CLASS and OBJECTS

CLASS and OBJECTS

1.Give the output of the following program ( Assuming that all required header files are  included in the program )     :              

 class TEMP
{ static int a;
float b;
public:
TEMP( )
{ b=10; }
void INTEMP( )
{ a++;
b=a+10; }
void OUTTEMP( )
{ cout<<a*i<<"$"<<b-3<<endl; } };
int TEMP::a=2;
void main()
{ TEMP ob[5];
for(int x=1;x<5;x++)
ob[x].INTEMP( );
for(x=1;x<5;x++)
ob[x].OUTTEMP( );} 

2.  Define a class Travel in C++ with the description given below:
Private Members:
T_Code of type string
No_of_Adults of type integer
No_of_Children of type integer
Distance of type integer
TotalFare of type float
Public Members:
A constructor to assign initial values as follows :
T_Code with the word “NULL”
No_of_Adults as 0
No_of_Children as 0
Distance as 0
TotalFare as 0
A function AssignFare( ) which calculates and assigns the value
of the data member TotalFare as follows :
For each Adult
Fare (Rs)       For Distance (Km)
500                    >=1000
300                    <1000 & >=500
200                         <500

For each Child the above Fare will be 50% of the Fare mentioned in the above table.
For example :
If Distance is 750, No_of_Adults = 3 and No_of_Children = 2
Then TotalFare should be calculated as
No_of_Adults * 300 + No_of_Children * 150
i.e. 3 * 300 + 2 * 150 = 1200
• A function EnterTraveK ) to input the values of the data members
T_Code, No_of_Adults, No_of_Children and Distance; and invoke the AssignFare( )
function.
• A function ShowTraveK) which displays the content of all the data members for a
Travel.

3. Define a class TEST in C++ with following description:
Private Members
• TestCode of type integer
• Description of type string
• NoCandidate of type integer
• CenterReqd (number of centers required) of type integer
• A member function CALCNTR() to calculate and return the number of centers as
(NoCandidates/100+1)
Public Members
• A function SCHEDULE() to allow user to enter values for TestCode, Description,
NoCandidate & call function CALCNTR() to calculate the number of Centres
• A function DISPTEST() to allow user to view the content of all the data members.

4. Define a class Clothing in C++ with the following descriptions:
Private Members:
Code of type string
Type of type string
Size of type integer
Material of type string
Price of type float
A function Calc_Price() which calculates and assigns the value of Price as
follows:
For the value of Material as “COTTON”
Type Price            (Rs.)
TROUSER          1500
SHIRT                  1200
For Material other than “COTTON” the above mentioned Price gets  reduced by 25%.
Public Members:
A constructor to assign initial values of Code, Type and Material with the word “NOT ASSIGNED” and Size and Price with 0. A function Enter () to input the values of the data members Code, Type,
Size and Material and invoke the CalcPrice() function. A function Show () which displays the content of all the data members for a Clothing. 

5. Define a class TAXPAYER in C++ with following description :                             For - 4 Marks
Private members :

1. Name  of type string
2. PanNo of type string
3. Taxabincm (Taxable income) of type float
4. TotTax of type double
5. A function CompTax( ) to calculate tax according to the following slab:

Taxable Income                              Tax%
      Up to 160000                                  0
      >160000 and <=300000                 5
      >300000 and <=500000                 10
      >500000                                         15
Public members :

• A parameterized constructor to initialize all the members
• A function INTAX( ) to enter data for the tax payer and call function CompTax( ) to assign TotTax.
• A function OUTAX( ) to allow user to view the content of all the data members.

6. Find the output of the following C++ program:

#include<iostream.h>

#include<conio.h>

#include<ctype.h>

class Class

{

int Cno,total;

char section;

public

:

Class(int no=1)

{

Cno=no;

section='A';

total=30;

}

void addmission(int c=20)

{

section++;

total+=c;

}

void ClassShow()

{

cout<<Cno<<":"<<section<<":"<<total<<endl;

}

} ;

void main()

{

Class C1(5),C2;

C1.addmission(25);

C1.ClassShow(); 

C2.addmission();

C1.addmission(30);
