Suppose I have a file named tenhistograms.root
In this are ten histograms: { h1,h2,h3,h4,h6,h7,h8,h11,h12,h13 }
I have a loop that analyses the histograms.
However, I want to add a for/else statement so that if a histogram is not
present, the loop will not execute, and will simply go on to check the
next histogram that does exist. Something like:
if(! 'histogram with that particular name in the file tenhistograms.root')
cout << "Error!";
else
'the loop'
Any ideas, anyone?
