Time tracking : How fast is my script?

ROOT
1

_ROOT Version: 6.12
_Platform: centos 7
_Compiler: g++ --version 4.8.5

Hello, is there a way to track the time that a script needs to be carried out in the root libraries? Compiling with


> g++ -o script script.cpp `root-config --cflags --glibs`

In pyroot I simply use: import time and the time.time() command

Thanks for your answers!

void stopwatch() {
   auto timer = new TStopwatch();
   timer->Start();
   int n = 100000;
   for (int i=0; i<n; i++) {}

   cout << "Time for " << n << " iterations of an No_Op loop "<< timer->RealTime() << "s" <<endl;
}
