Question

Create a C structure which stores information about a student. Each student should be represented by a student ID (integer), first name, last name, day, month and year of birth, and program code (string). Write a C program which creates an array of 100 of these structures, then prompts the user to enter data from the keyboard to fill the array. If an ID of 0 is entered, data entry should finish, and the list of students should be printed to the screen.

CODE -

#include<stdio.h>

// Create a struct for student

struct student

{

    int student_id;

    char first_name[20];

    char last_name[20];

    int day_birth;

    int month_birth;

    int year_birth;

    char program_code[20];

};

// Main Function

int main()

{

    // Create an array of 100 structs of student

    struct student students[100];

    int i=0;

    // Read input from the user for different students till user wants to quit by entering 0 as student id

    while(i<100)

    {

        printf("\nEnter the ID of student %d: ", i+1);

        scanf("%d", &students[i].student_id);

        // Break out of loop if 0 is entered as student id

        if(students[i].student_id == 0)

            break;

        printf("Enter the first name of student %d: ", i+1);

        scanf("%s", &students[i].first_name);

        printf("Enter the last name of student %d: ", i+1);

        scanf("%s", &students[i].last_name);

        printf("Enter the day of birth of student %d: ", i+1);

        scanf("%d", &students[i].day_birth);

        printf("Enter the month of birth of student %d: ", i+1);

        scanf("%d", &students[i].month_birth);

        printf("Enter the year of birth of student %d: ", i+1);

        scanf("%d", &students[i].year_birth);

        printf("Enter the program code of student %d: ", i+1);

        scanf("%s", &students[i].program_code);

        i++;

    }

    // Display student details

    printf("\nStudent Details:\n\n");

    for(int j=0; j<i; j++)

    {

        printf("\nStudent %d\n\n", j+1);

        printf("ID: %d\n", students[j].student_id);

        printf("First Name: %s\n", students[j].first_name);

        printf("Last Name: %s\n", students[j].last_name);

        printf("Date of Birth(dd-mm-yyyy): %d-%d-%d\n", students[j].day_birth, students[j].month_birth, students[j].year_birth);

        printf("Program Code: %s\n", students[j].program_code);

    }

    return 0;

}
