Chapter 8: Problem 17

To define a two-dimensional array, _________ size declarators are required.

Short Answer

Expert verified
Answer: Two size declarators are required.

Step by step solution

01

Identify a Two-Dimensional Array

A two-dimensional array, also known as a matrix, is essentially an array of arrays. In terms of programming, it can be thought of as a table with rows and columns, where data is stored in each cell.
02

Understand Size Declarators

Size declarators are used to define the dimensions of an array. They specify how many rows and columns the array should have, in the case of a two-dimensional array.
03

Find the Number of Size Declarators Needed

To define a two-dimensional array, you need to specify the number of rows and the number of columns. Since you need one size declarator for the number of rows and another for the number of columns, the answer is two size declarators are required.
