Objectives

In this chapter you’ll:

• Use C++ Standard Library class template array—a fixed-size collection of related data items.

• Use arrays to store, sort and search lists and tables of values.

• Declare arrays, initialize arrays and refer to the elements of arrays.

• Use the range-based for statement.

• Pass arrays to functions.

• Declare and manipulate multidimensional arrays.

• Use C++ Standard Library class template vector—a variable-size collection of related data items.
