1️⃣ Introduction to Structure in C
What is a Structure?
A structure is a user-defined data type in C that allows us to group different types of data members under a single name.
In simple words, a structure helps us store related information of different data types together.
Example:
Suppose we want to store the details of a student:
Student Name
Roll Number
Marks
Age
We can use a structure to store all these details together.
Important Points
Structure is a user-defined data type.
It can store different types of data.
It groups related information together.
Each member has its own name and data type.
2️⃣ Why Do We Use Structure in C?
Structures are used when we need to store multiple related values of different data types in one place.
Example:
For a student record:
Name – char array
Roll Number – int
Marks – float
Age – int
Using a structure, we can manage all these details under one structure variable.
3️⃣ Structure Declaration in C
What is Structure Declaration?
Structure declaration means defining a structure type and specifying its members.
Syntax:
struct structure_name
{
data_type member1;
data_type member2;
data_type member3;
};
Example:
struct Student
{
char name[50];
int roll;
float marks;
};
Here:
struct is the keyword.
Student is the structure name.
name, roll and marks are structure members.
4️⃣ Structure Variables in C
What is a Structure Variable?
A structure variable is used to store actual data in the members of a structure.
Example:
struct Student s1;
Here, s1 is the structure variable of the Student structure.
5️⃣ Structure Initialization in C
What is Structure Initialization?
Structure initialization means assigning initial values to structure members when declaring a structure variable.
Example:
struct Student s1 = {"Rahul", 101, 85.5};
Here:
Rahul is the student's name.
101 is the roll number.
85.5 is the marks.
6️⃣ Accessing Structure Members in C
We use the dot (.) operator to access individual members of a structure.
Syntax:
structure_variable.member_name;
Example:
s1.roll = 101;
s1.marks = 85.5;
Here, the dot operator accesses the roll and marks members of the structure variable s1.

Each member has its own name and data type.

struct structure_name
{
data_type member1;
data_type member2;
data_type member3;
};
Example:

{
char name[50];
int roll;
float marks;
};
Here:
struct is the keyword.
Student is the structure name.
name, roll and marks are structure members.
4️⃣ Structure Variables in C

A structure variable is used to store actual data in the members of a structure.
Example:
struct Student s1;
Here, s1 is the structure variable of the Student structure.
5️⃣ Structure Initialization in C
What is Structure Initialization?
Structure initialization means assigning initial values to structure members when declaring a structure variable.
Example:
struct Student s1 = {"Rahul", 101, 85.5};
Here:
Rahul is the student's name.
101 is the roll number.
85.5 is the marks.
6️⃣ Accessing Structure Members in C
We use the dot (.) operator to access individual members of a structure.
Syntax:
structure_variable.member_name;
Example:
s1.roll = 101;
s1.marks = 85.5;
Here, the dot operator accesses the roll and marks members of the structure variable s1.
