Example: Array of Student Structures in C

// Array of Student Structures
#include <stdio.h>
#include <string.h> // For strcpy

#define MAX_STUDENTS 3

int main() {
    // Step 1: Define the Student structure
    struct Student {
        int studentID;
        char name[50];
        float gpa;
    };

    // Step 2: Declare an array of Student structures
    struct Student students[MAX_STUDENTS];

    // Step 3: Initialize the student records
    // Student 1
    students[0].studentID = 101;
    strcpy(students[0].name, "Alice Green");
    students[0].gpa = 3.75;

    // Student 2
    students[1].studentID = 102;
    strcpy(students[1].name, "Bob Johnson");
    students[1].gpa = 3.20;

    // Student 3 (using initializer list for brevity)
    struct Student temp = {103, "Charlie Brown", 3.99};
    students[2] = temp; // Assign the temporary initialized struct

    // Step 4: Iterate through the array and print each student's details
    printf("--- All Student Details ---\n");
    for (int i = 0; i < MAX_STUDENTS; i++) {
        printf("Student %d:\n", i + 1);
        printf("  ID: %d\n", students[i].studentID);
        printf("  Name: %s\n", students[i].name);
        printf("  GPA: %.2f\n", students[i].gpa);
        printf("\n");
    }

    return 0;
