| In the expression 12 + 7, the values on the right and left of the "+" symbol are called _____. | Operands |
| An _____ operator raises a number to a power. | Exponent (^ / **) |
| A _____ operator performs division, but instead of returning the quotient it returns the remainder. | Modulus (MOD / %) |
| A _____ specifies a variable's name and data type. | Variable Declaration |
| Assigning a value to a variable in a declaration statement is called _____. | Initialization |
| An _____ variable is one that has been declared, but has not been initialized or assigned a value. | Uninitialized |
| A _____ is a variable whose content has a value that is read only and cannot be changed during the program's execution. | Named Constant |
| A debugging process in which you imagine that you are the computer executing a program is called _____. | Hand Tracing (Desk Checking) |
| Short notes placed in different parts of a program, explaining how those parts of the program work, are called _____. | Comments |
| The term _____ means to find and correct the code that is causing logic errors. | Debug |
| True/False: The Program Development Cycle repeats only 3 times. | False -- The cycle repeats until no errors can be found in the program. |
| List the five steps of the Program Development Cycle. | Design the program, Write the code, Correct syntax errors, Test the executable code, and Debug the code. |
| What two steps summarize the process of designing a program? | Understand the task that the program is to perform. / Determine the steps that must be taken to perform the task. |

| In a flowchart, what are the parallelograms known as? What do they represent? | Input Symbols + Output Symbols Represents a step in the program where data is either inputted/outputted. |
| In a flowchart, what are the rectangles known as? What do they represent? | Processing Symbols Represents a step in the program where data is processed. |
| True/False: The disadvantage of drawing flowcharts by hand is that mistakes have to be manually erased which means that the programmer might have to redraw the entire page. | True |
| In a flowchart, what symbol is a circle with a letter or number written inside it? What does it represent? | Connector Symbol Represents a bridge between two separate flowcharts that work in tangent. |
| In a flowchart, what is the "home plate" shaped symbol called? What does it do? | Off-Page Connector Symbol Connects pieces of a flowchart that is too big to fit on a single page. |

| A string that appears in the actual code of a program/pseudocode is known as a _____. | String Literal |
| True/False: Variable names can contain spaces. | False: Variable names must be one word and cannot contain spaces. |
| True/False: In most languages, punctuation characters can't be used in variable names. | True: It's best to only use alphabetic letters and numbers for variable names. |
| True/False: In most languages, the first character of a variable name can't be a number. | True |
| When writing a variable name, you can use the _____ naming convention. The first word is written with lowercase letters and then (without spaces in between) the first character of the following words are written in uppercase. | camelCase |

| True/False: A variable can hold multiple values at a time. | False: A variable can only hold one value at a time. |
| True/False: When you store a value in a variable, that value replaces the previous value that was in the variable. | True |
| A programmer's tools for performing calculations are called _____. | Math Operators |
| A _____ performs a calculation and gives a value. | Math Expression |
| What is the order of operations? | Parentheses, Exponents, Multiplication / Division / Modulus (as appeared from left to right), Addition / Subtraction (as appeared from left to right) |
| Most programming languages require that you _____ all of the variables that you intend to use in a program. | Declare |
| A variable's _____ is the type of data that the variable will hold. | Data Type |
| True/False: You have to write a variable's declaration statement after any other statements in the program that use the variable. | False: The variable's declaration statement must be written before any other statements that use the the variable. |
| True/False: A blank line in a program doesn't affect the way a program works. | True: Most compilers and interpreters ignore blank lines. |
