The following
arithmetic based on values typed at the keyboard. It outputs a single
result.
1. Get W from the keyboard
2. X⋅W+W
3. Y⋅X+X
4. Z⋅Y+Y
5. Print Z to the screen
a. An interpreter would execute the program statement by statement.
In total, five statements would execute. If the underlying ISA were
capable of all arithmetic operations (i.e., addition, subtraction,
multiplication, division), at least how many operations would be
needed to carry out this program? State what the operations
would be.
b. A compiler would analyze the entire program before generating
machine code, and it would possibly optimize the code. If the
underlying ISA were capable of all arithmetic operations (i.e.,
addition, subtraction, multiplication, division), at least how many
operations would be needed to carry out this program? State what
the operations would be.
