C++ Structures (struct)

A structure in C++ is a user-defined data type that groups related data together. It allows you to create a composite data type by combining different types of data into a single unit.

Step 1: Defining a Structure To define a structure, you use the struct keyword followed by the name of the structure and a set of curly braces. Inside the curly braces, you declare the members of the structure, which can be of any data type, including other structures.

Step 2: Accessing Structure Members You can access the members of a structure using the dot (.) operator. This allows you to read or modify the values of the structure's members.

Step 3: Example Here's an example of defining and using a simple structure in C++:

// Define a structure
struct Person {
    string name;
    int age;
    double height;
};

// Create an instance of the structure
Person person1;

// Access and modify structure members
person1.name = "John";
person1.age = 25;
person1.height = 6.2;

Step 4: Using Structures You can use structures to create complex data types that represent real-world entities, such as employees, students, or any other object with multiple attributes.

Step 5: Passing Structures to Functions Structures can be passed as arguments to functions, allowing you to operate on complex data types within your program.

Step 6: Conclusion Structures in C++ provide a way to organize and manipulate related data in a convenient and efficient manner. They are a fundamental part of C++ programming and are widely used in various applications.
