Lets first see what
is delegate.
If you will say delegate always one thing is come into our
mind, a function pointer calling as an argument.
But it’s no sense with this Definition its showing the
concept of use of delegate it won’t say why we need it and when we need this
delegate.
For this we need to check with the English meaning of
delegate, a representative. e.g Indian delegate go to US to deal something.
So this representative will give the time to time details of
the operation and this delegate is the wrapper for our India which we hide but
to present to the US also.
