Later i want read this file and fill the tree is there any library available for that? or is there any simple and fast way to do this please sugget

In C you'd use fread and fwrite and in C++ you'd use std::istream::read and std::ostream::write to save plain old data (POD) structures without pointers to a file. All the functions I've mentioned read and write raw bytes so if you want a human readable file you'll have to use something else e.g. use formatted I/O in C and the stream insertion/extraction operators in C++.

simplest way are fwrite and fread.
WriteFile and ReadFile APIS are another options. :)
