how to insert apostrophe in delphi string

To insert an apostrophe in a Delphi string, you can use two consecutive apostrophes. Here's an example:

var
  myString: string;
begin
  myString := 'I''m Delphi'; // Inserting an apostrophe in the string
  ShowMessage(myString);
end;

In the above example, the string 'I''m Delphi' will be displayed as I'm Delphi when the ShowMessage function is called.

This technique is used to escape the apostrophe character and include it as part of the string literal. By using two consecutive apostrophes, Delphi treats the second apostrophe as a literal character and not as the end of the string.
