a) Consider the following JavaScript program: var a, y, C; function subl() { var b, z, c; } function sub2 () { var a, b, y; } function sub3 () { var a, x, W; } List all the variables, along with the program units where they are declared, that are visible in the bodies of sub2 when the sequence of function call is: "sub1 calls sub3 and sub3 calls sub2", assuming dynamic scoping is used.

To ensure that a reading has been captured, the gates only open when a valid registration is read. Exit gates also have a camera which scans the car registration number and will open automatically unless payments are outstanding in which case the payment can be made at the attendant kiosk without leaving the car. Members whose membership has expired can also pay for the…
