Sorry, I guess that was it in the first comment.

There are a couple obvious problems in your "case 1" for creating a new account. You don't check the value of i, so you'll get an error if you try to add an account if i >= 10. Also, you increment the value of i first, so you have an account a[0] which you never use.

In your newaccount() method, you increment the instance member accno (which may or may not be initialized to zero -- if it is, then your accno will always be 1, otherwise it will be some arbitrary value), and ignore your static class-member (which I think you intended to provide successive new account numbers).

Your transfermoney() method also has problems -- first of all, you add the money to the destination account before you determine whether the source account has sufficient funds. Also, instead of copying the destination account into the method, and then copying back via assignment, consider passing a pointer to the destination account, and modifying it directly as needed in the method.

In case 5, where did the "b" variable come from?
