Difference Between C and C++

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.

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.
