C++ Program

Ask for user input for a series of ordered pairs comprised of integers. Print out the relation, the domain, and range.

Provide some test cases.

The output should be properly formatted, though if you have a trailing "," it's not a big deal.

If the input was :

1 2

2 1

3 2

4 5

Output should look similar to the following:

Relation = {(1,2), (2,1), (3,2), (4, 5)}

Domain = {1, 2, 3, 4}

Range = {2, 1, 5}
