Question: Which optimization technique focuses on reducing the number of instructions executed?

Options:

Correct Answer: Constant folding

Solution:

Constant folding focuses on reducing the number of instructions executed by evaluating constant expressions at compile time.

Which optimization technique focuses on reducing the number of instructions executed?

Which optimization technique focuses on reducing the number of instructions executed?

Step 1: Understand that optimization techniques are methods used to improve the performance of a program.
Step 2: Identify that one goal of optimization is to reduce the number of instructions a program executes.
Step 3: Learn about constant folding, which is a specific optimization technique.
Step 4: Recognize that constant folding evaluates constant expressions (like 2 + 3) during the compilation of the program instead of during execution.
Step 5: Conclude that by evaluating these expressions early, constant folding reduces the total number of instructions that need to be executed when the program runs.
