Code Editor

The _______ window helps you locate and fix the syntax errors in your code; however, it cannot locate any errors in your code

Code editor

The process of locating and correcting any bugs in a program is called_______ a. exterminating b. debugging c. compiling d. linking

Debugging

Decimal

While stepping through a program in the debugger, the ______ statements are skipped over because they are not considered executable in the debugger a. ff b. next c. for d. dim

Dim

The______ window provides a description of of each error and the location of each error in the code a. code b. error List c. project d. solution

Error List

Window that displays a list of error messages

Error List Window

Provides a description of each syntax error and the location of each syntax error in the code

Error Message

T/f: Logic errors are the easiest to find

False

T/f: One advantage of variables and named constants is that their use requires fewer lines of code

False

T/f: Stepping through code one line at a time is the only way of searching for logic errors

False

T/f: The error list window displays a red rectangle next to each error in the code

False

T/f: Unlike logic errors, syntax errors are much more difficult to find because they do not trigger an error message from the code editor

False

T/f: When a text box control is empty, or when it contains a character that cannot be converted to a number, the TryParse method will store a blank string

False

T/f: You can only use variable memory locations to control the data type of numbers used in calculations

False

In the code editor window, the ______ alert you that lines contain a syntax error a. jagged red lines b. thin blue boxes c. thick red boxes d. jagged blue lines

Jagged Red Lines

A _____ error can occur for a variety of reasons, such as forgetting to enter an instruction or entering the instructions in the wrong order a. syntax b. function c. computer d. logic

Logic

Entering instructions in the wrong order in a program can cause a ______ error a. logic b. sequential c. function d. compostion

Logic

You use a(n) _______ to pause program execution at a specific line in the code

breakpoint

A(n) ______ is an error in a program's code

bug

While stepping through the code, the ________ highlights the statement that will be executed next

debugger

The process of locating and fixing error in a program is called ________

debugging

the process of locating and correcting any bugs in a program

debugging

An .0 at the end of a number indicates that the number's data type is

double

A(n) _______ error is an error that can occur for a variety of reasons, such as forgetting to enter an instruction, entering the instructions in the wrong order, or entering a calculation statement that is incorrect mathematically

logic

an error that can occur for a variety of reasons, such as forgetting to enter an instruction

logic error

A(n) _______ error is an error that occurs while the application is running

run time

A ______ error occurs when you break one of the language's rules

syntax

T/f: A run time error is an error that occurs while an application is running

True

T/f: As the amount of code increases, so does the likelihood for errors

True

T/f: Both constants and variable memory locations make your code more self-documenting and easier to understand

True

T/f: Many run time errors can be avoided using the selection structure

True

T/f: Program bugs typically are caused by either syntax errors or logic errors

True

T/f: Some logic errors occur as a result of calculation statements that are correct syntactically, but incorrect mathematically

True

T/f: When debugging, while the execution of a procedure's code is paused, you can view the contents of controls and variables that appear in the highlighted statement, as well as in the statements above in the procedure

True

T/f: You can use variables to store the value of processing items, which do not appear in the user interface

True

Most syntax errors are the result of ______ errors that occur when entering instructions a. typing b. automatic c. computer d. system

Typing

In the Code Editor window, _______indicates some suggestions for fixing errors a. red jagged lines b. blue jagged lines c. red rectangles d. blue rectangles

Red Rectangles

Program bugs are typically categorized as syntax errors, logic errors, or ________ errors a. debug b. run time c. compiler d. program

Run Time

An error that occurs while the application is running

Run Time Error

Tells the computer to execute the highlighted instruction in debug mode so you can step through the code in the Code Editor window

Step Into

The set of rules you must follow when using a programming language is called the language's ________ a. syntax b. rules c. order d. object

Syntax

__________ errors are listed in the error list window

Syntax

The error that occurs when a statement breaks one of the programming language's rules

Syntax Error

The statement constant intNUM_STUDENTS As Integer is an example of a ______ a. correct statement b. logic error c. run time error d. syntax error

Syntax Error

Which type of error will trigger an error message to be listed in the Error List window? a. logic error b. run time error c. syntax error d. none of the above

Syntax Error
