The document discusses syntax errors in code and how Visual Studio helps identify them. It provides examples of code with syntax errors like a missing "End While" statement. Visual Studio detects these errors and tells the developer exactly where in the code the problem occurs, even identifying the specific line. It concludes by defining a syntax error as an error in the syntax or structure of code written in a programming language, such as missing or incorrectly written code elements.

1. SYNTAX ERRORS
DUH!

2. We Can Make Mistakes in Code Too
Sub Main()
Dim stopProgram As String I though I
stopProgram = "no"
dun did this
While stopProgram = "no"
ok . . .
Console.WriteLine("HA HA!")
Console.WriteLine("HA HA!")
Console.WriteLine("HA HA!")
Console.WriteLine("Do you want to stop?")
stopProgram = Console.ReadLine()
Console.WriteLine("GOODBYE!")
Console.ReadLine()
End Sub
End Module

3. We Can Make Mistakes in Code Too
Sub Main()
Dim stopProgram As String
stopProgram = "no"
That’s better!
While stopProgram = "no"
Console.WriteLine("HA HA!")
Console.WriteLine("HA HA!")
Console.WriteLine("HA HA!")
Console.WriteLine("Do you want to stop?")
stopProgram = Console.ReadLine()
End While
Console.WriteLine("GOODBYE!")
Console.ReadLine()
End Sub
End Module

4. Visual Studio Will Tell You When
You’ve Made a Mistake

5. Visual Studio Will Tell You When
You’ve Made a Mistake
Visual Studio has found that the While state has not been
closed with an End While

6. Visual Studio Will Tell You When
You’ve Made a Mistake
Visual Studio will tell you where the error can be found.
The line the
code can be
found
Be careful! You may have to dig around the code to see
EXACTLY where the problem comes from

7. Visual Studio Will Tell You When
You’ve Made a Mistake
This is
Line 8 . . .
. . . But
this is
where the
code is
missing

8. Visual Studio Will Tell You When
You’ve Made a Mistake
You don’t to count the lines yourself
Visual Studio has a line counter

9. We call this type error a . . .
SYNTAX
ERROR

10. Syntax Error Definition:
In computer science a syntax
error refers to an error in the
syntax of a sequence of
characters or tokens that is
intended to be written in a
particular programming
language.

11. Syntax Error Definition:
IF . .
•YOU’VE MISSED SOMETHING OUT
•YOU’VE TYPED SOMETHING
WRONG
•YOU’VE WRITTEN SOMETHING IN
THE WRONG ORDER
YOU HAVE JUST MADE A SYNTAX
ERROR!
