Thare are many things wrong with this code

1. Did you read the posting guidelines? They're conveniently summarized next to the box where you typed your question: use [code]...[/code] tags around your code.
2. #include <iostream> not <iostream.h>
3. #include <fstream> not <fstream.h>
4. conio.h is non-standard. You don't really need it for what you're trying to do so I would avoid it alltogether
5. You're missing std:: in many places, or "using namespace std;".
6. You don't need "put" to write strings to your file. Use << instead.
7. You don't need "get" to read strings from your file. Use >> instead.
8. If you really want to use put and get, then you should check a reference for fstream: the beginning of the file is not necessarily at position 0. Use tellp first to get the position of the put pointer before writing to the file. Then seekg to this position after writing to reread the string. Note that the get and put pointers are can be at two different positions, that's why there is a seekg and seekp.
9. consider using C++ strings if you are using C++ instead of C strings.
10. You did not close your file.
