Run the attached Set_3_Test.cpp to test your code. The output of the program has to be exactly the same to the Expected output below. Instruction is in the attached file. Need the “Set.h” file for this HW mainly. Expected output: int arr1[] = {2, 1, 4, 3, 5, 4} Set1(arr1): {2,1,4,3,5} adding +1, +3, +5 again then +6 and +7 Set1: {2,1,4,3,5,6,7} Remove(-7); Remove(-9) Set1: {2,1,4,3,5,6} Creating set2, copying the former set. (Testing copy constructor) Set2: {2,1,4,3,5,6} Set3: {0,1,4,9} The union of set2 and set3 is: ~Set() ~Set() {2,1,4,3,5,6,0,9} The intersection of set2 and set3 is: ~Set() ~Set() {1,4} The difference between unionSet and intersectSet is: diffSet = unionSet.Difference(intersectSet) ~Set() ~Set() {2,3,5,6,0,9} Set4(set1): {2,1,4,3,5,6} set1: {2,1,4,3,5,6} set4: {2,1,4,3,5,6} ~Set() ~Set() set1 is equal to set4 set1: {2,1,4,3,5,6} set3: {0,1,4,9} ~Set() ~Set() set1 is not equal to set3 ~Set() ~Set() ~Set() ~Set() ~Set() ~Set() ~Set()
