what is the problem in ATM machine program
- by Have alook
in this prigramm when the account number is uncorrect it should display a message to write a gain but when i wrote a gain by corrrect account number always it diplay the result of first account
also there is aproblem in PIN number ,the use have only three time to try if he enter wrong numbe and if enter three times wrong it should stop the program but it complete to the last part I dont know why
pleas help me
this is my proram
