CPP C++ Certified Professional Programmer - Practice Questions

Question 1 (Volume A)

Which method added to class B at the marked spot will allow the code below to compile? Choose all possible solutions.

#include

#include #include using namespace std; class B { int val; public:

B(int v):val(v){}

int getV() const {return val;}

/* Insert Code Here */

};

ostream & operator <<(ostream & out, const B & v) { out<struct Out { ostream & out;

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

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

int t[]={8, 10, 5, 1, 4, 6, 2, 7, 9, 3}; vector v1(t, t+10);

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