Using C++ to read a data file stored in 16-bit format

Hi,


I am trying to use C++ to read a file stored in 16-bit format. It looks like :
"D6 CD 2F 01 52 07 01 00-52 07 01 00 52 07 01 00" under a hex editor.

The first variable have 4 bytes: "D6 CD 2F 01". It essentially reprents "19910102"
the second variable have 1 byte...etc.

So the problem is how to read it using C++?


THanks,
Zheng

Take a look at the iostream library to get an undestanding of how to read the files in C++
Try some code after that and if u face difficulties coe back here again

If this is a school assignment you will probably have to hack around with iostream or something, as Raghuram says.

In the real world we use fread()

Expand|Select|Wrap|Line Numbers
  1. fread(
  2.   p,        // point to buffer for storing data
  3.   4,        // size of data items
  4.   N,       // number of items
  5.   fp );     // file pointer
This works in C and C++
