How do I Scanf a string?

An array “decays” into a pointer to its first element, so scanf(“%s”, string) is equivalent to scanf(“%s”, &string[0]) . On the other hand, scanf(“%s”, &string) passes a pointer-to- char[256] , but it points to the same place. Then scanf , when processing the tail of its argument list, will try to pull out a char * .
