    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 .

    You might want to read the homework policy.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    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' ???
    (lser light beat me to it)
