporated into each program that needs them.

True

The arguments in a module call and the parameters listed in the module header must be of compatible data types.

True

The scope of a variable is the segment of the program in which the variable can be accessed.

True

The top-down design process is sometimes referred to as stepwise refinement.

True

When a variable is passed by reference to a module, changes to the value of the argument in the module will also affect the variable in the part of the program that sent that argument.

True

Which of the following would a programmer use to visualize the relationship between modules?

a hierarchy chart

reference

Given the following pseudocode, which is the parameter?Module main() ​Call curveScore(82) End ModuleModule curveScore(Integer score) ​Declare Integer newScore ​Set newScore = score + 5 ​Display newScore End Module

score

An argument that is passed by ________ is not affected by a change to the content of the parameter variable.
