1. How many bytes are allocated in total for the variables (va, vb, ve, vd, and ve)? 2. For each of the instructions highlighted (boldface), derive the effective address of the memory variable (source) if any memory variable is involved, and the contents of the register a ord (whichever one involved) right after the instruction is executed. Answer in hexadecimal. Assume that all of the bytes in the variables va, vb and vc are initially 0.
