 True At any moment in time, a variable can hold more than one value. (True/False) True The ability of variables to change in value is what makes computers and programming worthwhile. (True/False) True In many programming languages, if you declare a variable and do not initialize it, the variable contains an unknown value until it is assigned a value. (True/False) True Programmers generally write programs as one long series of steps. (True/False) True Most modern programming languages require that program statements be placed in specific columns. (True/False) variables; literals, or unnamed constants; and named constants When you write programs, you work with data in three different forms: Declaration In most programming languages, before you can use any variable, you must include a ____ for it. Declaring The process of naming program variables and assigning a type to them is called ____ variables. Garbage A variable’s unknown value is commonly called ____. Mnemonic You can also refer to a variable name as a ____. Camel Casing When the variable starts with a lowercase letter and any subsequent word begins with an uppercase letter, this is called ____. Pascal When the first letter of a variable name is uppercase, as in HourlyWage, the format is known as ____ casing. Numeric constant A specific numeric value is often called a ____. Floating-point Fractional numeric variables that contain a decimal point are known as ____ variables. Named constant A(n) ____ is similar to a variable, except it can be assigned a value only once. Rules of precedence The ____ dictate the order in which operations in the same statement are carried out. Modularization The process of breaking down a large program into modules is called ____. Abstraction ____ is the process of paying attention to important properties while ignoring nonessential details. Encapsulated Programmers say the statements that are contained in a module have been ____. In scope Programmers say that variables and constants declared within a module are ____ only within that module. Global ____ variables and constants are known to the entire program. Hierarchy chart When a program has several modules calling other modules, programmers often use a program ____, which operates similarly to an organizational chart, to show the overall picture of how modules are related to one another. Annotation symbol An ____ is most often represented by a three-sided box that is connected to the step it references by a dashed line. Self-documenting Programmers refer to programs that contain meaningful names as ____. Hungarian notation ____ is where a variable’s data type or other information is stored as part of the name. Temporary A ____ variable is not used for input or output, but instead is just a working variable that you use during a program’s execution. Initializing Declaring a starting value is known as ____ the variable. Keywords Each programming language has a few reserved ____ that are not allowed as variable names because they are part of the language’s syntax. Integer Whole number numeric variables are known as ____ numeric variables. Housekeeping ____ tasks include any steps you must perform at the beginning of a program to get ready for the rest of the program. Comments Program ____ are written explanations that are not part of the program logic but that serve as documentation for readers of the program. Variables Named memory locations whose contents can vary or differ over time Declaration A statement that provides a data type and an identifier for a variable Identifier A variable’s name Numeric variable Can hold digits and have mathematical operations performed on it String variable Can hold text, such as letters of the alphabet, and other special characters, such as punctuation marks Reliability The feature of programs that assures you a module has been tested and proven to function correctly Data dictionary A list of every variable name used in a program, along with its type, size, and description Prompt A message that is displayed on a monitor to ask the user for a response and perhaps explain how that response should be formatted Echoing input The act of repeating input back to a user either in a subsequent prompt or in output
