Arrays :

Arrays is a data structure, which provides the facility to store a collection of data of same type under single variable name. Just like the ordinary variable, the array should also be declared properly. The declaration of array includes the type of array that is the type of value we are going to store in it, the array name and maximum number of elements.

The type may be any valid type supported by C. Array names, like other variable names, can contain only letter, digit and underscore characters. Array names cannot begin with a digit character. I.e., The rule for giving the array name is same as the ordinary variable. The size should be an individual constant. To refer to a particular location or element in the array, we specify the name of the array and the index of the particular element in the array. The index specifies the location of the element in the array. The array index starts from zero. The maximum index value will be equal to the size of the array minus one. The array index can be an integer variable for an integer constant.
