Questions & Step-by-Step Solutions
What is the purpose of constant folding in code optimization?
Steps
Concepts
Step 1: Understand that constant folding is a technique used in programming.
Step 2: Know that it happens during the compilation of code, not while the program is running.
Step 3: Identify that constant folding looks for expressions in the code that have constant values (like 2 + 3).
Step 4: Realize that instead of keeping the expression (2 + 3), the compiler replaces it with the result (5).
Step 5: Understand that this replacement reduces the amount of work the program has to do while it runs.
Step 6: Conclude that the main purpose of constant folding is to make programs run faster by simplifying calculations before they happen.
