How to go about with a 16x4 display ? pos (0,2) and (0,3) starts on position (4,2) and (4,3).

Here is the code: lcd.clear(); lcd.setCursor(0, 0); lcd.print("*** first line."); lcd.setCursor(0, 1); lcd.print("*** second line."); lcd.setCursor(0, 2); lcd.print("*** third line."); lcd.setCursor(0, 3); lcd.print("*** fourth line.");
