Code optimization in compiler design javatpoint

Why is optimization important in programming?
In general, a computer program may be optimized so that it executes more rapidly, or to make it capable of operating with less memory storage or other resources, or draw less power..
Solution: Benefits of code optimization technique:
Cleaner Code Base.Higher Consistency.Faster Sites.Better Code Readability.More Efficient Refactoring.More Straightforward Debugging.Improved Workflow.Easier Code Maintenance.
Ans.
The principal sources of optimization in computer science and IT engineering are code optimization, algorithm optimization, system optimization, network optimization, and data optimization.
These sources help in improving the performance, scalability, and reliability of software systems.
Code optimization is a program modification strategy that endeavours to enhance the intermediate code, so a program utilises the least potential memory, minimises its CPU time and offers high speed.
In computing, an optimizing compiler is a compiler that tries to minimize or maximize some attributes of an executable computer program.
Common requirements are to minimize a program's execution time, memory footprint, storage size, and power consumption (the last three being popular for portable computers).

Machine independent optimization attempts to improve the intermediate code to get a better target code. The part of the code which is transformed here does

The process of intermediate code generation introduces much inefficiency like: using variable instead of constants, extra copies of variable, repeated evaluation of expression. Through the code optimization, you can remove such efficiencies and improves code.
