Hi Bhaskar, > One of the errors I encountered was : > <filename>.cc:64:23: error: strstream.h: No such file > or directory strstream.h is not part of C++. (Some early pre-standard C++ implementations included strstream.h, but it was cut from by the committee in favor of stringstreams.) Use <sstream> instead. Keep in mind that you won't need the ends manipulator, and you won't have to manage the memory of the stream's backingstore like you had to do with <strstream.h>. HTH, --Eljay
