What happens when you attempt to compile and run the following code?

#include <deque>
#include <iostream>
#include <algorithm>
#include <set>
using namespace std;
template<class T>struct Out {
ostream & out;
Out(ostream & o): out(o){}
void operator() (const T & val ) { out<<val<<" "; }
};
bool Compare(char a, char b) { return tolower(a) < tolower(b);}
int main() {
char s[]={"qwerty"};
char t1[]={"ert"};
char t2[]={"ERT"};
sort(s, s+6);
cout<<includes(s,s+6, t1,t1+3, Compare)<<" "<<includes(s,s+6, t2,t2+3, Compare)<<endl;
return 0;
}
