* C does not have any classes or objects. It is
procedure and function driven. There is no concept of access
through objects and structures are the only place where
there is a access through a compacted variable. c++ is
object oriented.

* C structures have a different behaviour compared to
c++ structures. Structures in c do not accept functions as
their parts.

* C input/output is based on library and the processes
are carried out by including functions. C++ i/o is made
through console commands cin and cout.

* C functions do not support overloading. Operator
overloading is a process in which the same function has two
or more different behaviours based on the data input by the
user.

* C does not support new or delete commands. The memory
operations to free or allocate memory in c are carried out
by malloc() and free().

* Undeclared functions in c++ are not allowed. The
function has to have a prototype defined before the main()
before use in c++ although in c the functions can be
declared at the point of use.

* After declaring structures and enumerators in c we
cannot declare the variable for the structure right after
the end of the structure as in c++.

* For an int main() in c++ we may not write a return
statement but the return is mandatory in c if we are using
int main().

* In C++ identifiers are not allowed to contain two or
more consecutive underscores in any position. C identifiers
cannot start with two or more consecutive underscores, but
may contain them in other positions.

* C has a top down approach whereas c++ has a bottom up
approach.

* In c a character constant is automatically elevated to
an integer whereas in c++ this is not the case.

* In c declaring the global variable several times is
allowed but this is not allowed in c++.
