Question

The S of the famous Object Oriented Programming design stands for:

Single responsibility principle, the notion that an object should have
only a single responsibility.

I was wondering, can this principle, be extended even to arrays, variables, and all the elements of a program?

For example, let’s say we have:

int A[100];

And we use it to store the result of a function, but somehow we use the same A[100] to check, for example, what indexes of A have we already checked and elaborated.
Could this be considered wrong? Shouldn’t we create another element to store, for example, the indexes that we have already checked? Isn’t this an hint of future messy code?

PS: I’m sorry if my question is not comprehensible but English is not my primary language. If you have any problem understanding the point of it please let me know in a comment below.

Answer 1

If same A instance is used in different program code portions you must follow this principle. If A is a auxiliary variable, local one for example, I think you don’t need to be care about it.
