![1. Define : class , object
2. What is inline function?What points should you take care while making a
function inline?
3. What do you understand by Copy constructor? Specify two instances when
copy constructor is invoked?
4. Two overloaded functions are defined as:
void choice (char, char); -(1)
void choice (int , float); -(2)
Which of functions will be called by following calls.
choice(‘A’, 10);
choice (10.5, 10.5);
5) Name the header files to which following standard functions belong:
i) random() ii) gotoxy() iii) getc() iv) strcmpi()
6) Declare class height containing data members to store height of a person in feet
and inches.
Add suitable member functions to:
Read height of a person
Display height
Find and return taller out of two person’s height given as input to functions.
Convert height in cms.
7) Answer the questions a and b after going through the code :
class exam
{
int mark ;
char sub [ 30 ];
public :
exam ( ) Function 1
{
marks = 0 ;
strcpy ( sub , “ computer “ );
}](https://image.slidesharecdn.com/xiicompschw-100402225152-phpapp01/85/Xii-Compsc-Hw-1-320.jpg)
![exam ( char s [ ] ) Function 2
{
marks = 0 ;
strcpy ( sub , s );
}
exam ( int m ) Function 3
{
marks = m ;
strcpy( sub , “ c ++ “ );
}
exam ( char s [ ] , int m ) Function 4
{
marks = m ;
strcpy ( sub , s );
}
}
a. Write statements to execute all four functions (1)
b. Can we over load a destructor . (1/2)
c. What concept of OOPS is demonstrated by the four functions (1/2)
8) Define a class ELECTION with the following specifications . Write a suitable main ( ) function
also to declare 3 objects of ELECTION type and find the winner and display the details .
(3)
Private members :
Data : candidate_name , party , vote_received
Public members :
Functions : enterdetails ( ) – to input data
Display ( ) – to display the details of the winner
Winner ( ) – To return the details of the winner trough the object
after comparing the votes received by three candidates .
9) Give any two characteristics of constructors and destructors.
10) Explain default constructor ans constructor with default values.](https://image.slidesharecdn.com/xiicompschw-100402225152-phpapp01/85/Xii-Compsc-Hw-2-320.jpg)
