N=random(2);
cout<<Arr[N]+Chance<<”#”;
}
(i) 9#6#
(ii) 19#17#
(iii) 19#16#
(iv) 20#16#
2. (a) What is the difference between nesting or containership and inheritance? Explain with example?
[2]
(b) Answer the question (i) and (ii) after going through the following class: [2]
class Travel
{
intPlaceCode; char Place[20]; float Charges;
public:
Travel( ) //Function 1
{
PlaceCode=1; strcpy(Place,”DELHI”);Charges=1000;
}
voidTravelPlan(float C ) // Function 2
{
cout<<PlaceCode<<“:”<<Place<<”:”<<Charges<<endl;
}
~Travel( ) // Function 3
{
cout<<”Travel Plan Cancelled”<<endl;
}
Travel(intPC,char p[ ],float C) // Function 4
{
PlaceCode=PC;strcpy(Place,P);Charges=c;
}
};
(i) In Object Oriented Programming, what is Function 1 and Function 4 combined together
referred as?
(ii) In Object Oriented Programming, which concept is illustrated by Function 3? When is this
function called/invoked?
(c) Define a class report with the following specification: [4]
Private members:
adno 4 digit admission number
name 20 characters
marks an array of 5 floating point values
average marks obtained
getavg() to compute the average obtained in five subjects
Public members:
read info() function to accept values for adno, name, marks, and invoke the function getavg().
display info() function to display all data members on the screen you should give function
definitions.
