Q.1)Write a C++ program to create a
class Worker with data members as Worker_Name, No_of_Hours_worked, Pay_Rate.
Write necessary member functions to calculate and display the salary of worker.
(Use default value for Pay_Rate)
#include<stdio.h>
#include<iostream.h>
#include<conio.h>
class worker
{
char
name[10];
int
hr;
public:
void
accept()
{
cout<<"enter
name";
cin>>name;
cout<<"enter
hours";
cin>>hr;
}
void calculate(int rate=20)
{
cout<<"salary
of worker is Rs."<<(hr*10)*rate;
}
};
void main()
{
worker
w;
clrscr();
w.accept();
w.calculate();
getch();
}
Another way
#include<iostream.h>
#include<conio.h>
class worker
{
public:
char worker_name[20];
int salary,hrworked,pay_rate;
void calsalary(int pay_rate=25)
{
cout<<"Enter worker name\t";
cin>>worker_name;
cout<<"Enter number of hours worked\t";
cin>>hrworked;
salary=pay_rate*hrworked;
cout<<"\nWorker name :-\t"<<worker_name;
cout<<"\nSalary :-\tRs."<<salary;
}
};
void main()
{
clrscr();
worker w;
w.calsalary();
getch();
}
Q.2)Create class Person which contains data member as Passport_Id,
Person_name,
Nationality, Gender,
Date_of_Birth, Date_of_Issue, Date_of_expiry .
Write a c++ program to perform
following member functions:
i. Enter
details of all persons
ii. Display
passport details of one person
iii. Display
passport details of all persons
(Use Function overloading and Array of
object).
#include<iostream.h>
#include<conio.h>
#include<stdlib.h>
class Person
{
int Passport_id;
char Person_name[20];
char Nationality[20];
char Gender[20];
char Date_of_Birth[30];
char Date_of_Issue[30];
char Date_of_Expiry[30];
public:
void getdata();
void display(Person,int);
void display();
};
void Person::getdata()
{
cout<<"\n\nEnter the Passport id of the Person:";
cin>>Passport_id;
cout<<"\nEnter the name of the Person:";
cin>>Person_name;
cout<<"\nEnter the Nationality of the person:";
cin>>Nationality;
cout<<"\nEnter the Gender of the Person:";
cin>>Gender;
cout<<"\nEnter the Date of Birth:";
cin>>Date_of_Birth;
cout<<"\nEnter the Date of Issue:";
cin>>Date_of_Issue;
cout<<"\nEnter the Date of Expiry:";
cin>>Date_of_Expiry;
}
void Person::display(Person a,int num)
{
if((num==a.Passport_id)==1)
{
cout<<"\nPassport Details Are:";
cout<<"\n\nPassport ID:"<<a.Passport_id;
cout<<"\nPerson Name:"<<a.Person_name;
cout<<"\nNationality:"<<a.Nationality;
cout<<"\nGender:"<<a.Gender;
cout<<"\nDate of Birth:"<<a.Date_of_Birth;
cout<<"\nDate of Issue:"<<a.Date_of_Issue;
cout<<"\nDate of Expiry:"<<a.Date_of_Expiry;
}
}
void Person::display()
{
cout<<"\n*********** Passport Details Are ***********";
cout<<"\nPassport ID:"<<Passport_id;
cout<<"\nPerson Name:"<<Person_name;
cout<<"\nNationality:"<<Nationality;
cout<<"\nGender:"<<Gender;
cout<<"\nDate of Birth:"<<Date_of_Birth;
cout<<"\nDate of Issue:"<<Date_of_Issue;
cout<<"\nDate of Expiry:"<<Date_of_Expiry;
}
int main()
{
clrscr();
int num,ch,k,l;
Person p[10];
cout<<"\n********** MENU ***********";
cout<<"\n1.Enter Details of all Person";
cout<<"\n2.Display Passport Details of one Person";
cout<<"\n3.Display Passport Details of all Person";
cout<<"\n4.Exit.";
do
{
cout<<"\nEnter your choice:";
cin>>ch;
switch(ch)
{
case 1:
cout<<"\nHow many records you wish to enter:";
cin>>k;
for(int i=0;i<k;i++)
{
p[i].getdata();
}
break;
case 2:
cout<<"\nEnter the Passport ID to check records:";
cin>>l;
for(i=0;i<k;i++)
{
p[i].display(p[i],l);
}
break;
case 3:
cout<<"\n************ Passport Details
****************";
for(i=0;i<k;i++)
{
p[i].display();
}
break;
case 4:
exit(0);
default:
cout<<"\nYou entered wrong choice:";
}
}while(ch!=4);
getch();
return 0;
}
