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..
