C++ small bank program using a class

Question

I want to create a bank program in C++ that will store customer information (maybe in a text file or some sort) like:

name
account type
account number
account balance
deposit and withdraw functions
edit account
delete account
show all account.

---

Class bankAccounts
{
   private:
string customerName
char accType
int accountNo
double accBalance
   public:
bankAccounts()
~bankAccounts()
displayAccount()
depositAccount()
withdrawAccount()
deleteAccount()
showAccounts()

how would i use the constructor? maybe to set the balance and accountnum to 0. how could i do this and also how would i implement other functions?

Answer 1

Here's how. Create a Parameterized Constructor and pass the values you want to be assigned to the object as arguments.

#include <iostream>
#include <string>

class bankAccounts
{
private:
    std::string customerName;
    char accType;
    int accountNo;
    double accBalance;

public:
    bankAccounts();

    bankAccounts(std::string cn ,char act, int acno, double accB) //Parameterized constructor
    {
        customerName =cn;
        accType=act;
        accountNo=acno;
        accBalance=accB;
    }

    //Implement your functions inside/ outside the class

    // displayAccount();
    // depositAccount();
    // withdrawAccount();
    // deleteAccount();
    // showAccounts();

};


int main()
{
    std::string customerName;
    char accType;
    int accountNo;
    double accBalance;
    std::cin>>customerName>>accType>>accountNo>>accBalance;//get your data
    bankAccounts B(customerName, accType, accountNo, accBalance);
    //object B has all attributes you wanted

    //Enjoy :)

    return 0;
