Thread: Sets and Lists

What is the difference between using sets and lists? A set is ordered and cannot contain duplicates? When I look up the syntax on cppreference.com, they basically have the same code written down for set and list examples (for examples under set they use list<chat> and no mention of set<char> - here)

Here is some simple code I have that I wanted to loop through all the items in a set and print them out. When I use the above code it works (using list) but this code is giving me compiler errors:

Code:

#include <iostream>
#include <set>
#include <list>

int main()
{
    int myInts[] = {1, 2, 3, 4};
    set<int> iSet(myInts, myInts+5); // line 8

    set<int>::iterator theIterator; // line 10
    for(theIterator = iSet.begin(); theIterator != iSet.end(); theIterator++)
    {
        cout << *theIterator << "\n";
    }

    system("Pause");
    return 0;

}

Code:
