If Statement (Delphi and C++ Cross Reference Guide)

Notice in the more complete example that the semicolon for the begin..end block after end is not included. That tells the compiler something else is coming (the statement is not finished). Also note the semicolon is missing right before the final "else" statement.

Note: The following example uses floating point literals. In Delphi, to specify a fractional floating point literal between 1 and -1, you preceed the decimal with a 0; otherwise, you will get a compiler error (i.e. .1 + .1 does not work).

if (0.1 + 0.1 + 0.1) = 0.3 then
  ShowMessage('Correct')
else
  ShowMessage('Not correct');

//Complete example:
if x = true then
begin 

  ShowMessage('x is true');

end

Else If y = 'Mike' Then 

  ShowMessage('hello mike')

Else 

  ShowMessage('last option');

 Delphi If Statement (If..Else If..Else)

Same as standard C.

//C++Builder example using the VCL ShowMessage.

int x;

x = 8;

if (x == 10) {
  ShowMessage("x is 10.");
} else if (x < 10) {
  ShowMessage("x is less than 10.");
} else {
  ShowMessage("x must be greater than 10.");
}
