Homework SoursePlease assist in correcting the code below per the feedback
Please assist in correcting the code below per the feedback of -The data struct is backward: rather than having a struct that consists of arrays, you need to have an array of structs, where each struct holds the ID number and score. This will also make it possible to keep each grade associated with the correct ID when the program sorts the entries by ID number. You have not implemented this sort in your code. Remember that you are sorting data in an array of structs rather than simple values in an array.
ORIGINAL INSTRUCTIONS
Modify the grade book program to use a custom struct to hold the student\'s ID number and the percentage score for each item in the grade book. The program should accept the entry of ID numbers and percentage grades (0–100) until the user signals that he or she is done entering grades. The program should then print out the ID numbers and grades entered by the user, sorted by ID number.
#include <stdio.h>
#include <stdlib.h>
//Creating the GradeBook Structure
struct gradeBook {
//Declaring the student\'s Id array and Grade array
int id[100];
int grade[100];
} gradbk;
int main( )
{
//initialize variables
int i=0, j=0;
int id;
//infinite loop which will stop when user enters -1 as id value
while(id != -1)
{
//Getting the id entered by the user
printf(\"Enter student id number (Enter -1 to stop):\");
scanf(\"%d\",&id);
//if user entered id is not -1
if(id != -1)
{
//Populating the id into the id array
gradbk.id[i]=id;
//Getting the grade entered by the user
printf(\"Enter grade percentage (0-100) \");
//read grade
scanf(\"%d\",&gradbk.grade[i]);
i++;
continue;
}
//if user entered -1, then exit this loop
else
{
break;
}
}
//Displaying all the students id\'s and grades
printf(\"\ \ Displaying the Students ID\'s and Grades : \ \");
//loop which will iterate till no:of user entered grades
for(j=0; j<i; j++)
{
//print the students id\'s and grade
printf(\"\ Student id : %d \",gradbk.id[j]);
printf(\"\ Grade is : %d \",gradbk.grade[j]);
}
return 0;
}
