Write a C++ program to implement a class called Bank that has private member variables for account_number, operation_type,old_balance , amount, and new_balance.Create a parameterized constructor to initialize the data members.Include member function “calculate “that prints the balance after deposit or withdrawal.Sample output1011 (account number)D (D-deposit / W-withdraw)1000 (old balance)2000 (amount)Sample Output3000
Solution
Sure, here is a simple C++ program that implements a Bank class as per your requirements:
#include<iostream>
#include<string>
using namespace std;
class Bank {
private:
int account_number;
char operation_type;
double old_balance;
double amount;
double new_balance;
public:
Bank(int acc_no, char op_type, double old_bal, double amt) {
account_number = acc_no;
operation_type = op_type;
old_balance = old_bal;
amount = amt;
}
void calculate() {
if(operation_type == 'D' || operation_type == 'd') {
new_balance = old_balance + amount;
} else if(operation_type == 'W' || operation_type == 'w') {
if(old_balance >= amount) {
new_balance = old_balance - amount;
} else {
cout << "Insufficient balance." << endl;
return;
}
} else {
cout << "Invalid operation type." << endl;
return;
}
cout << "Account Number: " << account_number << endl;
cout << "Operation Type: " << operation_type << endl;
cout << "Old Balance: " << old_balance << endl;
cout << "Amount: " << amount << endl;
cout << "New Balance: " << new_balance << endl;
}
};
int main() {
Bank b1(1011, 'D', 1000, 2000);
b1.calculate();
return 0;
}
This program creates a Bank class with private member variables for account_number, operation_type, old_balance, amount, and new_balance. It has a parameterized constructor to initialize these data members. The member function "calculate" checks the operation type and performs the deposit or withdrawal operation accordingly, then prints the new balance. If the operation type is invalid or if there is an attempt to withdraw more than the available balance, it prints an error message.
