Finally, other nonwhitespace characters in
scanf calls must match
corresponding characters in the input; otherwise, reading stops. Two
percent signs are a special case; they must match a single percent sign in
int i, j; scanf ("%i%% %i%%", &i, &j); printf ("The total percentage is %i.\n", i + j); --- Data --- 4% 16% --- Result --- The total percentage is 20.
