What is the difference between C and C++?
Direct Answer
A fundamental question comparing a procedural language with an object-oriented extension, testing core computer science knowledge.
Why Interviewers Ask This
Understanding the evolution from C to C++ is vital for systems programming roles. It checks if you grasp the shift from procedural to object-oriented paradigms and memory management differences.
How to Answer This Question
Highlight that C is procedural while C++ adds classes, objects, and inheritance. Mention that C++ supports both styles but C does not. Discuss differences in memory management and standard libraries (STL in C++).
Key Points to Cover
- Procedural vs OOP
- Classes and Objects
- STL availability
- Memory safety features
Sample Answer
C is a procedural language focused on functions and structured programming. C++ extends C by adding Object-Oriented Programming features like classes, polymorphism, and encapsulation. C++ also provides the Standard Templ…
