Answered Essay: Write a C++ program to list all elements in the Cartesian product of these two sets. You will ask user to ent

Hi Let me know if you need more information:-

========================================

#include <iostream>
using namespace std;

int main() {

string setA[30];
string setB[30];

char choice = ‘’;
do {
cout << “Enter integers for set A (no more than 30 numbers, -1 to stop)”
<< endl;
string input;
int i = 0;
while (1) {
cout << i << “:”;
cin >> input;
if (input == “-1”) {
break;
} else {
setA[i] = input;
}
i++;
}

cout
<< “Enter characters for set B (no more than 30 characters, ‘.’ to stop)”
<< endl;
int j = 0;
while (1) {
cout << j << “:”;
cin >> input;
if (input == “.”) {
break;
} else {
setB[j] = input;
}
j++;
}

cout << “set A = { “;
for (int k = 0; k < i; k++) {
cout << setA[k];
if (k < i – 1)
cout << “,”;
}
cout << ” }” << endl;

cout << “set B = { “;
for (int k = 0; k < j; k++) {
cout << setB[k];
if (k < j – 1)
cout << “,”;
}
cout << ” }” << endl;

cout << “The Cartesian product of A and B is” << endl;
cout << “A X B = { ” << endl;

for (int k = 0; k < i; k++) {
for (int l = 0; l < j; l++) {
cout << “( ” << setA[k] << “, ” << setB[l] << ” )”;
if ((l < j – 1) || (k < i – 1))
cout << “, “;
}
}
cout << “}” << endl;
cout << “Again (y/n):”;
cin >> choice;
} while (choice == ‘y’);
return 0;
}

===============

OUTPUT:-

=====================

Enter integers for set A (no more than 30 numbers, -1 to stop)
0:2
1:3
2:4
3:-1
Enter characters for set B (no more than 30 characters, ‘.’ to stop)
0:w
1:r
2:t
3:y
4:q
5:.
set A = { 2,3,4 }
set B = { w,r,t,y,q }
The Cartesian product of A and B is
A X B = {
( 2, w ), ( 2, r ), ( 2, t ), ( 2, y ), ( 2, q ), ( 3, w ), ( 3, r ), ( 3, t ), ( 3, y ), ( 3, q ), ( 4, w ), ( 4, r ), ( 4, t ), ( 4, y ), ( 4, q )}
Again (y/n):n
