What are some examples of benchmarking in C++14?

C++14 introduced several features that can enhance benchmarking. For example, you can use the std::chrono library for precise timing.

Can you show me a simple code example using std::chrono?

Sure! Here's a simple example:

#include <iostream>
#include <chrono>

void functionToBenchmark() {
    // Simulate some work
    for (int i = 0; i < 1000000; ++i);
}

int main() {
    auto start = std::chrono::high_resolution_clock::now();
    functionToBenchmark();
    auto end = std::chrono::high_resolution_clock::now();
    std::chrono::duration<double> duration = end - start;
    std::cout << "Duration: " << duration.count() << " seconds" << std::endl;
    return 0;
}

This code measures the time taken by functionToBenchmark.

What other libraries can I use for benchmarking?

You can also use libraries like Google Benchmark, which provides a rich set of features for benchmarking C++ code.

How do I install Google Benchmark?

You can install Google Benchmark via package managers like vcpkg or by building it from source. Would you like instructions for a specific method?
