Learn about more differences and similarities between C and C++ from here. Question 2: What is a static variable? Answer: Static variables have a property of preserving their value even after they are out of their scope! Hence, static variables preserve their previous value in their previous scope and are not initialized again in the new scope. Question 3: Are Variables in C static or Dynamic scoped? Answer: Variables in C are always statically scoped. Visit How are variables scoped in C – Static or Dynamic? to learn more. Question 4: Explain the four storage classes in C?

In the Technical Round, the interviewer was friendly and began by asking me to briefly explain my final year project — its objective, tech stack, and how I contributed. I was then asked core CS questions including: Concepts of OOPs like inheritance, polymorphism, abstraction, and encapsulation. Inline functions: what they are and their purpose in C++. A simple coding question to swap two variables without using a third variable. The questions were conceptual and tested my understanding rather than just memory.
