How to make a class in C++ work in ROOT, instead

[spyhunter01]

Can anybody tell me how to make this code work in ROOT?

myclass2.cpp (371 Bytes)

My second question is about files with .C extension. Can they only for loading in ROOT but not like standalone codes to run?

Thanks.

Replace “main” with “myclass2”, then try root [0] .x myclass2.cpp

For C++ source code, you can use e.g. “.cxx”, “.cpp”, “.C”.

ı forgot to change this main part. You are right. However, it still doesn’t work.

My error: warning: cannot find function ‘myclass2()’; falling back to .L

It’s kind of telling me that ı can only load this but not run by using .x myclass2.cpp++

Why is it doing this for .cpp++ option?
