What efficiency is gained by passing data to an array?

The array efficiency is the fastest array accessing process when the contiguous accessing array occur in the system.

We can pass data into an array by using the pass by reference concept and it can perform one and more array operation so that it can easily access all the main parts of an array.

When the system only allow the assume shape array concept and do not use ant type of temporary array in the system then, high efficiency are gain by passing data in an array concept.
