In C++ Structure is a collection of variables of different data types under a single name. It is similar to a class in that, both holds a collecion of data of different data types. For example: You want to store some information about a person: his/her name, citizenship number and salary.

Structure is a constructed building or a specific arrangement of things or people, especially things that have multiple parts. An example of structure is a newly built home. An example of structure is the arrangement of DNA elements. In C++, a structure is a user-defined data type. The structure creates a data type for grouping items of different data types under a single data type. For example: Suppose you need to store information about someone, their name, citizenship, and age.

A STRUCT is a C++ data structure that can be used to store together elements of different data types. In C++, a structure is a user-defined data type. The structure creates a data type for grouping items of different data types under a single data type. It means variables for different individuals will be created.

examples:

#include <iostream>
using namespace std;

struct Person
{
    char name[50];
    int age;
    float salary;
};

int main()
{
    Person p1;
    
    cout << "Enter Full name: ";
    cin.get(p1.name, 50);
    cout << "Enter age: ";
    cin >> p1.age;
    cout << "Enter salary: ";
    cin >> p1.salary;

    cout << "\nDisplaying Information:" << endl;
    cout << "Name: " << p1.name << endl;
    cout <<"Age: " << p1.age << endl;
    cout << "Salary: " << p1.salary;

    return 0;
}

output

Enter Full name: your name
Enter age: 12
Enter salary: 100000.0

Displaying Information:
Name: your name
Age: 12
Salary: 100000.0
