Q regarding a strange behavior when using ifstream

[Pinux]

Hi,

I now run into a very strange behavior when using ifstream. Can anyone please help me out here:

Basically, what I want to do is to encrypt a plain text file into a cipher text and then decrypt it back to the plain text file. I use ifstream to read the file into the buffer. Let's say the size of my encrypted file is 816 bytes. Normally after opening the file and calling the inf.read(garbage, 16), the get pointer should be moved from the ios::beg forward 16 bytes and therefore length is equal to 16. This is the result I get from when running this code against the plain text file. But things are different when I use this code to read the encrypted file. After opening the encrypted file and calling the inf.read(...), length is equal to 672. If I call the inf.read(...) again, then the get pointer moves 16 bytes forward and length is equal to 688. How come the get pointer jumps directly to the position 672?

Thanks

my code:

char garbage[16];
int length;
 
ifstream inf;
inf.open("fileName");
inf.read(garbage, 16);  
length = inf.tellg();

Have you tried opening the encrypted file as binary??
