|Exercise: Trying Interactive ROOT|
|On an interactive ROOT session: Fill an array of 100 000 000 64Bit floating point numbers of the machine independent ROOT type |
Hint: You can get random real numbers by creating a pointer to an instance of the
TRandom *R = new TRandom(time(0)); // create a pointer to a new instance of TRandom in the heap cout << R->Rndm() << endl;
|Exercise: Interpreted ROOT Macros|
|Exercise: Compiled ROOT Macros|
|Use the script you've written before and modify it so it can be run as compiled macro via ACLiC.
|Exercise: A Simple Stand-Alone Application|
|Once again, consider the code you should have previously written to compute the mean of an array of random numbers. Now, last but not least, make it a stand-alone application and run it independently of any ROOT session. Make sure that passing parameters will still work. Check the performance of your application. Take also care that your modifications don't disturb interpretation or on-the-fly compilation by CINT or ACLiC.|
