Delphi		There are two forms of if statement: // if...then if x<>0 then // do something // if...then...else if x=0 then // do something else // do something another begin end pair can be used: if x=0 then begin // do something end else begin // do something another end; ; cannot be placed before else: if A>B then AProc; < illegal! else BProc if statements can be nested: if S='Greatis Software' then GoToLink('http://www.greatis.com') else if S='Microsoft' then GoToLink('http://www.microsoft.com') else GoToLink('http://www.google.com');
C#		C# has very similar if statement: // if...then if (x<>0) then // do something // if...then...else if (x=0) then ;// do something else // do something another Complex operators can be used with "{}": if (x=0) then { // do something } else { // do something another } And if can be nested too: if (S="Greatis Software") then GoToLink("http://www.greatis.com"); else if (S="Microsoft") then GoToLink("http://www.microsoft.com"); else GoToLink("http://www.google.com");      Place condition into parentheses and do not place ";" before else.
