Chapter 7: Problem 3

What would the valid subscript values be in a four-clement array of doubles?

Short Answer

Expert verified
Answer: The valid subscript values for a four-element array of doubles are 0, 1, 2, and 3.

Step by step solution

01

Array Size and Indexing

The given problem states that we have a four-element array of doubles. In most programming languages, the index of an array starts at 0. So, for this four-element array, the index positions will begin at 0 and increase by 1 for each new element.
02

Valid Subscript Values

Since we have a four-element array and start indexing at 0, the valid subscript values for this array will be: \\(0, 1, 2,\\) and \\(3\\). These integer values represent the index positions for each element in a four-element array of doubles.
