Answer 1

● Left shift operator works like this:

x << y equals to x * 2^y
2 << 2 equals to 2 * 2^2
equals to 2 * 4
equals to 8

● Right shift operator works like this:

x >> y equals to x / 2^y
8 >> 2 equals to 8 / 2^2
equals to 8 / 4
equals to 2

Also you have syntax error on the code at the following line:

`cout<<endl<<<(2<<2);`

Which should be:

`cout<<endl<<(2<<2);`

Notice that the `<<<` just before `(2<<2)` causes a problem.
