First, don't ask for help for your home work until you have tried enough. public class CreditCard { public string cardNumber{get;set;} public string clientName{get;set;} public float balance{get;set;} public float limit{get;set;} public float spend ( float amount) { if (amount { return balance+amount; } return 0; } public float pay ( float amount) { if (amount { return balance-amount; } return 0; } } public class program { public void Main() { Console.WriteLine( "Enter cardNumber for the credit Card" ); string cardNumber=Console.ReadLine(); Console.WriteLine( "Enter clientName of credit Card" ); string clientName =Console.ReadLine(); Console.WriteLine( "Enter initial balance of credit Card" ); float balance =( float )Console.ReadLine(); Console.WriteLine( "Enter credit Card limit " ); string limit =( float )Console.ReadLine(); CreditCard cc= new CreditCard() { cardNumber=cardNumber; clientName =clientName ; balance =balance ; limit =limit ; } ; Console.WriteLine( "Enter Amount to be added to credit Card " ); float amount= ( float )Console.ReadLine(); float newAmount=cc.spend(amount); if (newAmount==0) { Console.WriteLine( "amount exceeded card limit" ); } else { Console.WriteLine( "newAmount={0}" ,newAmount); } Console.WriteLine( "Enter Amount to be paid from your credit Card " ); float amount1= ( float )Console.ReadLine(); float newAmount1=cc.pay(amount); if (newAmount1==0) { Console.WriteLine( "You have insufficient balance" ); } else { Console.WriteLine( "newAmount={0}" ,newAmount1); } } }

Hi, This is the basic structure and you can write your own logic to achieve the business requirement. public class CreditCard { public string CardNumber { get ; set ; } public string ClientName { get ; set ; } public float Balance { get ; set ; } public float Limit { get ; set ; } public float Spend( float amount) { this .Balance = this .Balance + amount; return this .Balance; } public float Pay( float amount) { this .Balance = this .Balance - amount; return this .Balance; } }
