What is a good analogy for explaining the actions of a compiler?
kozerog [31]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

This question is about what is a good analogy for explaining the actions of a compiler?  The correct option is <u> automatic programming of kitchen devices .</u>

<u> </u>

a hybrid ability of a car to use multiple energy sources  (false)

this analogy is not correctly mapped on the compiler, becuase the compiler can be designed only for one type of language, for example, the program that calculates the average of students number can be easily programmed in C++ and in C#. But you cannot compile the C# program in C++ compiler and vice versa.  

a street map of a local subdivision  (false)

Because you can design a compiler for a not specific subdivision of programming.

an interpreter who speaks several languages

it is not an analogy, however, an interpreter can handle only one type of language.

an automatic programming of kitchen devices (true)

This is a good analogy of compiler because you give input to the device and that device based on your input gives you back an output. Similarly, you give input to the compiler in form of language syntax, and it automatically give you output based on your input.
