Vectors of Objects_Lab 13 Solution

– Lab 13–Vectors of Objects

Goals:

·         Understand how to build and use Classes

·         Understand how to use vectors of objects built with classes

Development Environment: (all students must use Clion)

Skills:Classes, Default Constructor, Constructor, member functions, vectors of objects.

Reading: Chap 13

Deliverables:1) This lab with2screen shots2) lastnameFirstLab12.cpp, Scores.h, Scores.cpp

 

Part I – Skills Practice (10 points)

·         Open a new project in CLion.  Call the project Lab13a. 

·         For this project will make vectors of objects and use the built in member functions to add, and erase records.

New-New C++ Class


Add the name Bank.  And accept the defaults Add to targets and Lab11a<-$(Source_Files)
This will create both a Bank.h file and a Bank.cpp file
Double Click on the Bank.h file. Replace the entire text with this
#ifndefBANK_H
#define BANK_H

#include <string
#include <iostream
using namespace std;
class Bank
{
private:
string name;
intnumber;
float balance;
public:
    Bank();
    Bank(string _name, int_number, float _balance);
string getName(){return name;}
void setName(string _name){name=_name;}
intgetNumber() {return number;}
void setNumber(int_number){number = _number;}
float getBalance(){return balance;}
void increaseBalance(float amount);

};
#endif

 

·         Now double click on the Bank.cpp.  Replace the entire code with the code below:

#include "Bank.h"
Bank::Bank()
{
name = "";
number = 0;
balance = 0;
}

Bank::Bank(string _name, int_number, float _balance)
{
name = _name;
number = _number;
balance = _balance;
}

void Bank::increaseBalance(float amount)
{
balance = balance + amount;
}

 

New-New C++ class.  Call it functions

·         In functions.h

#ifndefFUNCTIONS_H

#define FUNCTIONS_H

#include "Bank.h"

#include <vector

void bubbleSort(vector<Bank&acctVector);

ostream&operator << (ostream&out, Bank &tempBank);

#endif
 

·         In functions.cpp

·         Now double click on the main.cpp.  Replace the entire code with the code below:

#include "functions.h"
void bubbleSort(vector<Bank&acctVector)
{
//Bubble Sort records by name
intmaxElement;
intindex;
Bank tempBank3;

for (maxElement = acctVector.size() - 1; maxElement0; maxElement--)
    {
for (index = 0; index <maxElement; index++)
        {
if (acctVector[index].getName() acctVector[index + 1].getName())
            {
//swap the entire record (name, number, balance)
tempBank3 = acctVector[index];
acctVector[index] = acctVector[index + 1];
acctVector[index + 1] = tempBank3;
            }//if
}//for
}//for
}

ostream&operator << (ostream&out, Bank &tempBank)
{
cout<<tempBank.getName() <<endl;
cout<<tempBank.getNumber()<<endl;
cout<<tempBank.getBalance()<<endl<<endl;
return out;
}

 

·         In main.cpp

#include <iostream
#include <vector
#include "Bank.h"
#include "functions.h"
using namespace std;
intmain()
{
string tempName;
inttempNumber, size;
float tempBalance;
Bank tempBank;

vector<BankacctVector;
cout<<"How many records do you want to add?\n";
cinsize;
cin.ignore();
for (inti=0; i<size; i++)
    {
cout<<"Name for customer " <<i+1 <<endl;
getline(cin,tempName);
cout<<"Number for customer " <<i+1 <<endl;
cintempNumber;
cout<<"Balance for customer " <<i+1 <<endl;
cintempBalance;
cin.ignore(); //removes '/n' in buffer for next getline
cout<<endl;
tempBank.setName(tempName);
tempBank.setNumber(tempNumber);
tempBank.increaseBalance(tempBalance);
acctVector.push_back(tempBank);
    }

bubbleSort(acctVector);

for (inti=0;i<acctVector.size(); i++)
    {
cout<<acctVector[i]<<endl;
    }

return 0;

 

·         Now if you did everything correctly it should compile. If it has errors, try to fix the errors by reading the error and clicking on the link to the error.

·         Once it successfully compiles, go to Run-Run Lab 13a (Note the Clion terminal window repeats all input from the user, so don’t worry about trying to fix that)
