VB Prog Ch 3 Variables, Constants, and Calculations

Term	Definition
Arguments	items within parentheses after the name of either a method or a procedure; represents information that the method or procedure needs to perform its task(s)
Class scope	the scope of a class-level memory location (variable or named constant); refers to the fact that the memory location can be used by any procedure in the form class’s declarations section
Class-level named constants	a named constant declared in a form class’s declarations section; it has class scope and should be declared using the keywords Private Const
Class-level variables	a variable declared in a form class’s declarations section; it has class scope and should be declared using the keyword Private
Const statement	the statement used to create a named constant
Declaring a memory location	reserving a location in the computer’s main memory for use within an application’s code
Demoted	the process of converting a value from one data type to another data type that can store only smaller numbers or numbers with less precision
Dim statement	the statement used to declare procedure-level variables Enter event
Flowchart	a planning tool that uses standardized symbols to illustrate the steps a procedure must take to accomplish its purpose
Flowlines	the lines connecting the symbols in a flowchart
Form class’s declarations section	the area located between the Public Class and End Class clauses in the Code Editor window; class-level memory locations are declared in this section
Format	specifying the number of decimal places and the special characters to display in a number treated as a string
Implicit type conversion	the process by which a value is automatically converted to fit the data type of the memory location to which it is assigned
Input/output symbol	the parallelogram in a flowchart
Integer division operator	represented by a backslash (\); divides two integers and then returns the quotient as an integer
Lifetime	indicates how long a variable or named constant remains in the computer’s main memory
Literal type character	a character (such as the letter D) appended to a literal for the purpose of forcing the literal to assume a different data type (such as Decimal)
Modulus operator	represented by the keyword Mod; divides two numbers and then returns the remainder of the division
Named constant	a computer memory location where programmers can store data that cannot be changed during run time
Private keyword	used to declare class-level memory locations (variables and named constants)
Procedure scope	the scope of a procedure-level memory location (variable or named constant); refers to the fact that the memory location can be used only by the procedure that declares it
Procedure-level named constants	named constants declared in a procedure; the constants have procedure scope
Procedure-level variables	variables declared in a procedure; the variables have procedure scope
Process symbols	the rectangles in a flowchart
Promoted	the process of converting a value from one data type to another data type that can store either larger numbers or numbers with greater precision
Pseudocode	a planning tool that uses phrases to describe the steps a procedure must take to accomplish its purpose
RAM	random access memory
Random access memory	the main memory of a computer
Scope	indicates where a memory location (variable or named constant) can be used in an application’s code
SelectAll method	used to select all of the text contained in a text box
Start/stop symbol	the ovals in a flowchart
Static keyword	used to declare a static variable
Static variable	a procedure-level variable that remains in main memory and also retains its value until the application (rather than its declaring procedure) ends
String	a sequence of characters (numbers, letters, special characters, and so on)
String.Empty	the value that represents the empty string in Visual Basic
TextChanged event	occurs each time the value in a control’s Text property changes
ToString method	formats a copy of a number and returns the result as a string
TryParse method	used to convert a string to a specified numeric data type
Variable	a computer memory location where programmers can temporarily store data, as well as change the data, during run time

When a value is converted from one data type to another data type that can store larger numbers the value is said to be ____?

After declaring a named constant, you can refer to that constant using its name later in the program. When a value is converted from one data type to another data type that can store larger numbers, that value is said to be demoted.

Which of the following is a computer memory location whose value does not change during run time?

A constant is a data item whose value cannot change during the program's execution.

What is the primary difference between a variable and a named constant in C++?

Simply put, a variable is a value that is changing or that have the ability to change. A constant is a value which remains unchanged. For example, if you have a program that has a list of 10 radii and you want to calculate the area for all of these circles.

Which type of structure makes a decision based on one or more conditions?

Which type of structure makes a decision based on one or more conditions? The selection structure is also referred to as an iteration.
