Consider the following union declaration: 1 union ele struct long *p; long y; e1 struct long x; union ele *next; e2 10 This declaration illustrates that structures can be embedded within unions. The following procedure (with some expressions omitted) operates on a linked list having these unions as list elements: void proc (union ele up) up A. What are the offsets (in bytes) of the following fields: e1.p el.y e2.x e2.next B. How many total bytes would the structure require? C. The compiler generates the following assembly code for the body of proc
