Custom Types

C++ Structures

Structures (struct) allow you to group variables of different data types under a single name. They represent a "record" or "entity".

DEFINITION & USAGE

struct Student {
    string name;
    int age;
    double gpa;
};

Student s1 = {"Alice", 20, 3.8};
cout << s1.name; // Access with dot (.)

HETEROGENEOUS

Unlike arrays, members can be of different types.

PUBLIC BY DEFAULT

All members of a struct are public unless specified otherwise.

DSA USE CASE

Used to build complex nodes in data structures like Linked Lists (struct Node) or Trees.

struct Node { int data; Node* next; };
