Importance of removing Dead codes

Importance of removing Dead codes

I went through the old project that I created when I started my coding journey and discovered a lot of dead code. I did some research and came across the Dead-code elimination theory (DCE).

DCE is a compiler optimization that removes code that has no effect on the program's output.

Removing such code has several benefits:
it shrinks program size, an important consideration in some contexts, and it allows the running program to avoid executing irrelevant operations, which reduces its running time.
It can also enable further optimizations by simplifying program structure.


The following pictures illustrate how you can remove dead codes using visual studio code
