Hi;About, C4716 Error: Must return a value

dedeler (7)
hi i have a homework the question is

(Account Class) Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member of type int to represent the account balance. [Note: In subsequent chapters, we’ll use numbers that contain decimal points (e.g., 2.75)—called floating-point values— to represent dollar amounts.] Provide a constructor that receives an initial balance and uses it to initialize the data member. The constructor should validate the initial balance to ensure that it’s greater than or equal to 0. If not, set the balance to 0 and display an error message indicating that the initial balance was invalid. Provide three member functions. Member function credit should add an amount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amount does not exceed the Account’s balance. If it does, the balance should be left unchanged and the function should print a message indicating "Debit amount exceeded account balance." Member function getBalance should return the current balance. Create a program that creates two Account objects and tests the member functions of class Account.

int Account::debitBalance( int debitAmount )
{
  if (debitAmount > balance)
     printf( "Your balance is not enough\n");    
  else
   { 
      balance = balance - debitAmount;
  }
 
}
 
int Account::creditBalance( int creditAmount )
{
  balance += creditAmount;
}
These functions indicate that they return an int, but no return statement is present.

I fixed it but i have a problem with if statement could u help me with that?

What is your problem? You don't need to ask permission to ask for help ;)
dedeler (7)
you see on test file line 86 selection 3 does not working when i comple the file
LB (13399)
What about it is not working? How do you know?
dedeler (7)
it says"run-time check failure#3-the variable "accountNumber" is being used without being initialized." but i did it 16. line
LB (13399)
On line 16 you declare that it exists, but you do not give it any value.
