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.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 implementation of the Bank class in C++:
#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 account_number, char operation_type, double old_balance, double amount) {
this->account_number = account_number;
this->operation_type = operation_type;
this->old_balance = old_balance;
this->amount = amount;
}
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 << "New balance: " << new_balance << endl;
}
};
int main() {
Bank b(1011, 'D', 1000, 2000);
b.calculate();
return 0;
}
In this program, we have a class Bank with private member variables for account_number, operation_type, old_balance, amount, and new_balance. The constructor of the class initializes these variables. The calculate function checks the operation_type and performs the deposit or withdrawal operation accordingly, then prints the new balance. If the operation type is invalid or there is not enough balance for withdrawal, it prints an error message. The main function creates an object of the class and calls the calculate function.
