ask $2$: Display Users

$//$ Display all users: $//$ This function takes as input: $//1)$ the users list $//$ And works as follows: $//1)$ Traverse the list, and invoke the GIVEN function $//$ print$\_$user$\_$data$($User $*$user$)$ to print the data of each user $//**$ DISCLAIMER$**$: You MUST not modify any GIVEN function or the contents of given cout's. void display$\_$users$($User $*$user$\_$head$)\{//$ TODO: Write code to implement $//$ Print this first and return imidiately if there are no users cout$<<"$No users in the system yet"$<<"$

$"$;$//$display this when no users exist cout $<<"===$ Users List $([$uid$,$ name$])==="<<$ endl; $\}$

Here is a sample way to display users:

Suppose we have John$($uid:$32),$ Bob$($uid:$6),$ and Peter$($uid:$56)$ in the list

$===$ Users List $([$uid$,$ name$])===$ User Id: $6,$ name: Bob User Id: $32,$ name: John User Id: $56,$ name: Peter
