How do parallel arrays affect programming efficiency?

Answer 1

To understand this, you need to understand that an array is a simple data type, meaning that it can ONLY store ONE type of data within it, even though it can store multiple values.

An array is basically like a list, of the same items. You can have a two dimensional list as well, but they still MUST be the same type of item.

A parallel array comes in to play when you CANT use a two dimensional array to store values, like when you need to store related information that IS NOT the same data type. For example, I have a list of names of cars, and how many cars I have total, these are different datatypes so I cant make a two dimensional array with them, but they are still related, so I will make a parallel array.

Therefore it is an idea that would make things that are otherwise almost impossible, possible, and because hard coding values is time consuming and sucks.

Answer 2

Parallel is faster.

Answer 3

u mean jumper system, dont do that u just making mistakes the standard devices going burning the elements
