By leveraging the class mechanism in C++, we can organize data and related operations in a structured manner, making our code more modular and maintainable.

C++ Program to Read and Display Student Details using Class

Creating the Student Class

To begin with, let’s define a class named “Student” that will encapsulate the information related to a student’s details.

Here’s an example of how we can define the class:

class Student {
private:
    std::string name;
    int rollNumber;
    int age;

public:
    void readDetails();
    void displayDetails();
};

In the above code snippet, we have declared three private member variables: name, rollNumber, and age.

These variables will store the student’s name, roll number, and age, respectively. We have also defined two member functions, readDetails() and displayDetails(), which will be used to input the student’s details and display them on the screen.

Implementing the Member Functions

Let’s now implement the member functions of the Student class.

The readDetails() Function

The readDetails() function allows the user to input the student’s details. Here’s an example implementation:

void Student::readDetails() {
    std::cout << "Enter name: ";
    std::cin >> name;

    std::cout << "Enter roll number: ";
    std::cin >> rollNumber;

    std::cout << "Enter age: ";
    std::cin >> age;
}

In the above code, we use std::cout to display prompts for input, and std::cin to read the values entered by the user into the respective member variables of the Student object.

The displayDetails() Function

The displayDetails() function is responsible for displaying the student’s details. Here’s an example implementation:

void Student::displayDetails() {
    std::cout << "Name: " << name << std::endl;
    std::cout << "Roll Number: " << rollNumber << std::endl;
    std::cout << "Age: " << age << std::endl;
}

In the above code, we use std::cout to display the student’s name, roll number, and age on the console.

Using the Student Class in the Main Program

Now that we have defined the Student class and its member functions, let’s see how we can utilize them in our main program to read and display student details.

int main() {
    Student student;

    // Read student details
    student.readDetails();

    // Display student details
    std::cout << "Student Details:" << std::endl;
    student.displayDetails();

    return 0;
}

In the above code, we create an object of the Student class named student. We then call the readDetails() function to input the student’s details and the displayDetails() function to display them on the console.

Conclusion

In this article, we have explored a C++ program that allows us to read and display student details using the concept of classes.

By using classes, we can organize the student’s information in a structured manner and perform operations on it more efficiently. C++ provides a powerful object-oriented programming paradigm, making it an excellent choice for building robust and scalable software applications.

Remember to practice and experiment with the code to deepen your understanding of C++ programming and its concepts. Happy coding!
