An example of an AI chatbot conversation about C++ interview questions focusing on performance optimization.
What are some common C++ interview questions on performance optimization?
Some common questions include: 1. How do you measure performance in C++? 2. What are the differences between stack and heap memory? 3. Can you explain the concept of move semantics?
Can you elaborate on move semantics?
Sure! Move semantics allow the resources of a temporary object to be moved rather than copied, improving performance by avoiding unnecessary deep copies.
What tools can I use to measure performance in C++?
You can use tools like Valgrind, gprof, or even built-in profilers in IDEs like Visual Studio to measure performance.
How does memory management affect performance?
Memory management can significantly impact performance due to allocation overhead, fragmentation, and cache locality. Efficient management can reduce these issues.
