Question

Modify the following code below and follow exactly all given instructions:

1) In the functions set_difference and set_complement eliminate all loop index variables (int i and i) with a pointer.

2) Use that pointer to do the exactly role as loop index variables (int i and i) does.

3) Do not modify any of the code below expect for replacing all loop index variables (int i and i) with a pointer to do the same job as a loop index variable would.

#include <stdio.h>

void set_difference(int *a, int *b, int n, int *difference);

void set_complement(int *a, int n, int *complement);

int main()

{

int sizeOfA;

int sizeOfB;

int n = 10;

int setA[10] = {0,0,0,0,0,0,0,0,0,0}, setB[10] = {0,0,0,0,0,0,0,0,0,0};

int diff[10] = {0,0,0,0,0,0,0,0,0,0}, Acomplement[10] = {0,0,0,0,0,0,0,0,0,0}, Bcomplement[10] = {0,0,0,0,0,0,0,0,0,0};

int i, ele;

printf("Please enter the number of elements in set A: ");

scanf("%d", &sizeOfA);

printf(" Enter the numbers in set A: ");

for(i = 0; i < sizeOfA; i++)

{

scanf("%d", &ele);

setA[ele] = 1;

}

printf(" Please enter the number of elements in set B: ");

scanf("%d", &sizeOfB);

printf(" Enter the numbers in set B: ");

for(i = 0; i < sizeOfB; i++)

{

scanf("%d", &ele);

setB[ele] = 1;

}

set_difference(setA,setB,n,diff);

printf(" Output: ");

printf(" The difference of set A and B is: ");

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

{

if(diff[i] == 1)

printf("%d ", i);

}

set_complement(setA,n,Acomplement);

printf(" The complement of set A is: ");

for(i = 0; i < 10; i++)

{

if(Acomplement[i] == 1)

printf("%d ", i);

}

set_complement(setB,n,Bcomplement);

printf(" The complement of set B is: ");

for(i = 0; i < 10; i++)

{

if(Bcomplement[i] == 1)

printf("%d ", i);

}

int i, ele;
printf("Please enter the number of elements in set A: ");
