Structures within a structure means nesting of structures.

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;

employee. ;allowance. Dearness
employee. Allowance. House_rent
employee allowance. city
