Q.1. Let we have a class,

class String

{

char buf [25];

};

Write code for assignment (=) operator function which assign one String object to other object. Your code should also avoid self assignment.

 

Q2. Write a program which uses setflag function of cout to display hexadecimal and octal representation of number.

Q3: Write a program that defines a Template function named Square () which finds the square of a number and then return it. Define one variable of type int in main function and then call Square function on that.

Program output should look like this:

Enter an integer value to find its Square: 6
Square of integer number is: 36

Q4: What is the output of following code snippet.  (2)

// class templates
#include <iostream>
using namespace std;

template <class T>
class mypair {
T a, b;
public:
mypair (T first, T second)
{a=first; b=second;}
T getmax ();
};

template <class T>
T mypair<T>::getmax ()
{
T retval;
retval = a>b? a : b;
return retval;
}
int main () {
mypair <int> myobject (100, 75);
cout myobject.getmax();
system("pause");
}

Q5. Write output pf the given code   (2)

a=10 b=5 c=0

a+(2*5)+c/2

 

Q6.Can we call new operator inside constructor function?

Q7. We comment our program liberally. How comment help us? Also tell is they affect the performance.

Q8. what is the source and destination of cin stream?

Q9 and Q10:

 2 question thay jin mai code diya hua tha aur us ka output daina tha. template n string wala.questions

Output should be like this:

 

Adding numbers (don’t remember here what was written)

Enter first number:

12

Enter second number:

25

Sum=37

 

Q2: (Marks 5) Find the error in the program and then remove this. (Don’t remember the coding)

 

Q3: (Marks 5) Given the class Data

 

main()

{

            class Date

            {

private:

            int day, month, year;

public:

            day=01;

            month=10;

            year=2010

}

……………..Dont remember the lines

……………..

……………..

 

}

 

Use the dynamically allocation  (don’t remember what)

In the last also free memory allocation.

 

Q4: (Marks 3) Why goto is not recommended to use in programmes?

Q5: (Marks 2) Write two types of data conversions used for used defined data types.

Q6: (Marks 2) Write the following using logical operators:

1. number is both multiple of 4 and 6
2. number is even but not 8
3. answer is either N or n
4. don’t remember this

 

Q7: (Marks 3) Write the output of the following if “int 5” is passed to the variable:

Template <class T);

T reciprocal (T x);

{

return (1/x);

}

(it was like something. Don’t remember exactly)

 

Q8: (Marks 3): How can we determine that dynamically memory allocation has been set successfully or not is C++ using the new operator?
