What is the difference between benchmarking and profiling in C++?
Benchmarking measures the performance of a program or algorithm, while profiling analyzes resource usage during execution.
Can you give me examples of tools used for each?
For benchmarking, tools like Google Benchmark and Catch2 are popular. For profiling, you might use gprof or Valgrind.
When should I use benchmarking over profiling?
Use benchmarking when you want to compare performance metrics, and profiling when you need to identify bottlenecks in your code.
Are there any best practices for benchmarking in C++?
Yes, ensure your benchmarks are isolated, repeat them multiple times, and avoid optimizations that can skew results.
