C# Language Basics

End of Statement

Languages Focus

In coding languages, common End of statement specifiers include a semicolon and return (others exist too). Also of concern when studying a language is can you put two statements on a single code line and can you break a single statement into two or more code lines.

C#:   ;

C# uses a semicolon ";" as an end of statement specifier and you can put multiple statements on a single line of code if you wish as well as split a single statement into two or more code lines.

Syntax Example:  
Console.WriteLine("Hello1");
Console.WriteLine("Hello2");
Console.WriteLine("Hello3");

//Same line works too:
Console.WriteLine("Hello4"); Console.WriteLine("Hello5");
 
//Two or more lines works too: 
Console.
  WriteLine
("Hello6");





Cross Reference Examples:

Access VBA:   Return

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Syntax Example:
MsgBox "Hello1"
MsgBox "Hello2"
MsgBox "Hello3"

'The following commented code on a single line does not work...
'MsgBox "Hello4" MsgBox "Hello5"

'Two or more lines works too with a space+underscore:
MsgBox _
"Hello6";
ASP Classic:   Return

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Syntax Example:
Response.Write("Hello1")
Response.Write("Hello2")
Response.Write("Hello3")

'The following commented code on a single line does not work...
' Response.Write("Hello4") Response.Write("Hello5")

'Two or more lines works too with a space+underscore:
Response.Write _
("Hello6")
C++:   ;

C++ uses a semicolon ";" as an end of statement specifier and you can put multiple statements on a single line of code if you wish as well as split a single statement into two or more code lines.

Syntax Example:
printf("Hello1");
printf("Hello2");
  
printf("Hello3"); printf("Hello4");
  
printf
   ("Hello5");
C++/CLI:   ;

Same as standard C++. C++ uses a semicolon ";" as an end of statement specifier and you can put multiple statements on a single line of code if you wish as well as split a single statement into two or more code lines.

Syntax Example:
//.Net WinForms example.
//Add, using namespace System::Windows::Forms;
MessageBox::Show("Hello1");
MessageBox::Show("Hello2");
MessageBox::Show("Hello3");
   
MessageBox::Show("Hello4"); MessageBox::Show("Hello5"); 
  
MessageBox:: 
  Show 
    ("Hello6");
Corel Paradox:   whitespace

ObjectPAL is a bit unique in that it doesn't use a semicolon nor a return to mark the end of a line, it uses whitespace which can be a return, space, or tab. This is a bit unusual but does allow for some nice formatting of code.

Syntax Example:  
msgInfo("", "Hello1")
msgInfo("", "Hello2")
msgInfo("", "Hello3")

;The following single line of code also works.
msgInfo("", "Hello4") msgInfo("", "Hello5")

;Two or more works too:
msgInfo
("", "Hello6")
Delphi:   ;

Object Pascal uses a semicolon ";" as an end of statement specifier and you can put multiple statements on a single line of code and put a single statement on two or more code lines if you wish.

Syntax Example:  
WriteLn('Hello1');
WriteLn('Hello2');
WriteLn('Hello3');

//Same line works too:
WriteLn('Hello4'); WriteLn('Hello5');

//Two or more lines works too:
WriteLn
('Hello6');
Delphi Prism:   ;

Object Pascal uses a semicolon ";" as an end of statement specifier and you can put multiple statements on a single line of code and put a single statement on two or more code lines if you wish.

Syntax Example:  
MessageBox.Show("Hello1");
MessageBox.Show("Hello2");
MessageBox.Show("Hello3");

//Same line works too:
MessageBox.Show("Hello4");  MessageBox.Show("Hello5");

//Two or more lines works too:
MessageBox.Show
("Hello6");
Java:   ;
Syntax Example:
System.out.println("Hello");
JavaScript:   ; is optional

In JavaScript, using a semicolon at the end of statements is optional. You might think a semicolon then is just another comment specifier but it is not. The semicolon is an optional end of statement specifier. To put two statements on a single code line, you must use a semicolon. However, the semicolon is optional, but probably confusing, when you break a single statement into multiple code lines.

Syntax Example:
document.write("Hello1");
document.write("Hello2");

//Semicolons are optional:
document.write("Hello3")
document.write("Hello4")

//This works too but only if you use a semicolon:
document.write("Hello5"); document.write("Hello6");

//Two lines also works:
document.write
("Hello7")
Perl:   ;
Syntax Example:
print "Hello";
PHP:   ;
Syntax Example:
echo "Hello";
VB Classic:   Return

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Syntax Example:
MsgBox "Hello1"
MsgBox "Hello2"
MsgBox "Hello3"

'The following commented code
'on a single line does not work...
'MsgBox "Hello4" MsgBox "Hello5"

'Two or more lines works too with a space+underscore:
MsgBox _
"Hello6";
VB.Net:   Return

A return marks the end of a statement and you cannot combine statements on a single line of code. You can break a single statement into two or more code lines by using a space and underscore " _".

Syntax Example:  
Console.WriteLine("Hello1")
Console.WriteLine("Hello2")
Console.WriteLine("Hello3")

'The following commented code
'on a single line does not work...
'Console.WriteLine("Hello4") Console.WriteLine("Hello5")

'Two or more lines works too with a space+underscore:
Console.WriteLine _
"Hello6";
