After using scanf(), the "\n" is left in stdin, so getchar() does nothing. That's the cause of your infinite loop, I think.

If 4 valid entries aren't entered it goes into the else loop which should clear the entire input buffer since it loops around until it reaches a '\n' so I don't see how '\n' would be getting left in the system and causing problems.Originally Posted by User Name:
the problem is - you do not know if scanf left something in the input buffer...
I would think the fgets/sscanf version should be more stable
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

Do you know how to correct eh fgets/sscanf code I put in the top post to get it work correctly ?
