Arrays

An array is an ordered collection of variables which are of the same type. Each variable in the array is called an element, and these elements can be accessed by the location (index) in the array. When an array is defined we must declare the type of variables that will be stored in it. There are several ways that an array can be defined. The following examples show some of the basic ways to define an array:

int myInts[10];
int myInts[] = {1, 2, 3, 4};
int myInts[8] = {2, 4, 6, 8, 10};

Each of these examples defines an array of integers. The first example defines an uninitialized array of ten integers. Be careful when defining uninitialized arrays because the memory locations are never initialized, which could lead to very unexpected results.

The second example defines an array of four integers were all of the elements are initialized with values. This array is automatically...
