Bitwise operators

Jul 7th, 2003

Anybody understand these? I'm having the hardest time with them. Partly because I don't see a use for them

But what would be an example of a time when you would need to operate on a bit itself? As in, what is their purpose?
Thanks for any help

Most of the time you don't need to use the bitwise operations. The only time I've had to operate with bits is combining the modes in the ifstream/ofstream constructors:

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
ifstream in( "myfile.txt", ios::in | ios::binary ) ;
ifstream in( "myfile.txt", ios::in | ios::binary ) ;

Also when I dealt with bitmaps and transparency, I had to use masking and it involved bitwise knowledge.

ok, thanks. Then I'll just read through them and get a basic understanding. I just wanted to know if I would be needing them quite often, so then I would need a full grasp of them.
But thanks!
