Question

Plz help!! The programming language is C and could you write comments as well?

Problem 2. Calculate Grades (35 points) Arrays can be used for any data type, such as int and char. But they can also be used for complex data types like structs. Structs can be simple, containing simple data types, but they can also contain more complex data types, such as another struct. So you could have a struct inside of a struct. This problem deals with both. Write a program that inputs the information of the students for a whole class, calculates the final grade and prints, for each student their grade and whether they passed (final grade larger or equal than 50) To calculate the grade you have to get the average and factor that for 95% and the other 5% is the attendance. Maximum attendance is 25. Then use a square root curve "Texas curve", see You have to find a function that performs the square root and the flooring in a C library and use it. Final_grade-floor of (10 x square_root(avg_grades x 0.95 + ((attendance/MAX_ATTENDANCE)*100) x 0.05)) Sample Input Sample Output Number of Students: 2 23 10 50 60 50 60 234 25 20 30 10 20 UIN- 123 final_grade- 73.00 PASS UIN- 234 final_grade- 48.00 FAIL Number of Students: 4 123 1 90 85 96 100 234 25 20 10 15 8 345 10 60 40 35 70 456 25 100 100 100 100 UIN-123 final_grade 93.00 PASS UIN 234 final_grade-41.00 FAIL UIN-345 final_grade 71.00 PASS UIN-456 final_grade-100.00 PASS Input in order is: UIN, attendance, and 4 test grades Create a Grades struct that contains a test grades, the attendance and the final grade Create a Student struct that contains the uin and the struct Grades Create a function "void inputStudent(Student "s) that reads with scanf all the parameters of a student (in the order specified in the first bullet). Call that in a loop from the main depending on how many students you have Create a function "void calculateGrades(Student classll, int nStudents)" that for each student calculates and sets the final grade (stored in the Grades struct from that student) using the formula above Create a function "printGrades(Student class[], int nStudents)" that prints the UIN, final grade and whether they PASS or FAIL, exactly as shown in the table

Answer 1

#include <stdio.h>

#include <stdlib.h> //For using the malloc() function

#include <math.h> //For using sqrt() and floor() functions

struct Grades      //Creating the structure Grades

{

                int attendance;

                float final_grade;

                int test_grades[4]; //For storing the four test grades

               

};

{

    int UIN;

    struct Grades grades;

};

void inputStudent(struct Student *s) //For inputting the information of student

    scanf("%d",&s->UIN);

    scanf("%d",&s->grades.attendance);

    scanf("%d",&s->grades.test_grades[0]);

    scanf("%d",&s->grades.test_grades[1]);

    scanf("%d",&s->grades.test_grades[2]);

    scanf("%d",&s->grades.test_grades[3]);

}

void calculateGrades(struct Student class[],int nStudents) //For calculating the grades of each student

{

    int i,attendance,max_attendance=25,avg_grades;

    float final_grade;

        attendance=class[i].grades.attendance;

       

        final_grade=floor(10 * sqrt(avg_grades*0.95 + (attendance/max_attendance)*5));

        printf("final_grade=%.2f ",class[i].grades.final_grade);

       

        if(class[i].grades.final_grade >=50 )

            printf("PASS");

        else

            printf("FAIL");

    }

}

int main()

{

    int nStudents,i;

    struct Student *class;   //Declaring the pointer variable which will work as a array

   

    printf("Number of Students: ");

    scanf("%d",&nStudents);

   

    class = (struct Student *) malloc(sizeof(struct Student)*nStudents); //Allocating memory to the pointer variable

   

    for(i=0;i<nStudents;i++) //Looping through the no of students for inputting the information

        inputStudent(&class[i]);

   

    calculateGrades(class,nStudents); //Calling the function to calculate final_grade of each studennt

   

    printGrades(class,nStudents); //Calling the function to print the UIN, final_grade and PASS/FAIL

   

    return 0;
