Todays My CS304 Exam Questions 

How can we set the default values for non type parameters? 

Describe three properties necessary a container to implement generic algorithms. 

Write three important features of virtual functions. with example

The least one advantage and Disadvantage of Template 

 Give the names of two types of containers basically known as first class containers

Consider the code below, 

template< typename T > 

class T1 {  

    public: 

    T i; 

    protected: 

    T j; 

    private: 

    T k; 

    friend void Test(); 

    }; 

     

This code has a template class T1 with three members i,j and k and a friend function Test(), you have to 

describe which member/s of T1 will be available in function Test(). 

What is the output produced by the following program? 

#include<iostream.h> 

 

void sample_function(double test) throw (int); 

 

int main() 

{ 

  try 

  { 

    cout <<"Trying.\n"; 

    sample_function(98.6); 

    cout << "Trying after call.\n";  

 

  } 

  catch(int) 

  { 

    cout << "Catching.\n"; 

  } 

   

  cout << "End program.\n"; 

  return 0; 

} 

void sample_function(double test) throw (int) 

{ 

  cout << "Starting sample_function.\n"; 

  if(test < 100) 

     throw 42; 

} 

 

See the 5 code snippets below and tell whether these are correct or incorrect also justify your answers in the 

table given at the end.  

 

Snippet No.1 

 

template< class T> 

class A { 

} ; 

template< class T > 

class B : public A< T* > 

{ … } 

 

Snippet No.2 

 

template< > 

  class B< int* > : public A< T* > 

  { … }   

 

   

 

Snippet No.3 

class B : public A< T* >  

  { … }   

Snippet No.4 

  template< > 

  class B< char* > : public A 

  { … }; 

 

Snippet No.5 

template< class T > 

class B : public A< T* > 

{ … }
