Assignment
Problem Statement:
In this assignment you will be modeling a part of simple banking system. In this system, there are two classes, Customer and Account which are related to each other via aggregation relationship.
Account class has the following data members:
- Account No.
- Current Balance
- Bank name
- Branch code
Account class must have the following member functions:
Function
|
Description
|
Account()
|
Default constructor for account class, setting account balance to 0, Account number to 1, branch name to NULL and branch code to 0
|
Account(float, int, char *, int)
|
It will take balance, account no, bank name and branch code as arguments and set their values accordingly
|
withdraw(float)
|
This will subtract amount from the balance of account that will be passed as its parameter.
If the amount being withdrawn is greater the balance of the account , it will display the message “Insufficient balance”
|
deposit(float)
|
Function will add amount to the balance of account. Amount will be passed as its parameter.
|
getBalance()
|
This function will return the value of available balance
|
getAccountNo()
|
This function will return the account number
|
getBankName()
|
This function will return the name of bank
|
getBrachCode()
|
This function will return branch code of bank
|
Customer class has the following data members:
- Customer Name
- Address
- Account object
Customer class must have the following member functions:
Function
|
Description
|
display()
|
This function will display the values of all data members of Customer and Account class
|
Parameterized constructor
|
It will take Account, name and address as a arguments and set their values accordingly
|
Within main() function, objects of both classes will be created , and respective member functions of these objects will be called.
First of all create an object of Account class by passing balance, account number, bank name and branch code. Then create an object of customer class by passing Account object, name and address. Now call display() function which will display all the values of Customer including his/her name, address and account detail.
The program should prompt the user to enter a value and call deposit() function passing it entered value. Then call the display() function.
After this, the program should prompt the user to enter a value and call withdraw() function passing it entered value. Then call the display() function.
Sample output of the program:
BEST OF LUCK!
Solution
#include <iostream.h>
using namespace std;
// Account Class Declaration and Definition
class account{
private:
int accountNo;
float balance;
string bankName;
int b_code;
public:
account(){ // Default Constructor
accountNo=00;
balance=0.0;
bankName="Default";
b_code=00;
} // End of Default Constructor
account(int ac_num, float bal, string b_name, int code){ // Parametarized Constructor
accountNo=ac_num;
balance=bal;
bankName=b_name;
b_code= code;
} // End Parametarized Constructor
void withdraw(float draw_money){ // WithDrawl Func
if (balance<draw_money){
cout "\n\a \"Insufficient balance.......\"";
}
else{
balance-=draw_money;
}
} // End of WithDrawl Func
void deposit(float add_money){ // Deposit Func
balance+=add_money;
}
// And other some self explanatory Function of Account Class
float getBalance(){
return balance;
}
int getAccountNo(){
return accountNo;
}
string getBankName(){
return bankName;
}
int getBrachCode(){
return b_code;
}
}; // End of Account Class
class customer{
private:
string name;
string address;
public:
account ac; // public because it is represented as public in class diagram
customer(string n, string a, account acc){ // Parametarized Constructor
name= n;
address=a;
ac=acc;
} // End of Parametarized Constructor
void display(){
cout "\n Customer Name: "name;
cout "\n Customer Address: "address;
cout "\n Bank Name: "ac.getBankName();
cout "\n Branch Code: "ac.getBrachCode();
cout "\n Current Balance: "ac.getBalance();
cout "\n Account No. "ac.getAccountNo();
}
}; // End of Customer Class
main(){
cout "..........Displaying Customer Account Information........."endlendl;
account myaccount(7812, 40000, "Askari Bank", 123); // Creating an account Obj
customer DD("Double Diamond", "Programming Island", myaccount); // Creating an customer Obj
DD.display();
float dep, draw;
cout "\n\n Please Enter a value for Deposit: ";
cin >> dep;
DD.ac.deposit(dep);
cout "\n\n Current Balance after Depositing...";
DD.display();
cout "\n\n Please Enter a value for Withdrawl: ";
cin >> draw;
DD.ac.withdraw(draw);
cout "\n\n Current Balance after withdrawing...";
DD.display();
cout endlendl;
system("pause");
