Declaring and initializing a string

There are several ways to declare and initialize a string. We will explore the various ways to both declare and initialize strings in this section.

String declarations

We can declare a string in several ways. The first way is to declare a character array with a specified size, as follows:

char aString[8];

This creates an array of 8 elements, capable of holding seven characters (don't forget the terminating NUL character).

The next way to declare a string is similar to the first method but instead, we don't specify the size of the array, as follows:

char anotherString[];

This method is not useful unless we initialize anotherString, which we will see in the next section. As you may recall from Chapter 14, Understanding Arrays and Pointers, this declaration looks like a pointer in the form of an array declaration. In fact, without initialization, it is.
