DIFFERENCES BETWEEN C AND C++


                               C                              C++
1. C is Procedural Language.1. C++ is non Procedural i.e Object oriented Language.
2. No virtual Functions are present in C2. The concept of virtual Functions are used in C++.
3. In C, Polymorphism is not possible.3. The concept of polymorphism is used in C++.
Polymorphism is the most Important Feature of OOPS.
4. Operator overloading is not possible in C.4. Operator overloading is one of the greatest Feature of C++.
5. Top down approach is used in Program Design.5. Bottom up approach adopted in Program Design.
6. No namespace Feature is present in C Language.6. Namespace Feature is present in C++ for avoiding Name collision.
7. Multiple Declaration of global variables are allowed.7. Multiple Declaration of global varioables are not allowed.
8. In C
  • scanf() Function used for Input.
  • printf() Function used for output.
8. In C++
  • Cin>> Function used for Input.
  • Cout<< Function used for output.
9. Mapping between Data and Function is difficult and complicated.9. Mapping between Data and Function can be used using "Objects"
10. In C, we can call main() Function through other Functions10. 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. No inheritance is possible in C.12. Inheritance is possible in C++
13. In C, malloc() and calloc() Functions are used for Memory Allocation and free() function for memory Deallocating.13.In C++,  new and delete operators are used for Memory Allocating and Deallocating.
14. It supports built-in and primitive data types.14. It support both built-in and user define data types.
15. In C, Exception Handling is not present.15. In C++, Exception Handling is done with Try and Catch block.

CLASSIFICATION OF OPERATING SYSTEMS

Operating systems can be classified into different types based on their interface, user friendliness, and functionality. Different types of operating systems are: Character user interface (CUI)-based operating systems Graphical user interface (GUI)-based operating systems Single-user operating systems Multi-user operating systems Single-tasking operating systems Multitasking operating systems Real-time operating systems 1. Character User Interface (CUI)-Based Operating Systems: MS-DOS and UNIX (not newer Linux) Such an interface is also called a Command-Line Interface (CLI). 2. Graphical User Interface (GUI)-Based Operating Systems GUI-based operating systems are easy to use because the user can click menus and icons rather than type cryptic commands. Users can use a device called a mouse to select an application, after which the operating system will load and run it. In comparison to a CUI-based operating system, a GUI based operating system is slower and needs ...
