Hệ thống quản lý ngân hàng bằng C++

banking obj[6];

Here banking is class name and obj[] is an array type object of this class.

So this means that we can create 6 customer account or less here

Here is the program,

#include<iostream> 
#include<stdio> //gets() and puts()
#include<stdlib> //exit()
using namespace std;
class banking
{
  // by default member are private
   int amount,ac_number;
   char cust_name[20],ac_type;
 public:
 // member are public
   void get_record();
   friend void show_record(banking); // displaying customer record
   int re_amount();  // to return spacific customer amount
   int re_account(); // to return spacific customer account
   int deposit();    // deposit into account
   int withdraw();   // withdraw from account
};
 // storing data from user
    void banking::get_record()
      {
	 cout<<"Enter Account No: ";
	 cin>>ac_number;
	 cout<<"Enter the Name: ";
	 gets(cust_name);
	 cout<<"Enter the Account type(CS): ";
	 cin>>ac_type;
	 cout<<"Enter the Amount: ";
	 cin>>amount;
      }
     // return amount a specific customer
     int banking::re_amount()
     {
      return(amount);
     }
// using friend function to displaying customer record so not need to :: operator for defination
    void show_record(banking obj)
    {
       // obj can access private member of same class
       cout<<"Account No : "<<obj.ac_number<<"n";
       cout<<"Name : ";puts(obj.cust_name);
       cout<<"Account Type : "<<obj.ac_type<<"n";
       cout<<"Amount : "<<obj.amount<<"n";
    }
   // return account a customer
   int banking::re_account()
   {
      return(ac_number);
   }
  int banking::deposit()
  {
     int d;
     cout<<"Enter the ammount to be deposit: ";
     cin>>d;
     amount = amount+d;
     return amount;    // return total depsit in account
  }
  int banking::withdraw()
  {
