Structures

Structures with in structures

Structures within a structure means nesting of structures.

Example:

struct salary

{

char name [20];

char department [10];

int basic-pay;

int dearness-allowance;

int huse_rent_allowance;

int city_allowance;

}

employee;

This structure defines name, department, basic pay and three kinds of allowances.

All the items related to allowance can be grouped together and declared under a sub-stricture. As shown below, strut salary

{

char name []2;

char department [10];

struct;

}

int dearness;

int house_rent;

int city;

[allowance;

}

employee's;

The salary structure contains a member named allowance which use is a structures with.

Three members. Now ; the member compared in the inner structure;, namely, ;dearness, house_rent and city can ;be left to as;

employee. ;allowance. Dearness

employee. Allowance. House_rent

employee allowance. city

The inner most member in a nested structure can be accessed by chaining all the concerned structure variables (from outermost to inner most) with the member using dot operator.
