Assuming this isn't homework, in the package Ada.Text_IO (ARM A.10.1)
you will find the generic packages Integer_IO and Modular_IO (described
in more detail in ARM A.10.8). If you look at the Put procedures, you
will find the parameter Base. This allows you to specify the number base
to represent the number in. If you supply the value 2 for Base, you will
get the number output in binary.

A typical value from Put with Base => 2 might be " 2#10101010#". If you
need to get rid of the leading " 2#" and the trailing '#', you can use
the Put that writes to a String and manipulate the result.
Alternatively, you can use an Image function from PragmARC.Images, which
does it for you.

So, in Ada it is not necessary to convert the value to an array of bits
(which could be accomplished with Ada.Unchecked_Conversion), nor to
output the bits individually. Yet another case where Ada is simpler and
more expressive than other languages.
