♦ Arrays can be defined as a set of variables which contains values of same data types having same variable name but different
subscripts required to separate the values.
♦ Two or more elements arranged row-wise containing separate subscript values indicating the position of the element is known
as single dimensional array or 1D array.
♦ The total number of elements an array holds is the length of the array.
♦ Searching is used to determine whether an element is present in the array or not.
♦ Sorting is the process of arranging the elements either in the ascending or the descending order.
♦ Insertion is the process of adding an element at any desired position in the array.
♦ Deletion is the process of deleting or removing an element from the array from the given position.
♦ Merging is the process of combining two or more than two arrays.
