Looping entries doesn't show any values

[Nep_Neeraj]

Hello all,

I tried to loop a list of root files using vector and each root file has similar ttree, from each ttree I want to plot and extract some values. But after loading each root file and reading them, temptree->Show(4) shows the entry values but when it is looped through GetEntry(), it shows zero. I wonder anyone here finds out the problem with the script test.C (1.6 KB) ? Thanks in advance.
