count

Syntax:

   #include <boost/bit_logic/bit_container_type.hpp>

Note: These functions are equivelant for all bit_container types. `bit_array<N>, bit_vector, bit_container_adaptor`

The count() function counts the number of bits set inside of a bit_container.

For example:

 bit_array<9> a ;
 a = "110011001" ; 
 cout << a.count() << endl ;

This code would produce this output:

Count function can throw throw exceptions on empty containers.

Exceptions:

Zero sized bit containers
