Using ArraysAn array is a collection of more than one element of the same datatype. For
example, an array of characters would be of the data type char, and an array of
integers would be of the data type int. The number of elements in an array is
determined by the size of the array.
To declare an array in programming, we use a specific syntax. In C language, for
example, we would write:
int n;
to declare an integer variable. To declare an array, we would use:
int a[16];
This creates an array called "a" with 16 elements.
Initializing Arrays
Arrays can also be initialized with values. For example, we could initialize an
array of integers with the values 1, 2, and 3 like this:
int a[3] = {1, 2, 3};
Representing Arrays in Memory
To represent an array in memory, we need to know how the elements of the
array are stored. In a one-dimensional array, the elements are stored in a single
row with multiple columns.
Each element of the array takes up space in memory, depending on its data type.
For example, an array of integers would take up 2-4 bytes of memory per
element.
Overall, understanding memory and arrays is crucial to programming, as they
are fundamental building blocks of many programs and applications.
