示例1: main
int main()
{
#ifdef __GNUC__
#ifdef __clang__
std::cout << "clang++ compiler version " << __VERSION__ << "\n";
#else
std::cout << "g++ compiler version " << __VERSION__ << "\n";
#endif
#endif
try {

std::cout << "no threading " << tNoThreads << " usecs"
<< ", " << tNoThreads * 1e-6 << " secs\n";
std::cout << "vector v size/capacity=" << app.Size() << "/" << app.Capacity() << "\n";
app.Reset(); // run adds things to vector v with push_back, reset vector v for the threaded run
