Five values of type int can be declared as an array without having to declare five different variables (each with its own identifier).
What does the number 6 mean in the array declaration?
The number 6 in the array declaration indicates the last index in the array; it is one less than the number of elements in the array. It assigns values to each element in the array. Array elements are accessed by using the array name and including the index of the individual element in parentheses. It lists each value of the array.
What are the major parts of an array?
Summary: An array is a data structure for storing multiple data items that have a similar data type. Identifier, data type, array length, elements, and index are the major parts of an array. Use the index for processing the values of array elements. Arrays have excellent support for keeping data-type intact.
