set

I have a test tomorrow that I am revising for and the lecturer has supplied some sample questions with no answers. I was hoping I could get some help with a couple of them. I've written what I think the answer is for them.

1. What is the type of the set {1, 2, 3}?

integer/number

2. What is the type of the set {{1}, {2}, {3}}?

integer/number (unsure what putting each number in {} does?)

3. What is the type of the set {{1}, {2}, {3}, empty}?

integer/number

4. What is the type of the set {1, {2}, 3}? — is it well typed?

integer/number

5. What is the type of the set {1, 2, john}? — is it well typed?

unsure for a mixed set. Taking a complete guess of void or empty.

Any help will be much appreciated.

Hi Is there a better way of appending a set to another set than iterating through each element ? i have : set<string> foo ; set<string> bar ; ..... for (set<string>::const_iterator p = foo.begin( );p != foo.end( ); ++p) bar.insert(*p); Is there a more efficient way to… >>> More
