Structures in C++

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	Structures in C++ programming में Struct use होता है।
member	Structures in C++ programming में Member use होता है।
record	Structures in C++ programming में Record use होता है।
dot operator	Structures in C++ programming में Dot operator use होता है।
data grouping	Structures in C++ programming में Data grouping use होता है।

Syntax / Pattern

C++

struct Name { data members; };

Example Program

main.cpp

#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++ एक ज़रूरी C++ topic है। परिभाषा सीखें, syntax समझें, example program चलाएं और फिर practice tasks हल करके concept मज़बूत करें।
