Aspects of writing efficient
In present time the cost of hardware has reduced significantly and now a normal person can easily afford personal computers with standard hardware.
- Even though there has been downfall in the cost of hardware, but there is more effort to produce efficient and quality code.
- One reason is the execution time. Some programs like system software need to run continuously for long hours.
- So, they need to be efficient enough to meet the needs of the users. Also some may argue that instead of wasting efforts to optimize code, one can always upgrade his hardware.
- But who would want to upgrade the hardware for running just one code...

How often does a good compiler write better code than an assembly language programmer on modern machines? So what if we try?
Uses a compiler to turn high-level code into machine language. The compiler has an effect on CPU speed. If that's the case, then what? If that's the case, then how is it possible? Explain why you came to that conclusion.
Is there ever a time when it makes sense to use assembly language rather than compiled code when developing software for a specific purpose?
