Arrays in C Programming part 11 a

Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.
               Declaring individual variables, such as number0, number1, ..., and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and ..., numbers[99] to represent individual variables. A specific element in an array is accessed by an index.
All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.

Declare an array

Declare an array in C, a programmer specifies the type of the elements and the number of elements required by an array
 This is called a single-dimensional array. The arraySize must be an integer constant greater than zero and type can be any valid C data type. For example, to declare a 10-element array called balance of type double

Initialize an array

Initialize an array in C either one by one or using a single statement
 The number of values between braces { } cannot be larger than the number of elements that we declare for the array between square brackets [ ].

Accessed by indexing

Accessed by indexing the array name. This is done by placing the index of the element within square brackets after the name of the array.
