Hello
If there is any doubt feel free to Comment, A Like would be highly appreciated.

Here is the Program in which i have created All the attributes and function required apart from that i have created one display member function to check the difference which i have commented for better understanding.

main.cpp LJ Run 1 #include <iostream> 2 class Account 3 4 5 -- 6 // Private Attributes int id; double balance; 7 8 9 public: 1 / No Argument Contructor Account() { 10 11 12 - 13 14 15 16 17 18 id=0; balance=0.0; } 1/Argument Constructor Account(int aid, double bal) { 19- 20 id=a id; balance-bal; 21 I/Getter and Setter method int get_id() Y 22 23 24 25 26 - 27 28 29 30 - return id; } double get_balance() {

{ Y- -- } { Y- ** *** 29 double get_balance() 30 - 31 return balance; 32 33 void set_id(int aid) 34 - 35 id=aid; 36 37 void set_balance(double bal) 38 - 39 balance=bal; 40 41 - /* 42 *To display Id and Balance if required** 43 44 void display() 45- 46 std::cout << id<<" has "<<balance << std::endl; 47 }*/ 48 }; 49 int main() 50 - { 1/Creating Account object with default Constructor 52 Account ac=Account(); 53- 54 //Before update 55 ac.display(); 56 57 58 17 Updating Balance 59 ac.set_balance (2000); 60 -- 51 /* */

// Updating Balance ac.set_balance(2000); /* //After update ac.display(); */ return 0;

This is the program
As per the Question they have just asked to update the balance not to check and display so no output although i made one display function if required.
In case you need to copy Code,
So here it is:

#include <iostream>

class Account
{
//Private Attributes
int id;
double balance;
  
public:
//No Argument Contructor
Account()
{
id=0;
balance=0.0;
}
  
//Argument Constructor
Account(int aid, double bal)
{
id=aid;
balance=bal;
}
  
//Getter and Setter method
int get_id()
{
return id;
}
double get_balance()
{
return balance;
}
void set_id(int aid)
{
id=aid;
}
void set_balance(double bal)
{
balance=bal;
}
/*
************To display Id and Balance if required********************
  
void display()
{
std::cout << id<<" has "<<balance << std::endl;
}*/
};
int main()
{
//Creating Account object with default Constructor
Account ac=Account();
/*
//Before update
ac.display();
*/
  
//Updating Balance
ac.set_balance(2000);
  
/*
//After update
ac.display();
*/
return 0;
}
Thanks:)
