Difference Between C and C++

C	C++
1. C is Procedural Language.	1. C++ is non Procedural i.e Object oriented Language.
2. In C, Polymorphism is not possible.	2. The concept of polymorphism is used in C++.Polymorphism is the most Important Feature of OOPS.
3. Inheritance is not possible in C.	3. Inheritance is possible in C++.
4. Virtual Functions are not present in C.	4. The concept of virtual Functions are used in C++.
5. Operator overloading is not possible in C.	5. Operator overloading is one of the greatest Feature of C++.
6. Top-down approach is used in Program Design.	6. Bottom-up approach adopted in Program Design.
7. Multiple Declaration of global variables are allowed.	7. Multiple Declaration of global varioables are not allowed.
8. scanf() Function used for Input. printf() Function used for output.	8. Cin>> Function used for Input. Cout<< Function used for output.
9. Namespace Feature is not present in C.	9. Namespace Feature is present in C++ for avoiding Name collision.
10. In C, we can call main() Function through other Functions	10. In C++, we cannot call main() Function through other functions.
11. C requires all the variables to be defined at the starting of a scope.	11. C++ allows the declaration of variable anywhere in the scope i.e at time of its First use.
12. In C, malloc() and calloc() Functions are used for Memory Allocation and free() function for memory Deallocating.	12. In C++, new and delete operators are used for Memory Allocating and Deallocating.
13. C supports built-in and primitive data types.	13. C++ support both built-in and user define data types.
14. Mapping between Data and Function is difficult and complicated.	14. Mapping between Data and Function can be used using Objects
