What is Structures in C++?

Structures in C++
A structure groups different data types under one name. It is useful for representing records such as student, book or employee.

🔵 Core C++ Features

Example File
structures.cpp

Main Focus
Concept + syntax + practical C++ program

Why should you learn this?

It helps you write correct and readable C++ programs.
It is used repeatedly in school practicals, projects and competitive programming.
It builds the base for advanced topics such as OOP, STL and data structures.

Important Terms

Term	Meaning / Use
struct	Struct used in Structures in C++ programming.
member	Member used in Structures in C++ programming.
record	Record used in Structures in C++ programming.
dot operator	Dot operator used in Structures in C++ programming.
data grouping	Data grouping used in Structures in C++ programming.

Syntax / Pattern

struct Name { data members; };

Example Program

#include <iostream>
using namespace std;
struct Student{
    int roll;
    string name;
};
int main(){
    Student s{1, "Aman"};
    cout << s.roll << " " << s.name;
    return 0;
}

Expected Output

1 Aman

Program Explanation

Student groups roll and name.
s.roll accesses the roll member.

Exam Tip: In C++ practical answers, write the logic first, then the program, then expected output. For theory, always include one suitable example.

Where will you use it?

student record
employee record
library book record

Common Mistakes

Forgetting semicolon after struct definition.
Confusing struct and object.

Practice Tasks

Create Book structure.
Store three students using array of structures.

Summary

Structures in C++ is an important C++ topic. Learn the definition, understand the syntax, run the example program and then solve the practice tasks to make the concept strong.
