I'm following a tutorial at http://cplusplus.com/doc/tutorial/tut1-3.html and the problem is that I don't understand the description of an operator called module (%).

The description that they give there is I believe got a mistake (I just don't know what mistake).

The only one that may not be known by you is the module, specified with the percentage sign (%). Module is the operation that gives the rest of a division of two integer values. For example, if we write a = 11 % 3;, the variable a will contain 2 as result since 2 is the rest from dividing 11 between 3.
That was from that site, and I don't get it?

Anyone? PLS HLP

2. % does an integer division, throws away the quotient and returns the remainder.
/ does an integer division, throws away the remainder and returns the quotient.

21/5 = 4
21%5 =1

get it?

3. If you are doing normal devision using a paper and a pencil... You'll get two things:
The result, and the remainder...
The / operator will give you the result, and the & operator will give you the remainder.

What is it that is not clear?

4. no no, its clear all-right!

thanks but could I get some more examples.
