C and C++ are programming languages, but we often hear their names together, so what is the difference between the two of them? C++ has been derived as a more efficient version of the C language.
The major difference between the two is that C is a procedural language, whereas C++ is an object-oriented language. In simpler terms, this means that C does not support the concept of classes & objects. But C++ does support object-oriented features like classes, inheritance, abstraction, and many more.
C language was developed by Dennis Ritchie in 1969 and released in 1972. It is a procedural programming language and does not follow the OOPs concepts like inheritance, polymorphism, or encapsulation.
C language does not support operator overloading concepts.
Also, it is known as function-driven language.
This is lightweight and offers manual memory management.
Because C is a procedure-oriented programming language, it follows a top-down approach.
In this case, the main() function is written at first, and all subfunctions are called from the main() function.
Thereafter, sub-functions are written as per the requirements.
C language can be used when writing system level codes.
Additionally, the data in a C code behaves as a free entity and can be manipulated by outside code.
About C++ Language
C++ was developed by Bjarne Stroustrup in 1979 and made its first appearance in 1985. C++ supports both procedural and object-oriented concepts of programming. Therefore, it supports inheritance, polymorphism, and encapsulation.
The C++ programming language has almost everything that C has to offer but more effectively.
Encapsulation ensures that the data is hidden, and only the intended data is visible to an outside user.
C++ is also known as object driven language.
The C++ programming language follows a bottom-up approach.
In the bottom-up approach, the code is composed of classes and functions, and these are later integrated with the main() function.
While C++ can run most C code, the C compiler isn’t able to execute the C++ code.
C++ must be used when writing codes for networking and server-side applications.
Difference Between C And C++
C follows a top-down approach
C++ follows a bottom-up approach
Compatibility with each other
C compilers cannot execute C++ codes
C++ compilers can run C codes
Does not support encapsulation hence, not good for data security
Supports the concept of encapsulation, hence data security is assured
No such feature is offered.
C++ allows the programmer to hide variables inside a class and provide an interface only with the functions
C has 32 keywords
C++ has 52 keywords
C does not provide direct methods to handle exceptions
C++ has try and catch blocks for exception handling
Input and Output Functions
C uses scanf() function to take input from the user and printf() to print the results
C++ uses cin to take input and cout to present the output. These are operator overloaded functions
Both of C & C++ languages are among the two most basic languages for programming. Hence, it is a great time to brush up on your C and C++ skills or start developing them, if you haven’t already.
