Question No. 1

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

#include

using namespace std;

int main(){

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

string first[] = {"three", "four", "two", "one", "six","five", "seven", "nine","eight"," ten"};

multimap m;

for(int i=0; i<10; i++) {

m.insert(pair(second[i],first[i]));

}

if (m[11] == "eleven") {

cout<<"eleven ";

}

for(multimap::iterator i=m.begin();i!= m.end(); i++) {

cout<second<<" ";

}

cout<

return 0;

}

Aprogram outputs: one two three four five six seven eight nine ten 11

Bprogram outputs: one two three four five six seven eight nine ten 10

Cprogram outputs: one two three four five six seven eight nine ten 10

Dprogram outputs: eleven one two three four five six seven eight nine ten 10

Question No. 2

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

#include

using namespace std;

templatestruct Out {

ostream & out;

Out(ostream & o): out(o){}

void operator() (const T & val ) { out<

template struct Sequence {

T start; T step;

Sequence(T start, T step):start(start), step(step){}

T operator()() { T v = start; start+=step; return v; } };

bool Less(float a, float b) { return int(a)

int main() {

float t[]={2.28, 1.66, 1.32, 3.94, 3.64, 2.3, 2.98, 1.96, 2.62, 1.13};

vector v1; v1.assign(t, t+10);

stable_sort(v1.begin(), v1.end(), Less);

for_each(v1.begin(), v1.end(), Out(cout));cout<

return 0;

}

Program outputs:

A1.66 1.32 1.96 1.13 2.28 2.3 2.98 2.62 3.94 3.64

B1.13 1.32 1.66 1.96 2.28 2.3 2.62 2.98 3.64 3.94

Ccompilation error

D3.94 3.64 2.98 2.62 2.3 2.28 1.96 1.66 1.32 1.13

};

template

A:A(T v):_v(v) {}
int main()
{
A<int> a(2);
cout<<1<<endl;

void operator() (const T & val ) { out<

int main() {

int t1[]={3,2,4,1,5};

int t2[]={5,6,8,2,1};

vector v1(10);

sort(t1, t1+5);

set_symmetric_difference(t1,t1+5,t2,t2+5,v1.begin());

for_each(v1.begin(), v1.end(), Out(cout));cout<

return 0;

}
