Given the parametric equation of line $l$ as $\begin{cases} x=1+\frac{\sqrt{2}}{2}t \\ y=\frac{\sqrt{2}}{2}t \end{cases}$ ($t$ is the parameter), a polar coordinate system is established with the coordinate origin as the pole and the positive semi-axis of $x$ as the polar axis. The polar coordinate equation of circle $C$ is $\rho =4\cos \theta$, and line $l$ intersects with circle $C$ at points $A$ and $B$.

(1) Find the rectangular coordinate equation of circle $C$ and the general equation of line $l$.

(2) Given point $P(1,0)$, find the value of $| |PA|-|PB| |$.
