A C example of same could look like: #include <limits.h> #include <stdio.h> const char *is_positive (int value) { return value < 0 ? "false" : "true"; } int main (int ac, char *av[]) { printf (" 1 is positive? %s\n", is_positive (1)); printf (" 2 is positive? %s\n", is_positive (2)); printf (" -1 is positive? %s\n", is_positive (-1)); printf (" -2 is positive? %s\n", is_positive (-2)); printf ("%ld is positive? %s\n", (long)INT_MAX, is_positive (INT_MAX)); printf ("%ld is positive? %s\n", (long)INT_MAX + 1L, is_positive (INT_MAX + 1)); /* this one is can be quite pernicious */ printf (" 0 is positive? %s\n", is_positive (0)); return 0; }
