Here’s a step-by-step explanation of the code:
1. Headers, Namespace, and Class:
- Same as the previous code, defining the BankAccount class.
2. Main Function:
- int main(): The program’s entry point.
- int n; Declares an integer variable n to store the number of account holders.
- cout << “Enter the number of account holders: “; cin >> n; Prompts the user to enter the number of accounts and stores it in n.
- BankAccount accounts[n]; Creates an array named accounts to hold n objects of the BankAccount class.
3. Getting Account Details:
- for (int i = 0; i < n; i++) { … }: Iterates n times to get details for each account holder.
- string name; int accountNo; float initialBalance; Declares variables to store account details.
- cout << “\nEnter details for account holder ” << i + 1 << “:\n”; Prompts for details.
- cin >> name; cin >> accountNo; cin >> initialBalance; Reads input from the user.
- accounts[i].initialize(name, accountNo, initialBalance); Initializes the i-th account object in the accounts array with the provided details.
4. Performing Transactions and Displaying Details:
- for (int i = 0; i < n; i++) { … }: Iterates through each account object in the array.
- accounts[i].deposit(1000); accounts[i].withdraw(500); Performs example transactions (deposit and withdrawal) on each account.
- cout << “\nAccount ” << i + 1 << ” details:\n”; accounts[i].display(); Prints account details for each account.
5. Return Statement:
- return 0; Indicates successful program termination.
