Using chrono::high_resolution_timer

Demo Code

#include <chrono>
#include <iostream>

using namespace std;

void RunTest(unsigned int numberIterations)
{
    auto start = chrono::high_resolution_clock::now();

    for (unsigned int i{ 0 }; i < numberIterations; ++i)
    {//from w w w .jav a2s.co  m
        unsigned int squared{ i*i*i };
    }

    auto end = chrono::high_resolution_clock::now();
    auto difference = end - start;

    cout << "Time taken: "
        << chrono::duration_cast<chrono::microseconds>(difference).count()
        << " microseconds!" << endl;
}

int main(int argc, char* argv[])
{
    RunTest(10000000);
    RunTest(100000000);
    RunTest(1000000000);

    return 0;
