Difference Between C vs C++
C is a system programming language. It is also referred to as a procedural programming language. It was designed and developed by Dennis Ritchie. It was first released in the year 1972. It supports the static, manifest, nominal and weak typing. It supports cross-platform. The file extensions for this language is ‘.c’ and ‘.h’.
C++ is termed as middle-level language means the combination of features of high level and low-level programming languages. It was designed and developed by Bjarne Stroustrup in the year 1979. It was first appeared or released in 1985. It is also referred to as object-oriented programming language. It is compiled, case-sensitive and statically typed. The filename extensions are ‘.cc’, ‘.c++’ etc.
In C++, class and object are mainly used for writing programs. The class generally specifies the structure of data. It can be defined as the blueprint that describes the states of supported types. For e.g. the details of the student in student class like student’s age, name, address, etc. in one block that is class. An object is the instance of a class and it can have states and behaviors. Once the object has been created by the class, you can easily access the defined members of that class with help of an object.
As C++ is an object-oriented language, we use access modifiers to declare the methods, variables, and functions. Access modifiers are referred to as the keywords that are used to set the accessibility of classes, function, methods and other members. There are only 3 access modifiers for C++ that are: 1. Public 2. Private 3. Protected
Public: The members or fields that are declared as public can be accessed outside the class as well.
Private: The members or fields that are declared as private cannot be accessed outside the class. They can be accessed only inside the class.
Protected: The members or fields that are declared as protected can be accessed outside the class but only in a class derived from that class.
C++ follows the concept of object-oriented programming. The features or concepts of OOP are Abstraction, Encapsulation, Inheritance, and Polymorphism.
Abstraction: – It is used for hiding the internal implementations and displays only the required details to the user. Abstraction can be implemented with help of abstract class or interface. For e.g. Calculator. In the calculator, it shows only output whatever input is given. How the calculations are done, that is not necessary detail for the user.
Encapsulation: – It is referred to as data hiding. It is a mechanism that binds the data and operations together and hides that details from the user. Encapsulation can be achieved with help of access modifiers that are public, private and protected in C++. With help of them, we can provide access or prevent the access directly to a user.
Inheritance: – It is referred to as the process of creating new classes from existing classes. It means to inherit the properties of the parent class by the child class. The parent class is also called as Base class and child class is also referred to as a Derived class. Inheritance is used mainly for code reusability and to extend the parent classes.
Polymorphism: – It refers to many forms. It mainly describes as when a member function is called, it will execute the different function depending on the type of object that to invoke the function.

Below is the top 6 difference between C vs C++
Key differences between C vs C++
Both C vs C++ are popular choices in the market; let us discuss some of the major Difference Between C vs C++:
- In C, there is no featured to support namespace. In C++, it supports the feature of a namespace.
- In C, scanf and printf function are used for input and output. In C++, cin and cout functions are used for input and output.
- C does not support the function overloading. C++ does support the function overloading.
- C cannot use the access modifiers. C++ has that feature to use access modifiers and it is of 3 different types that are private, public and protected.
- C provides the malloc() and calloc() for memory allocation. C++ provides the new operator to allocate the memory.
- Error handling or exception handling is not handled in C or C does not provide support to exception handling. C++ provides support for exception handling. Its mainly done using try and catch block.
- C does not support reference variables. C++ does support reference variables.
- C does not support virtual and friend functions. C++ does support both virtual and friend functions.
- C programs are generally divided into procedures and modules. C++ programs are generally divided into functions and classes.
- C language provides good performance. C++ provides better performance compared to the C language.
C vs C++ Comparison Table
The primary Comparison between C vs C++ are discussed below:
|The Basis Of Comparison Between C vs C++||
|Definition||C is a procedural programming language.||C++ is a procedural and object-oriented programming language.|
|Programmed||C compiler is written in C and assembly language.||C++ compiler written in C++ and C language|
|Developed||C was developed by Dennis Ritchie in the year 1972.||C++ was developed by Bjarne Stroustrup in the year 1979.|
|Functions||C does not support functions.||C++ does support functions.|
|Approach||C generally follows the top-down approach.||C++ generally follows the bottom-up approach.|
|Security||In C, data is less secured.||In C++, data is more secure as we can use modifiers to restrict the user access.|
Conclusion – C vs C++
In the above C vs C++ article of, both C vs C++ is having the same base for programming. C is the first ever language ever we can say in the history of development, where we can give the input and get the output as we required. It was the revolution in the computer or information technology field. After that C++ makes the programming easier to understand and develop.
C vs C++ both are the main languages to develop the new compilers and languages. These both C vs C++ languages are easy to learn and write. C++ can be called a hybrid language. These are base of any developer and new people to start with programming, and most importantly any interviewer to start with concepts like features of OOPs. The above difference between C vs C++ give you a better idea and learn the things. Happy Learning!!!
