what format is the binary file? What do you want the text to look
like.
For instance the binary could be an executable and the text file
might be a hex dump or the binary might be a word processor
document and the text an ASCII dump of the text of the document.
The possibilities are endless. But the answer is yes in princple.
If you can find fred.

haha, I made a mistake here, I mean fread....but it seems fread does
not working....
fread() will almost certainly work on any reasonable
implementation. Please post your code and explain
why you think fread() is "not working".

Thank you guys~ I modified the program like the below but the new
generated txt file is a little less then the original dat file. Is
that reasonalble? I think it is not right Thank you ~~~
