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

#include <string>
#include <list>
#include <iostream>
using namespace std;
template<class T> void print(T start, T end) {
while (start != end) {
std::cout << *start << " "; start++;
}
}

int main() {
string t1[] = { "1", "2", "3", "4", "5", "6", "7", "8", "9", "10"};
list<string> l1(t1, t1 + 10);
list<string> l2(l1);
l2.reverse(); l1.splice(l1.end(),l2);
l1.unique();
print(l1.begin(), l1.end()); cout<<endl;
return 0;
}

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

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;

int main () {
int t[] = {1,2,3,4,5,1,2,3,5,4};
vector<int> v (t,t+10);
vector<int>::iterator it;
int m1[] = {1, 3, 2};
it = find_end (v.begin(), v.end(), m1, m1+3);
if (it != v.end())
cout << "Found at position: " << it?v.begin() << endl;
return 0;
}

What will happen when you attempt to compile and run the code below, assuming that file test.in contains the following sequence: 1 2 3?

#include <iostream>
#include <fstream>
#include <string>
#include <list>
#include <algorithm>
using namespace std;
template<class T>struct Out {
ostream & out;
Out(ostream & o): out(o){}
void operator() (const T & val ) {out<<val<<" "; } };

int main () {
ifstream f("test.in");
list<int> l;
for( ; f.good() ; ) {
int i;
f>>i;
l.push_back(i);
}
f.close();
for_each(l.begin(), l.end(), Out<int>(cout));
return 0;
}

Program will output:

return 0;
}

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