Write a definition statement for a character array named city. It should be large enough to hold a string 30 characters in length.

Short Answer

Expert verified
Question: Write a definition statement for a character array named 'city' capable of holding a string with a length of 30 characters. Answer: In C or C++, you would write `char city[31];` and in Java, you would write `char[] city = new char[31];` to define a character array named 'city' capable of holding a string of 30 characters.

Step by step solution

01

Choosing the Correct Data Type

To store an array of characters, we need to use the char data type. Char is used for storing single characters, but when combined into an array, it can hold strings.
02

Define the Size of the Array

We want our character array to be able to hold a string of 30 characters in length, so we need to set the size of the array accordingly. However, since in most programming languages strings end with a null terminator, we need to add an extra space for this, making the size of the array 31.
03

Write the Definition Statement

By combining the data type and the size of the array, we can now write the definition statement for the character array named 'city'. In C or C++: ```c char city[31]; ``` In Java (using an array of char): ```java char[] city = new char[31]; ```
