what is the main difference between c and c++?

Answer Posted / sumit gupta , bangalore

In object oriented programming, the programmer can solve
problems by breaking them down into real-life objects (it
presented the programmer with an opportunity to mirror real
life). What is an object? This topic is dealt with
extensively in the chapter on ‘Objects and Classes’ but a
brief introduction is provided here.

Consider the category of cars. All cars have some common
features (for example all cars have four wheels, an engine,
some body colour, seats etc.). Are all cars the same? Of
course not. A Fiat and a Ford aren’t the same but they are
called as cars in general. In this example cars will form a
class and Ford (or Fiat) will be an object.

For those people who know C programming, it would be useful
to know the differences between C and C++. Basically C++
includes everything present in C but the use of some C
features is deprecated in C++.

*C does not have classes and objects (C does not support
OOP)
*Structures in C cannot have functions.
*C does not have namespaces (namespaces are used to
avoid name collisions).
*The I/O functions are entirely different in C and C++
(ex: printf( ), scanf( ) etc. are part of the C language).
*You cannot overload a function in C (i.e. you cannot
have 2 functions with the same name in C).
*Better dynamic memory management operators are
available in C++.
*C does not have reference variables (in C++ reference
variables are used in functions).
*In C constants are defined as macros (in C++ we can
make use of ‘const’ to declare a constant).
*Inline functions are not available in C.
