You are trying to open signal.dat from ROOT’s tree tutorials directory, which might not be where the file is stored. You can use in.is_open() to check if the input has been successfully opened.

How can I read a text file from my current directory where this basic.C file is there ?

You specify the path in ifstream::open().
