Тест №4 (полиморфизм). Пример.

Что будет выведено в стандартный поток в результате выполнения программы?

1)---------------------------------------------------------
void main()
{
	list<int> x;

	for(int i=0; i<=5; i++)
	{
		x.push_back(i);
	}
	
	x.sort();
	list<int>::iterator it=find(x.begin(), x.end(), 2);
	
	while(it != x.end())
	{
		cout<<*it++<<',';
	}
}

2)---------------------------------------------------------
void main()
{
	map<string, int, greater<string> > week;
	
	week["Mondey"]=1;
	week["Tuesday"]=2;
	week["Wednesday"]=3;
	week["Thursday"]=4;

	map<string, int, greater<string> >::iterator first_it=week.begin(), last_it=week.end();

	while( first_it != last_it)
	{
		cout << first_it->first << '-' << first_it->second <<' ';
		first_it++;
	}
}

3)---------------------------------------------------------
