How can I measure execution time in C++?

How can I measure execution time in C++?

You can use the <chrono> library in C++ to measure execution time. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

#include <iostream>
#include <chrono>

int main() {
    auto start = std::chrono::high_resolution_clock::now();
    // Code to measure
    auto end = std::chrono::high_resolution_clock::now();
    std::chrono::duration<double> duration = end - start;
    std::cout << "Execution time: " << duration.count() << " seconds" << std::endl;
    return 0;
}

What if I want to measure a specific function's execution time?

You can wrap the function call with the timing code. For example:

void myFunction() {
    // Function code
}

int main() {
    auto start = std::chrono::high_resolution_clock::now();
    myFunction();
    auto end = std::chrono::high_resolution_clock::now();
    // Timing code...
}
