Example: Basic Student Structure Processing in C++

// Basic Student Structure Processing
#include <iostream> // For input/output operations
#include <string>   // For using std::string
#include <vector>   // For using std::vector (dynamic array)

// Define the Student structure
struct Student {
    int id;
    std::string name;
    double score;
};

int main() {
    // Step 1: Declare a vector of Student objects
    // Using std::vector for dynamic sizing, more flexible than raw arrays.
    std::vector<Student> students;

    // Step 2: Populate student records
    // Let's add 3 student records for demonstration
    Student s1 = {101, "Alice", 85.5};
    Student s2 = {102, "Bob", 78.0};
    Student s3 = {103, "Charlie", 92.3};

    students.push_back(s1);
    students.push_back(s2);
    students.push_back(s3);

    // Step 3: Display student records
    std::cout << "Student Records:" << std::endl;
    for (const Student& s : students) { // Range-based for loop for easy iteration
        std::cout << "ID: " << s.id
                  << ", Name: " << s.name
                  << ", Score: " << s.score
                  << std::endl;
    }

    return 0;
