Program Plan Intro

Array of structures:

In C++, it is possible to create an array of structure; it is used to store a group of records contains multiple data members of various data type. A single array of structure can replace many arrays of regular type variable.

• Array of structures can be defined like normal array.

The structure array is declared through the following format:

struct_name variable[size];

Consider the following array definition:

//Declaration of structure array

Car values[5];

• In the above example, “Car” represents the structure type of the array, “values[]” is the array name, and the number inside the brackets is the size declaratory of the array.

Subscript of an array:

In C++, array elements can be accessed using a subscript. In an array, each element assigned with the unique number, which is specified inside the brackets, is referred as a subscript.

• By default, structure members are defined as “public”. Hence structure members can be accessed by place the dot operator (.) and member name after the array subscript.

Example:

//Assign the value for model member of values[2].

values[2].model = "New"

• In above statement, the value “New” is assigned in the third element of the “values” array for model member.
