Writing code for line numbers in Programm C++

I have been trying to find out the solution. I received the message from
CFanatic

Quote In Turbo C++, you can mark any line by #line LINE_NUMBER “FILE_NAMEâ€. You can get any line number just by click on that line and then you can write that line number in coding of C++ program. You can mark any line from any file just by using this code. Unquote

I do not find any code for that.

 

You don't need to create a thread for that and you should the existing one here - http://www.cfanatic.com/topic4563/#post8817
