CS304 Current Final Term Paper Fall 2013 File 9

1. What do you know about function templates? Describe it briefly.

1.  Explain the statement below,

vector<int> ivec(4, 3);

1. Give the name of two basic types of containers collectively called First class containers?

1. What is difference between simple association and aggregation?

1. Enlist the kinds of association with respect to Cardinality.

1. Identify and correct the syntax error(s) in the given code snippet?

template<classname T>
class Template_class {

                   private:
                   T data;
                   //…
                   Public:
                             //…
                    void input();
           };
template< class T >
void Template_class::input(  ) {
cin>>data;
}
void main()
{
Template_class <int>obj;
obj.input();
}

1. 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().

1. Give the general syntax of nested try catch blocks?

1. Consider the following code:

class Tutor{
int id;
char * name;
public:
Tutor(int, char*){
-------
-------
}
Tutor(const Tutor & obj){
------
------
}
};
Implement copy constructor for the Tutor class by shallow copy and by deep copy.

10. What would be the output of this code?

class mother {
  public:
    mother ()
      { cout "mother: no parameters\n"; }
    mother (int a)
      { cout "mother: int parameter\n"; }
};

class daughter : public mother {
  public:
    daughter (int a)
      { cout "daughter: int parameter\n\n"; }
};

class son : public mother {
  public:
    son (int a) : mother (a)
      { cout "son: int parameter\n\n"; }
};

int main () {
  daughter rabia (0);
  son salman(0);

  return 0;
}

11. 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;
 }

12. Write C++ code for the constructor of following template Vector class.

template< class T >
class Vector {
private:
        T* ptr;
        int size;
        int index;
public:
        Vector( int = 10 );  // constructor  
};
