Introduction
This post is my result of the exercise 1a submitted by @lemouth in his post Particle physics @ Utopian - Detecting particles at colliders and implementing this on a computer
Post Body
After following @lemouth instructions and implementing a one liner in the Execute method template, here is the output that I get.

As you can see the program appears to run properly but some errors are reported at startup.
Please let me know in your comments if you know what the problem might be.
The code couldn't be any simpler:
bool test_analysis::Execute(SampleFormat& sample, const EventFormat& event)
{
cout << "Photons: " << event.rec()->photons().size() << ", "
<< "Electrons: " << event.rec()->electrons().size() << ", "
<< "Muons: " << event.rec()->muons().size() << endl;
...
}

Series Backlinks
This is the first post in this series.
Yes, this was very simple and you did it in the most compact possible way. However, I want to move slowly as I have no clue about the level of everyone. The next exercise will be slightly harder ;)
Of course. That makes sense.
Update: I have created this github repository to store all contributions. Can you please add yours following the
ex1a-irelandscape.cppsyntax (I only need the c++ file)? Thanks in advance!Hi @lemouth, not 100% familiar with github.
Do I need to have permissions to be able to push commits to your repository?
Or should I create a fork first?
I gave you writing rights for this folder. Please let me know whether it works.
It doesn't seem to be working at the moment:
You must first accept the invitation that I sent you through github.
Thanks, that was the problem.
I've pushed the change now.
