Employing %s in scanf with out an explcit discipline width opens a similar buffer overflow exploit that gets did; namely, if there are far more people in the input stream than the goal buffer is sized to hold, scanf will happily create All those extra characters to memory exterior the buffer, potentially clobbering some thing significant.
