Answer / svlsr2000
Functions are boud to there address so that they could be
executed. if the address of the functions are known durning
compile time the compiler binds it, this kind of binding is
known as compile time binding or early binding. Where as
when we dont know which function needs to be exucuted
during compile time (as in case of dynamic polymorphism),
compiler uses mechaninsm of virtual table and binds the
function address during runtime. this is known as runtime
binding or late binding.
