Chapter 7: Problem 32

When a two-dimensional array is passed to a function the _________ size must be specified.

Short Answer

Expert verified
Answer: The column size must be specified.

Step by step solution

01

Understand two-dimensional arrays

A two-dimensional array is an array of arrays, meaning it consists of rows and columns. This can be thought of as a matrix or a table of values. In programming, these arrays are utilized to store and manipulate data in a structured manner.
02

Passing two-dimensional arrays to functions

When we pass a two-dimensional array to a function, the function must know the size of the array in order to access and process the elements correctly. In C (and related languages), we can pass two-dimensional arrays to functions by specifying the array and its size parameters as arguments.
03

Specify the needed size

When passing a two-dimensional array to a function, there is one essential size that must be specified: the column size. This is because the memory layout of the array is stored in a row-major order (consecutively in memory). Specifying the column size allows the function to navigate through the array's elements correctly. Summary: When a two-dimensional array is passed to a function, the __column__ size must be specified.
