In-case this is my last fully updated code my search seems to have some problem as I have explained before.It's a bit confusing so I tried to make it as readable as possible.

         cout<<"enter employee number:";
         cin>>empno;
         cout<<"enter employee name:";
          gets(name);

I suppose that you pressed <Return> after writing the number.
`name' is empty, all the subsequent input is corrupted.
http://www.cplusplus.com/forum/beginner/114875/#msg627086

Also, pour acid on your editor, it's awful indenting code.
Same goes for your compiler
The headers are `iostream' and `fstream' without the .h
There are namespaces. `cout' `cin' `fstream' are in the std namespace.
main must return int.
¿is it right and just to use conio.h?
gets() is deprecated

[cyberdude]

ya i am using turbo c++ but could you tell me whats wrong with my search options didint get you correctly

[ne555]

your input is incorrect, then you are searching garbage.

[cyberdude]

what do you suggest as an alternative

[nvrmnd]

you can use cin.getline() instead:

cout<<"enter employee number:";
cin>>empno;

cin.ignore(); // to ignore '\n'

cout<<"enter employee name:";
cin.getline( name, 25, '\n' );
// name -> variable to store  the input
// 25 -> since your name array is 25 characters wide,
//       getline() will only store up to 24 characters + '\0'
//       to name. ( to prevent overflows )
// '\n' -> the delimiter, getline() will stop reading after encountering this

// ...
