Unlocking the Power of C++ Structures: A Step-by-Step Guide

Laying the Foundation

To harness the full potential of C++ structures, it’s essential to have a solid grasp of fundamental concepts, including C++ structures, strings, and data manipulation.

Crafting a Custom Structure

Let’s create a structure called “student” that comprises three vital data members: name, roll, and marks. This structure will serve as a blueprint for storing and displaying information.

struct student {
    string name;
    int roll;
    float marks;
};

Bringing the Structure to Life

Next, we’ll create a structure variable “s” to store data entered by the user. This variable will hold the values for name, roll, and marks, which will be input by the user.

student s;

User Input and Data Storage

The program prompts the user to enter their name, roll, and marks. This data is then stored in the corresponding data members of the structure variable “s”. This seamless integration of user input and data storage enables efficient information management.

cout << "Enter your name: ";
getline(cin, s.name);

cout << "Enter your roll number: ";
cin >> s.roll;

cout << "Enter your marks: ";
cin >> s.marks;

Displaying the Results

Finally, the program displays the data entered by the user, showcasing the stored information in a clear and concise manner. This output demonstrates the effectiveness of using structures to organize and present data.

cout << "Name: " << s.name << endl;
cout << "Roll Number: " << s.roll << endl;
cout << "Marks: " << s.marks << endl;

A Closer Look at the Example

In this program, the “student” structure is designed to hold three essential pieces of information: name (string), roll (integer), and marks (float). The structure variable “s” is then used to store and display this data, providing a comprehensive view of the user’s input.

• Name: a string to store the user’s name
• Roll: an integer to store the user’s roll number
• Marks: a float to store the user’s marks

By mastering the art of creating and utilizing C++ structures, you’ll unlock a world of possibilities for efficient data management and presentation.
