writing 10 gives 10 and 13

[thepenguin77]

I am trying to write numbers to a binary file. The problem that I have is when I try to write a 10 it is preceded by a 13. I believe that this has something to do with the program thinking that I want to put in a return.

When I write:

newFile.put(26) ;
newFile.put(10) ;
newFile.put(0);

and hex dump. The result is:
1A 0D 0A 00
That 0D shouldn't be there.

Is there a better way to write numbers to file or a way to stop this from happening? Also I need the numbers in this order since a different program will be using the file.

I'll assume that you are using ofstream objects, if so put takes a char as a argument,not an int.If you have opened your file in binary mode,just use << operator to write your data into the file.

Ok, So I would use
newFile << 26 << 10 << 0;

And I'm using fstream if it makes a difference.

Edit: It didn't work, I opened it with ios::binary and when I used << it just put the ascii code in the file.

The operator<< formats the values you write; use the put() or the write() functions for unformatted output. Have a look here.

I found the problem. When I was using write() and put() I didn't have it set to binary.
