- c - Using the scanf () function - Stack Overflow
Using scanf and printf when you're confused about types is dangerous! scanf ("%s", userinput); The type of userinput is char (*)[256], but scanf expects %s to correspond to a char * Since the type expected and the type given differ and aren't required to have the same representation, the behaviour is undefined
- What are scanf(%*s) and scanf(%*d) format identifiers?
