1. Use the virtual machine codes (format shown below) to describe the operational semantics of the following C++ statements.

Virtual machine code format: (id here refers to any identifier/variable.)

id1 = id2

id = id1 op id2 (here op could be any arithmetic or logical operator.)

goto label

if id1 relop id2 goto label (here relop could be any relational operator)

total = 0;

for (int i=0; i

total = ++total + i * i

}
