Question 1.
What is an accumulator?
Show hintHide hint
Think of a temporary storage area during computations.
Question 2.
Name one advantage of zero-address instructions.
Show hintHide hint
Consider how operations can call upon stored values.
3Question 3.
What is the purpose of the accumulator?
- To permanently store data
- To hold intermediate operation results
- To control user inputs
Show hintHide hint
Remember it as the workspace in programming.
4Question 4.
True or False: Zero-address instructions require explicit memory addresses for each operation.
- True
- False
Show hintHide hint
Focus on how data is accessed in zero-address formats.
Question 5.
You need to calculate (A + B) * (C + D) using both single-address and zero-address instructions. Analyze the instruction count for each.
Show hintHide hint
Compare the number of push and pop operations in zero-address against individual loading and storing in single-address.
Question 6.
Discuss how using a single operand as both source and destination simplifies coding. Provide an example through pseudo-code.
Show hintHide hint
Think about how many operations are avoided with direct assignment versus using additional variables.
