C and C++ are two different programming languages with some similarities but also significant differences. The Key Difference Between C and C++ is that C is a procedural programming language whereas C++ is an object-oriented programming language.
C++ supports all the features of OOP like encapsulation, inheritance, and polymorphism, while C does not have built-in support for OOP.

Comparison Chart
- C and C++ both have different features and functionalities, here is a comparison of some key features between them.
C | C++ |
---|---|
Developed by Dennis Ritchie | Bjarne Stroustrup |
Procedural Structured | Object oriented Structured. |
Top down approach | Bottom up approach |
Function and operator overloading Not Possible in C | Function and operator overloading Possible in C++ |
C is a function-driven language. | C++ is an object-driven language |
No namespace Feature | Namespace Feature is present for avoiding Name collision. |
Reference Variable Not Support | Reference Variable Support |
Polymorphism not support | Polymorphism is the most Important Feature of C++. |
Low-level language | Middle-level language |
There are 32 keywords in the C | There are 97 keywords in the C++ |
Limited memory management features | Advanced memory management features including constructors, destructors, and automatic memory management using RAII |
Faster than C++ in some cases | Slightly slower than C in some cases due to additional features |
- Overall, C and C++ are two programming languages with their own advantages and use cases.
- C is a simpler language that is well-suited for system-level programming and low-level hardware access, while C++ is a more complex and feature-rich language that is better suited for large-scale software development and complex projects.
