meaning of these symbol?

[newbie]

i'm a newbie for c programming.
Anyone can tell me what the meaning of '<<', '>>', '&' and ' | '?

These symbols are bitwise operators.

& = AND

| = OR

<< = left shift

If you want to know what these operators do, i suggest you to read

thanks
how about this ' ->' ?

 

[jamx]

The -> symbol points to the member of some object/struct.
Like: myObject->value = 1;

No it doesn't. It dereferences a pointer to a struct (or union)
and then selects the appropriate member. To select the member of a
struct use the '.' operator.

This is no way to learn C. Get a good book on the subject.

If you have a decent textbook or tutorial, you can easily look up this
information. If you don't, you're not going to be able to learn the
language.
