Question

c++ programming language

Instructions In this exercise, you will design the class memberType. Each object of memberType can hold the name of a person, member ID, number of books bought, and amount spent. Include the member functions to perform the various operations on the objects of memberType—for example, modify, set, and show a person’s name. Similarly, up-date, modify, and show the number of books bought and the amount spent. Add the appropriate constructors. Write the definitions of the member functions of memberType. Write a program to test various operations of your class memberType.

Answer 1

Here I am providing the answer for the above question:

Code:

#include <iostream>

using namespace std;

class memberType
{
public:
string personName; //data variables
int memberId;
int numberOfBooksBought;
double amountSpent;
  
memberType(string name,int id,int numberOfBooks,double amount); //parameter constructor
  
void setPersonName(string name); //member functions for personName
void modifyPersonName(string name);
string showPersonName();
  
void setNumberOfBooksBought(int numberOfBooks); //member functions for numberOfBooksBought
void modifyNumberOfBooksBought(int numberOfBooks);
int showNumberOfBooksBought();
  
void setAmoutSpent(double amount); //member functions for amountSpent
void modifyAmountSpent(double amount);
double showAmountSpent();
  
void printDetails(); //a function for printing all the details
};

memberType::memberType(string name,int id,int numberOfBooks,double amount) //constructor definition
{
personName=name;
memberId=id;
numberOfBooksBought=numberOfBooks;
amountSpent=amount;
}

void memberType::setPersonName(string name) //member function definitions
{
personName=name;
}
void memberType::modifyPersonName(string name)
{
personName=name;
}
string memberType::showPersonName()
{
return personName;
}

void memberType::setNumberOfBooksBought(int numberOfBooks)
{
numberOfBooksBought=numberOfBooks;
}
void memberType::modifyNumberOfBooksBought(int numberOfBooks)
{
numberOfBooksBought=numberOfBooks;
}
int memberType::showNumberOfBooksBought()
{
return numberOfBooksBought;
}

void memberType::setAmoutSpent(double amount)
{
amountSpent=amount;
}
void memberType::modifyAmountSpent(double amount)
{
amountSpent=amount;
}
double memberType::showAmountSpent()
{
return amountSpent;
}

void memberType::printDetails()
{
cout<<"Person Name:"<<personName<<"\nId:"<<memberId<<"\nNumber Of Books Bought:"<<numberOfBooksBought<<"\nAmount Spent:"<<amountSpent;
}

int main()
{
memberType person1("abc",101,4,1000); //creating the object of memberType as person1
cout<<"Printing the Details:\n";
person1.printDetails();
  
person1.modifyPersonName("xyz"); //modifying some detials like personname,numberofbooks,amout
person1.modifyNumberOfBooksBought(6);
person1.modifyAmountSpent(1500);
  
cout<<"\n\nModified person name:"<<person1.showPersonName()<<endl; //showing the modified data
cout<<"Modified number of books:"<<person1.showNumberOfBooksBought()<<endl;
cout<<"Modified amount spent:"<<person1.showAmountSpent()<<endl;
  
cout<<"\nPrinting the Details Again:\n";
person1.printDetails();
  
return 0;
}
