1. What is dynamic loading ?
2. Difference between Dynamic Loading and reduce number of classes ?
AFAIK, reduce the number of sub classing means you don't actually code the class statically but...
I don't get what you mentioned here.
Amleto has answers my question.
I made a mistake, the bind1st and bind2nd only accepts binary functor where my member function is a unary functor and the find_if.
I switch to boost now.
I have practice the functor concepts through exercise but i encounter error for the below code.
The below is used to check whether a particular type of folder icon exist in the vector of...
