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.

FAQs (Frequently Asked Questions)
A: The purpose of using classes in this program is to encapsulate the student’s details and related operations into a single entity, making the code more organized, modular, and reusable.
Student
class? A: Yes, you can add more member variables to the Student
class based on the additional information you want to store for each student. Just make sure to update the readDetails()
and displayDetails()
functions accordingly.
A: To handle multiple students’ details, you can create an array or vector of Student
objects and use loops to read and display the details for each student.
A: Yes, you can add validation checks in the readDetails()
function to ensure that the age entered by the user is within a certain range or meets specific criteria.
Student
class in other C++ programs? A: Yes, once you have defined the Student
class, you can use it in other C++ programs by including the class declaration and implementation in the respective source files.
A: Yes, there are many resources available for learning C++ programming. Some recommended sources include online tutorials, books, and documentation such as the C++ reference on cppreference.com.
