C++ question!!! Your application should ask the user to enter up to 10 positive

Question

C++ question!!!

Your application should ask the user to enter up to 10 positive integers (including 0) for each set, and then provide an answer that shows the union and the intersection of the sets.

Requirements:

Your application should ask the user to enter up to 10 positive integers (including 0) for each set, and then provide an answer that shows the union and the intersection of the sets.

In the answer, the elements must be in ascending order. Assume that the user will not enter repeated number within the set. Assume that the user may enter the numbers not in order.

The user may choose not to enter any integers, in which case the set will be considered empty.

The process should be repeated until the user decides to quit.

You can choose any format for the output, as long as:

It has a title o It contains a description of what the application does.

It is clearly explanatory o It is written correctly (no spelling/grammar/punctuation errors)

It clearly identifies the sets by using curly brackets and commas and by naming them A and B.
