Exam 8: Modules and Functions

Sending the value of a variable or constant to a module, where a local variable is initialized to the argument's value is known as ____.

Why is it that all variables are not declared as global?

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

When output is meant for the screen, you should use the ____ keyword.

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

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

The following function has ____. Function Numeric average() // Declare variables Declare Numeric inputNum // number entered Declare Numeric quantity // numbers input Declare Numeric total = 0 // accumulated total Declare Numeric index // loop variable Declare Numeric avg // avg of numbers // Ask user how many numbers to input Display "How many numbers will you input? " Input quantity // Ask user how many numbers to input Display "How many numbers will you input? " Input quantity // Compute and return average, end function Avg = total / quantity Return avg End Function

With a ____ error, the syntax is correct so the computer can process the instruction, but it is not the correct instruction.

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.

Instead of listing all the code in the main program, your main program calls the ____.

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

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

Modules can be designed to accept more than one argument.

A(n) ____ is simply a section of a program that performs a specific task.

In the code below, why is it that the displayName() module cannot print the person's name? Start Call getInput() Call displayName() Stop Module getInput() Declare String name Display "Enter your name: " Input name End Module Module displayName() Display "Your name is: " + name End Module

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

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

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

Data sent when a module is called is a parameter.

____ are values represented as constants or variables, which are enclosed in the parentheses following the module name in the Call statement.
