instructions.

Answer 1

Answer:

please elaborate the question more ans also send the input.

Answer 2

Answer:

struct Student {

char* name;

int id;

char age;

};

// setting up rules for comparison

// to sort the students based on ID

int comparator(const void* p, const void* q)

{

return (((struct Student*)p)->id - ((struct Student*)q)->id);

}

// Driver program

int main()

{

int i = 0, n = 5;

struct Student arr[n];

// Get the students data

arr[0].id = 1;

arr[0].name = "bd";

arr[0].age = 12;

arr[1].id = 2;

arr[1].name = "ba";

arr[1].age = 10;

arr[2].id = 3;

arr[2].name = "bc";

arr[2].age = 8;

arr[3].id = 4;

arr[3].name = "aaz";

arr[3].age = 9;

arr[4].id = 5;

arr[4].name = "az";

arr[4].age = 10;

// Print the Unsorted Structure

printf("Unsorted Student Records:\n");

for (i = 0; i < n; i++) {

printf("Id = %d, Name = %s, Age = %d \n",

arr[i].id, arr[i].name, arr[i].age);

}

// Sort the structure

// based on the specified comparator

qsort(arr, n, sizeof(struct Student), comparator);

// Print the Sorted Structure

printf("\n\nStudent Records sorted by ID:\n");

for (i = 0; i < n; i++) {

printf("Id = %d, Name = %s, Age = %d \n",

arr[i].id, arr[i].name, arr[i].age);

}

return 0;

}
