String Concatenation

[Other Languages] 
Delphi:  "String Concatenation" +

Use the + operator to concatenate two strings. Use IntToStr to convert an integer to a string and FloatToStr to convert a floating point number to a string.

Syntax Example:
var 
  FirstName : String; 
  LastName : String;
begin 
  FirstName := 'Mike'; 
  LastName := 'Prestwood';
  ShowMessage('Full name: ' + FirstName + ' ' + LastName);
  
  ShowMessage(FloatToStr(3.2));
end;
Access VBA:  "String Concatenation" & or +

Although you can use either a & or a + to concatenate values, my preference is to use a + because more languages use it. However, if you use & then some type conversions are done for you. If you use + you will sometimes have to cast a value to concatenate it. For example, you will have to use CStr to cast a number to a string if you use the + operator as a concatenation operator.

Syntax Example:
Dim FirstName As String
Dim LastName As String
 
FirstName = "Mike"
LastName = "Prestwood"
 
MsgBox "Full name: " & FirstName & " " & LastName
 
MsgBox "2+2=" + CStr(2+2)
