All the major difference between C and C++, that’s what i am going to tell you. Before that, let’s learn some history about C and C++.
The programming language “C”, was developed and introduced by Dennis Ritchie in 1972. C is a structure oriented programming language, most of it’s featured were derived from Basic Combined Programming Language, also know as BCPL.The main implementation area of C was UNIX operating system. In 1983, the ANSI or American National Standards Institute, founded a committee to provide a modern and comprehensive definition for C, later known as “ANSI C”.
C++ was developed by Bjarne Stroustrup starting in 1979, at famous Bell Labs. C++ is an object oriented programming (OOP) language and it’s actually an extension of C language. C++ also pronouns as “C-Plus-Plus”.
Now, i am going to list all the major difference between C and C++.So, let’s take a look.
All the major difference between C and C++
| C | C++ |
| C is a structural or procedural programming language or Procedural programming paradigm | C++ supports both procedural and object oriented programming paradigms. Mainly, Object Oriented Programming (OOP). |
| C is not Object Oriented Programming Language. Therefore it do not support Encapsulation, Inheritance, Polymorphism | Support Encapsulation, Inheritance, Polymorphism |
| Based on Procedure (Steps) to solve any problem | Based on objects rather than procedures |
| In C, functions and data are separate and free entities ( This is due to it’s procedural programming language nature) | In C++,functions and data are encapsulated as an object. Class provides the structure of an Object |
| Fundamental building blocks are Procedures | Fundamental building blocks are Objects |
| Data, manipulated outside the code. Because this information hiding/encapsulation not possible | Encapsulation, encapsulates the data to make ensure that data structures and operators are used as intended |
| C, uses Top Down Approach | C, uses Bottom Up Approach |
| C, is a Function driven language | C++, an Object driven language |
| scanf() and printf() functions for std input and output | cin>> and cout<< for std input and output |
| C, not supports Function and Operator overloading | C++, Supports both Function and Operator overloading |
| In C, Variables defined at the beginning. | In C++, Variables can define anywhere in the function |
| In C, Do not allow Functions inside Structures | In C++, Allow Functions inside Structures |
| Namespace are not possible | Namespace are possible |
| Do not support Reference variables | Supports Reference Variables |
| Middle Level Language | High Level Language |
| Do not support Virtual and Friend functions | Support both Virtual and Friend functions |
| In C, Programs are divided into modules and functions | In C++, Programs are divided into classes and functions |
malloc() and calloc() functions are used for dynamic memory allocation. Also, free() for memory de-allocation |
new operator for memory allocation. Also, free operator for memory de-allocation |
| Doesn’t support exception handling directly | Supports exception handling. By using try and catch block |
| Uses extention “.C” for saving file | Uses extention “.CPP” for saving file |
