This is the problem in the code and please make sure highlight thecode you made changes.
if car was manufactured year for e.g. 2002 and was purchased2004. This make sense in normal lives. In program if i putmanufactured year for e.g. 2004 and purchased year 2002, how canthis make sense. Manufactured year is alway older or equal topurchased year.
