Deck 8: Modules and Functions

Question 1

Structured programming, the method for creating all programs from sequence, selection, and repetition structures, is about clarity.

Answer 1

True

Question 2

Clumsy programming involves code that repeats throughout a program, long modules without any apparent organization, and use of the infamous GOTO statement.

Answer 2

True

Question 3

Modules cannot call other modules.

Answer 3

False

Question 4

In most programming languages, global variables are declared explicitly as global or declared in the main module outside any other modules.

Question 5

In general, variables are assumed to be global unless they are declared as local.

Question 6

All variables declared in separate modules are global and cannot be affected by other modules.

Question 7

If two variables in different modules happen to have the same name, they are stored in different memory locations, and the statements affecting one do not affect the other.

Question 8

The flowchart shape for a called module is a parallelogram with stripes, which indicates a predefined process.

Question 9

A For loop is depicted like a While loop in a flowchart, with initialization and incrementing as separate steps.

Question 10

An efficient way of providing data to modules and still allowing the use of local variables is to pass the data as an argument.

Question 11

Data sent when a module is called is a parameter.

Question 12

A parameter consists of the data type and variable pair to receive the data.

Question 13

Modules can be designed to accept more than one argument.

Question 14

Parameters and arguments must match in number, data type, and order.

Question 15

Functions can return more than one value.

Question 16

When you call a module by using an argument, you are sending data to the module.

Question 17

Functions return values by sending data back to the calling module.

Question 18

You should design your modules and functions to be capable of being used in more than one way.

Question 19

Low coupling limits a module's flexibility.

Question 20

Modularizing a program makes it more efficient by including highly cohesive code and calling another module for each separate task.

Question 21

If you have more than five to six statements that are closely related to the same purpose and have the potential of being used in more than one place in your program, you should consider turning these statements into a module.

Question 22

Modules cannot be reused in a program.

Question 23

Programmers can work on separate modules for efficiency without having to worry about variable names used in other modules.

Question 24

An advantage of modularization is that the main module is easier to understand yet still gives the "big picture" of what's happening.

Question 25

In a pseudocode class definition, if a method returns a value, the method header starts with the method name
