1.c supports build-in and primitive datatype whereas c++
supports both build-in and user-defined datatype.

2.no namespace are present in c. namespace are present in c++.

3.polymorphism is not possible in c.polymorphism is possible
in c++.

4.no virtual function are present in c.there are virtual
function in c++.

5.In c,we have to declare variables at the start.In c++ we
can declare variables at any point with in a block not just
at the begining.

6.operator overloading is not possible in c.operator
overloading is possible in c++.

7.c have no classes.c++ use classes.

8.multiple declaration of global variables are allowed in
c.multiple declarations of global variables are not allowed
in c++.

9.c supports top down parsing.c++ supports bottom of parsing.

10.in c we can call main() function through other
function.in c++ we can not call main() function through
other function
or
we can say main function could be recursive in c and it
can't be called recursively in c++.
