#include

#include

#include

#include

using namespace std;

int main() {

int t[] = { 3, 4, 2, 1, 6, 5, 7, 9, 8, 0 };

vector v(t, t + 10);

map m;

for (vector::iterator i = v.begin(); i != v.end(); i++) {

stringstream s;s << *i << *i;

m.insert(pair(*i, s.str()));

}

pair::iterator, map::iterator> range;

range = m.equal_range(6);

for (map::iterator i = range.first; i != range.second; i++) {

cout << i?>first << " ";

}

return 0;

}



Answer : A

Question 2

What happens when you attempt to compile and run the following code? Choose all possible answers.

#include

using namespace std;

class C {

public:

int _c;

C():_c(0){}

C(int c) { _c = c;}

C operator+=(C & b) {

C tmp; tmp._c = _c+b._c;

return tmp;

} };

ostream & operator<<(ostream & c, const C & v) {

c<

template

class A {

T_v;

public:

A() {}

A(T v): _v(v){}

T getV() { return _v; }

void add(T & a) { _v+=a; }

};

int main()

{

A b(2);

Aa (5);

a.add(C());

cout << a.getV() <

return 0;

}



Answer : A, C

using namespace std;

bool mycomparison (int first, int second){return first>second;}

template

void print(T start, T end) {

while (start != end) {

std::cout << *start << " "; start++;

}

}

int main()

{

int t1[] ={ 1, 7, 8, 4, 5 };

list l1(t1, t1 + 5);

int t2[] ={ 3, 2, 6, 9, 0 };

list l2(t2, t2 + 5);

l1.sort(mycomparison);

l2.sort(mycomparison);

l1.merge(l2,mycomparison);

print(l1.begin(), l1.end());

print(l2.begin(), l2.end()); cout<

return 0;

}



Answer : A
