What is a structure in C++?

The structure is defined as a collection of different data type elements under a common name. It is similar to a class as the class and structure can hold elements of different types.

How to declare a structure in C++ programming?

The struct keyword defines a structure followed by an identifier. Then we can add the structure members using curly braces. For example:


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

In this example, we have made a structure with the name 'people' and have the members as 'name', 'age', 'salary'

How to create a C++ Program to Store Information of a Student in a Structure?

Here we are creating a structure called student and name, roll and marks as its data members. Then create a structure variable s. Ask the user to enter the details of the student data like name, roll, and marks. Store these data taken from the user in data members of s. Finally, display the data entered by the user on the screen.

 

Algorithm

Step 1:  Call the header file iostream.

Step 2: Use the namespace std.

Step 3:  Create a structure student

Step 4: Create data members, name, roll, and marks

Step 5: Open the integer type main function; int main().

Step 6: Create a structure variable s

Step 7: prompt the user to enter the data of the student.

Step 8: Store the entered details in the data members.

Step 9: Display the details on the screen

Step 10: Exit

C++ Source Code

                                          #include <iostream>
using namespace std;

struct student
{
    char name[50];
    int roll;
    float marks;
};

int main() 
{
    student s;
    cout << "Enter information," << endl;
    cout << "Enter name: ";
    cin >> s.name;
    cout << "Enter roll number: ";
    cin >> s.roll;
    cout << "Enter marks: ";
    cin >> s.marks;

    cout << "\nDisplaying Information," << endl;
    cout << "Name: " << s.name << endl;
    cout << "Roll: " << s.roll << endl;
    cout << "Marks: " << s.marks << endl;
    return 0;
}
                                      

OUTPUT

Enter information,
Enter name: John
Enter roll number: 007
Enter marks: 99%
Displaying Information,
Name: Shyn
Roll: 7
Marks: 99
