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

#include

#include <algorithm>

#include

#include

#include

using namespace std;

class A {

int a;

public:

A(int a):a(a) {}

int getA() const { return a;} void setA(int a){ this?>a = a;}

bool operator < ( const A & b) const { return a

};

struct display { void operator() (const A & a) {cout << " " << a.getA();} };

struct add10

{

void operator() (A & a) { a.setA(a.getA()+10) ;}

};

int main() {

int t[] = { 10, 5, 9, 6, 2, 4, 7, 8, 3, 1 };

vector v1(t, t + 10);

set s1(t, t + 10);

for_each(v1.begin(), v1.end(), add10()); for_each(v1.begin(), v1.end(), display());

for_each(s1.begin(), s1.end(), add10()); for_each(s1.begin(), s1.end(), display());

return 0;

}
