c++ time a function code example

Example 1: time function c++

/* Answer to: "time function c++" */

#include <chrono> 
using namespace std::chrono; 

auto start = high_resolution_clock::now(); 
auto stop = high_resolution_clock::now(); 
auto duration = duration_cast<microseconds>(stop - start); 
  
cout << duration.count() << endl;

Example 2: time function c++

#include <chrono> 
using namespace std::chrono; 

auto start = high_resolution_clock::now(); 

// perform function to be timed here...

auto stop = high_resolution_clock::now(); 
cout << duration_cast<microseconds>(stop - start).count() << endl;
