Can somebody help me fix my code? it doens't work Its suppose to ..

Asks the user to enter his/her name AND validates it

Once the name is validated, then the program prompts the user to enter anything (s)he wants until user types -1.

The program must create a text file with the users name AND store EVERYTHING the user types in it.

The program must then read the contents of the file and count the number of even digits and the number of odd digits

The program should display the number of even digits if there are any; otherwise it should indicate that there are no even digits.

The program should display the number of odd digits if there are any; otherwise it should indicate that there are no odd digits.

If anyone can help fix mine please reply, This is for C++ #include
