How do you deal with shift in cpp?

Question

let's assume this sample code... jump to the point...

int x= 5;
//using a shift right or left...
//is it
cout << <<x;

//or

x=<<x;
cout<<x;

Answer 1

When bitshifting, you always have to specify by how much you want to shift.

cout << (x << 1);

Shifts left by 1 bit and prints the result.
