It depends on what you mean by "character array".  If you are talking  
about a variable declared like so:

char myarray[32];

Then to get the address, you would do the following:

print("The address is %p\n", (&myarray));

If you are talking about a variable declared like:

char *myarray = new char[32];

Then the address is stored in 'myarray', and de-referencing 'myarray'  
will give you the actual contents of the string.
