ARRAY NOTATION

An array is a collection of identical data object which are stored in consecutive memory locations under a common heading or a variable name. In other words, an array is a group or a table of values referred to by the same variable name. The individual values in an array are called elements. Array elements are also variables.

    Arrays are sets of values of the same type, which have a single name followed by an index. In C++, square brackets appear around the index right after the name, with the first element referred to by the number.

    Whenever an array name with an index appears in an expression, the C++ compiler assumes that element to be of an array type.
