One Dimensional Array

 A list of items can be given one variable name using one subscript and such a variable is called a single-subscripted variable or a one-dimensional array. For example, suppose if we want to represent a set of numbers, say (20, 10, 24, 26, 34), by array variable number, then we may declare the variable number as follows

                                int number[5];

and the computer reserves five storage locations as shown below:

The values to the array element can be assigned as follows

                                                number[0]=20;

                                                number[1]=10;

                                                number[2]=24;

                                                number[3]=26;

                                                number[4]=34;
