Yes, and no, sir, you missed the point. The procedure here is to allocate then give away, not reading a fixed-length returned value.
Say you can only afford to have ten bytes in the stack. You allocate char s[10]; then give it to a library to parse something. Also telling it to abort if it’s going to be longer than ten bytes, of course.
char c; scanf("%c", &c);Great example.
Wouldn’t
getchar()be more appropriate here? Last time I used C it was 16 years ago.Yes, and no, sir, you missed the point. The procedure here is to allocate then give away, not reading a fixed-length returned value.
