Chapter 7: Problem 51

To calculate the amount of memory used by an array, multiply the number of elements by the number of bytes each element uses.

Short Answer

Expert verified

Answer: To calculate the total memory used by an array, multiply the number of elements in the array by the number of bytes each element uses. This value depends on the data type of the elements in the array. For example, if the array has 10 integer elements, and each integer uses 4 bytes of memory, the total memory used by the array is 10 elements * 4 bytes/element = 40 bytes.

Step by step solution

Understanding the array and its elements

An array is a data structure that can store a fixed size of elements, and these elements must be of the same data type. The elements in the array are identified by an index. To calculate the amount of memory used by an array, we first need to know the number of elements in the array.

Knowing the number of bytes each element uses

In an array, all elements use the same amount of memory since they are of the same data type. Different data types use different amounts of memory (measured in bytes). Common data types and their memory usage are: a. int (4 bytes) b. float (4 bytes) c. double (8 bytes) d. char (1 byte)

Calculate the total memory used by the array

To calculate the total amount of memory used by the array, we multiply the number of elements in the array by the number of bytes each element uses. For example, let's consider an array of integers with 10 elements. Since each integer uses 4 bytes of memory, we can calculate the total memory used by the array as follows: Memory used by the array = (Number of elements) * (Bytes per element) Memory used by the array = (10 elements) * (4 bytes/element) Memory used by the array = 40 bytes Thus, the total memory used by the array in this example is 40 bytes.
