$How many line(s) that you need to change in the following code to make the queue a priority queue? #include <iostream> #include <queue> using namespace std; void showq (queue <int> gq) { queue <int> g = gq; while (!gq.empty()) { } cout << endl; } int main() { cout << gq. front () << " gq.pop(); queue <int> gquiz; gquiz.push(10); gquiz.push (20); gquiz.push(30); cout << "The queue gquiz is: "; showq (gquiz); return 0; Answer: How many syntax error(s) in the following class definition: class clockType { public: void setTime(int h, int m, int s); // Mutator function void getTime(int &h, int &m, ints) const; // Accessor function void printTime() const; // Accessor function void incHr(); // Mutator function void incMin(); // Mutator function void incSec(); // Mutator function //******************* // defining member(inside the class), friend(inside the class) and non- member(outside class) functions *********** bool equalTime_M(const clockType &C) const;//Accessor / constant function: is a binary function "==" friend bool equalTime_F(const clockType &C1, const clockType &C2); //Accessor constant function is a binary function "==" //********** // overloading the == relational operator as member function: bool operator==(const clockType &C) const; // overloading the + relational operator as member function: clockType operator+(const clockType &C) const; // overloading the == relational operator as friend function: friend bool operator!=(const clockType &C1, const clockType &C2); // overloading the + relational operator as friend function : friend bool operator-(const clockType& C1, const clockType& C2); //****** clockType(); // constructor without parameters "default constructor" clockType(Brand name, int h, int m=0, int s=0); // constructor with parameters clockType(string s1, string s2, int h, int m=0, int s=0); ~clockType(); // destructor "used to free resources" Answer: private: // can ONLY be accessed within the class, or within its function members!! //data members int hr, min, sec; Brand BN; //composition of a structure object };$
