In C++ its used for printing and getting input with cout, 'cout <<
"Message"; '
and more generally for bit shifting left, <<, or right, >>.

> 2) What the operator & does and what is it's use in programming
It returns the address of the variable, so
#include<stdio.h>
void main(void)
{
        int     a;
        int     *pointa;

        a=10;
        printf("a=%d\n", a);

        pointa=&a;			/* pointa contains the address of a*/
        *pointa=99;		/* a now equals 99 */
        printf("a=%d\n", a);
}

Your going to have to know alittle about assembly if you want to use
interupts.
Theres a command that lets you use registers directly, it should tell you
this
in the FAQ.

Tried it, but they wernt interested, they only get books that would be read
buy
more than a dozen of people, yours may be different of course.

Try may make shift web site, the schools
http://www.rmplc.co.uk/eduweb/sites/marl/Liam.html
and this one may be of some use, its a bit more orientated towards Assembly
