1 The correct answer is :-

#include "ClassRoom.h"

void ClassRoom::Print() const

Explanation:- The first code snippet is a header file which contains the class declaration.So it is included in the second file

As the function Print is defined outside the class,we need to use the scope resolution operator syntax to denote that it belongs to the class.

2 The correct answer is:- tmpNext = this->nextNodePtr;
this->nextNodePtr = nodeLoc;
nodeLoc->nextNodePtr = tmpNext;

Explanation:-

As nextNodePtr is not passed into the method,so it must be a class member.The this pointer helps to access a class member and the syntax is always this-> followed by member name.

3 The correct answer is:-

Soccer::Team SoccerTeamMembers

BasketBall:Team BasketBallTeamMembers

Explanation:- Only way to access entities (variables or classes ) inside namespaces is using the scope operator.All other options are hence invalid

4  The correct answer is:- void Student::Display()

  Explanation:- The correct syntax is <classname> + scope resolution operator + <method name>

5 The correct answer is:- push_back()

Explanation:- Doesn't need sort() as the numbers are to be printed any order. append() is used in case of strings,so not applicable,at() function is used to fetch a value at a certain position from a vector,so not applicable either.
