What are the different types of structures in C programming?

In C programming, structures are user-defined data types that group related variables. The main types include:

1. Simple Structures: Basic structures that hold different data types.
2. Nested Structures: Structures within structures.
3. Array of Structures: An array where each element is a structure.
4. Structure Pointer: A pointer that points to a structure.

Can you give me an example of a simple structure?

Sure! Here's a simple structure example:

struct Student {
    char name[50];
    int age;
    float gpa;
};

This structure defines a student with a name, age, and GPA.

How do I access the members of a structure?

You can access the members of a structure using the dot operator. For example:

struct Student s1;
s1.age = 20;
s1.gpa = 3.5;

This sets the age and GPA for the student.

What is a nested structure?

A nested structure is a structure that contains another structure as a member. For example:

struct Address {
    char city[50];
    char state[50];
};

struct Student {
    char name[50];
    struct Address addr;
};

Here, the Student structure contains an Address structure.
