Question

Write a C-based language program in visual studio that uses an array of structs that stores student information including name, age, GPA as a float, and grade level as a string (e.g., “freshmen,”).

Write the same program in the same language without using structs.

Answer 1

// do comment if any problem arises

1-> using structs

// code

#include <stdio.h>

#include <string.h>

// structure student

struct student

{

    char name[100];

    int age;

    float GPA;

    char grade[100];

};

int main()

{

    // creating array of 100structs

    struct student Students[100];

    //creating an example student

    strcpy(Students[0].name, "Harish");

    Students[0].age = 25;

    strcpy(Students[0].grade, "freshmen");

    Students[0].GPA = 8.1;

    //printing created student

    printf("First student:\nName: %s\n", Students[0].name);

    printf("Age: %d\nGPA: %.1f\nGrade: %s", Students[0].age, Students[0].GPA, Students[0].grade);

}

Output:

2-> without structs:

// code

#include <stdio.h>

#include <string.h>

int main()

{

    //for solving this problem without struct multiple arrays have to be used

    char name[100][100];

    int age[100];

    float GPA[100];

    char grade[100][100];

    //creating an example student

    strcpy(name[0], "Harish");

    age[0] = 25;

    strcpy(grade[0], "freshmen");

    GPA[0] = 8.1;

    //printing created student

    printf("First student:\nName: %s\n", name[0]);

    printf("Age: %d\nGPA: %.1f\nGrade: %s", age[0], GPA[0], grade[0]);

}

output:

It can be seen that both programs yields same output.
