[C++] medir el tiempo transcurrido entre la ejecución de dos líneas de código
timeval t1, t2;
double elapsedTime;
// start timer
gettimeofday(&t1, NULL);
....
// stop timer
gettimeofday(&t2, NULL);
// compute and print the elapsed time in millisec
elapsedTime = (t2.tv_sec - t1.tv_sec) * 1000.0; // sec to ms
elapsedTime += (t2.tv_usec - t1.tv_usec) / 1000.0; // us to ms
