false
It is not possible to increment a counter variable by any value other than 1.

false
Programmers must be careful not to make syntax errors when writing pseudocode programs.
false
Programming languages have not yet started to support localization.
false
Programs are commonly referred to as hardware.
false
Programs that use an interpreter generally execute faster than compiled programs because they are already entirely translated into machine language when executed.
false
Pseudocode could be logically incorrect if not properly indented.
false
The Do-While loop is a pretest loop.
false
The If-Then-Else statement should be used to write a single alternative decision structure.
false
The While loop gets its name from the way it works: While a condition is false, do some task.
false
The While loop will never execute if its condition is true to start with.
false
The code for a library function must appear in a program in order for the program to call the library function.
false
The expressions (a + b) / c and a + b / c will always yield identical results.
false
The library functions in every programming language have the same function names and accept the same arguments, but their behaviors might differ slightly.
false
The number of arguments that can be passed to a function are limited in most programming languages.
false
The scope of the parameter variables is the entire program and it is visible to any statement in the program.
false
The short-circuit evaluation is performed with expressions containing any logical operators.
false
The term software refers to all the physical devices or components that a computer is made of.
false
The toInteger function accepts a real number as its argument and preserves any fractional part in the returned number.
false
Today, CPUs are huge devices made of electrical and mechanical components such as vacuum tubes and switches.
false
Windows Vista, Linux, UNIX®, and Mac OS X are all examples of application software.
false
You cannot display the contents of the counter variable in the body of a loop.
false
A hierarchy chart does not show the steps that are taken inside a module.
true
A nested decision structure can achieve the same logic as a case structure.
true
A nested decision structure can be used to test more than one condition.
true
A sequence of characters that is used as data is called a string in programming.
true
A variable is a storage location in memory that is represented by a name and can hold different values during the execution of the program.
true
An attempt to pass a non-variable argument into a reference variable parameter will cause an error.
true
An interpreter is a program that both translates and executes the instructions in a high-level language program.
true
Any piece of data that is stored in a computer's memory must be stored as a binary number.
true
Complex mathematical expressions can sometimes be simplified by breaking out part of the expression and putting it in a function.
true
Decision structures are also known as selection structures.
true
Each instruction written in a high-level programming language is called a statement.
true
In a case-insensitive comparison, the strings "yoda" and "YODA" are equivalent.
true
In a math expression, multiplication and division take place before addition and subtraction.
true
In a nested loop, the inner loop goes through all of its iterations for every single iteration of the outer loop.
true
In an expression with an OR operator, it does not matter which sub expression is true for the compound expression to be true.
true
In most programming languages, you cannot have two variables with the same name in the same scope.
true
In some languages you must use a library function to raise a number to a power.
true
It has been proven by a group of mathematicians that all programs can be written using only three structures.
true
Module names should be as short as possible.
true
Modules can be called from statements in the body of any loop.
true
Modules can be written for commonly needed tasks, and those modules can be incorporated into each program that needs them.
true
Most programming languages do not automatically print spaces between multiple items that are displayed on the screen.
true
Most programming languages let you assign an integer value to a real variable without causing an error.
true
Programmers start writing code as the first step when they begin a new project.
true
Programmers use pseudocode to create "mock-ups" of programs because they do not have to worry about syntax rules.
true
Programming languages typically require that arguments be of the same data type as the parameters that they are passed to.
true
RAM is a volatile memory used for temporary storage while a program is running.
true
Random numbers are useful in simulation programs where the computer must randomly decide how an object will behave.
true
The "If-Then-Else If" statement can be used to simplify a complex nested decision structure.

true
The hierarchy chart does not reveal any details of the steps taken inside the module.
