C – Array of Structures

Prev Next

As you know, C Structure is collection of different datatypes ( variables ) which are grouped together. Whereas, array of structures is nothing but collection of structures. This is also called as structure array in C.

Example program for array of structures in C:

This program is used to store and access “id, name and percentage” for 3 students. Structure array is used in this program to store and display records for many students. You can store “n” number of students record by declaring structure variable as ‘struct student record[n]“, where n can be 1000 or 5000 etc.


Records of STUDENT : 1
Id is: 1
Name is: Raju
Percentage is: 86.500000
Records of STUDENT : 2
Id is: 2
Name is: Surendren
Percentage is: 90.500000
Records of STUDENT : 3
Id is: 3
Name is: Thiyagu
Percentage is: 81.500000

Example program for declaring many structure variable in C:

In this program, two structure variables “record1″ and “record2″ are declared for same structure and different values are assigned for both structure variables. Separate memory is allocated for both structure variables to store the data.


Records of STUDENT1:
Id is: 1
Name is: Raju
Percentage is: 90.500000
Records of STUDENT2:
Id is: 2
Name is: Mani
Percentage is: 93.500000
