use getline():

to read the line from the file

then use rfind() and substr():

http://www.cplusplus.com/reference/string/string
http://www.cplusplus.com/reference/string/string/rfind/
http://www.cplusplus.com/reference/string/string/substr/

to extract the value from end

then you can use atof:

http://www.cplusplus.com/reference/clibrary/cstdlib/atof/

to get the double from the extracted string
