Questions & Step-by-Step Solutions
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.
