i need help in random access files

hello ,, please i need to answer this question :

PHP Code:

---

 struct Item 
  { 
      int ID ;
     char Name[20];
     float Prices;
     int Quant;
  }; 


---

1- write a function that receives a raondom access file , Item ID . The
function will add 5 to Q

2- write a function that receives random access file , an argument , and
ask for an item ID and information to the item to the files .

* i am using borland C++
:confused:

You might want to read the homework policy.

you can use std::fstream read(), write() functions to get and write the structure.
use seekg(), seekp(), tellg(), tellp(), for random access.
I belive there is an faq item on this...

P.S. your question sounds like 'do my homework' ???
