operator overloading

c++

part 1:

Complete the definition of the class given below such that the main program runs successfully. Make sure that your program doesnt consume extra memory space and it should not leak any memory.

class Set{

private:

int* elements; //To save elements of a Set

int size; //Total number of elements in a Set

};

void main()

{

int arr1[] = {10,20,30,40};

Set s1(arr1 , 4);//Creates a Set with elements of arr1 and size = 4

int arr2[] = {5,15,55};

Set s2(arr2 , 3);//Creates a Set with elements of arr2 and size = 3

cout<<"Set 1:\t"<

Set s3;

s3 = s1+s2; //Takes sorted Union of s1 and s2

cout<<"Set 3:\t"<

int arr3[] = {1,2,100,-1}; //-1 is delimiter

s3 = arr3 + s1; //Returns sorted Union

cout<<"Set 3:\t"<

cout<

cout<

}

part 2:

Write exact sequence of function calls for following code:

part 2:

s3 = arr1 + s2 + arr3;
