The document discusses structures in C programming. It defines structures as a way to group individual elements of different types together under a single name. Structures allow defining custom data types that can contain integers, floats, chars, arrays, pointers, and other structures. The key points covered include defining structures, initializing structure members, nested structures, arrays of structures, pointers to structures, and passing structures to functions.

10. 7.2 Defining a Structure – cont’5

21. 7.5 Initializing Structures – cont’1 struct date { int month; int day; int year; }; struct custAccount { int accNo; char accType; char name[80]; float accBalance; struct date payment; }; static struct custAccount cust= {2345,‘S’,“Khadijah Ismail”,2400.90,9,7,2006}; : Example 7.9

22. 7.5 Initializing Structures – cont’2 Example 7.10:

24. 7.6 Nested Structures – cont’1 struct employees{ char empName[25]; char address[30] ; char city [10] ; char state[2] ; long int poscode ; double salary; }; struct customers{ char custName[25]; char address[30] ; char city [10] ; char state[2] ; long int poscode ; double balance; }; struct addressInfo{ char address[30]; char city [10]; char state[2]; long int poscode; }; struct employees{ char empName[25]; struct addressInfo eAddress; double salary; }e1; struct customers{ char custName[25]; struct addressInfo cAddress; double balance; }c1; Example 7.12: :Example 7.13
