CS201-Introduction to Programming.. Todays Paper(01/03/2014)..

1) Write a simplest program using getline functions of an object to read a sentence from the keyboard and then print it on the screen. (2)

2)In how many ways a many a unary operator can be overloaded for a class. write down the decription of each way.(2)

3)What are advantages and disadvantages of using macros over functions.(2)

4)Write down the piece of code that will declare a matrix of 3*3 and initialize all its elements with 0. (2)

5)Write the c++ code for declaration of overloaded stream exertion >> and stream insertion operator for the object d of type date.(3)

6) Friendship in classes or functions is granted or taken. How it is granted or taken.(3)

7)Which array operator is used to determine the size of a data type or a variable in the memory (3)

8)How name mangling technique is used by compiler and for what purpose it is used.? (5)

9) Write a program that defines a Tempelate function named Square() which finds the square of a number and then return it. Define one veriable of type float in main function and then call square function on that. Program output should look like this. (5)

" Enter a float value to find its square: 12.3 "

" Square of float numbers is: 151.29 "

10) Given is the code for class myClass (5)

{

                private:

                int x,y;

                public:

                myclass()

                {

                x=0;

                y-0;

                }

};

You are requierd to performfollowing task in the main() function.

Prompt the user to enter the number of objects to be created.

Dynamicaly allocate memory to objects according to the size entered by the user.

Deallocates memory that was allocated to objects.

11) code of date class (5)

class Date

{

                private:

                int day, month year;

                public:

                Date()

{

                day=01;

                month=01;

                year=2000;

}

void display()

{

                coutdaymonthyear;

}

};

write the code for dynamicaly creating the array of 10 objects of type Date (using default contructer) and then using loop , call the diplay() function for each of the using loop, call the display() function for each of the objects , In the end , deallocates the memory allocated in objects..... (5)

Remember me in your prayers..
