Difference between c and C++

C C++

1. C is a procedure oriented programming C++ is a object
oriented programming

2. C uses #include<stdio.h> C++ uses #include<iostream.h>

3. In C main focus is on functions In C++ main focus is on
data rather than functions. Data is not freely moved around
the system rather the functions exists in the object are the
only means by which the data can be accessed

4. In C No Data security In C++ data is hidden and is
secure from unauthorised access

5. In C there is no concepts like encapsulation,
polymorphism , inheritance etc. C++ provide encapsulation,
polymorphism, inheritance etc.
