Advantage of C++ over C

C++ keeps the speed and low-level power of C but adds features that make large programs safer, easier to write and easier to maintain. Advantages of C++ over C:

1. Object oriented support - classes, objects, inheritance and polymorphism allow real-world modelling; C has only functions and structures.
2. Data security - encapsulation and access specifiers hide data. In C, structure members are open to all.
3. Reusability - inheritance and templates let existing code be reused.
4. Function and operator overloading - one name for related operations, and natural syntax for user-defined types such as c1 + c2.
5. Better I/O - cin and cout need no format specifiers and are type safe.
6. Safer memory handling - new and delete with constructors and destructors, instead of malloc() and free().
7. Exception handling - structured run-time error handling with try, catch, throw.
8. Extra constructs - references, default arguments, inline functions, namespaces, and the STL.
9. Easier maintenance of large programs - modular classes reduce complexity.
