        幹點事...

        常見的技巧越來越多了哦...
        有興趣的可以鑽研看看.

E1)     # include <stdio.h>

        # define min(x, y)      ((x) < (y) ? (x) : (y))

        int main()
        {
            int a, b, c;

                puts("Enter 3 integers.");
                if (scanf("%d%d%d", &a, &b, &c) < 3)
                        exit(1);

                printf("The minimum is %d.\n", min(a, min(b, c)));

            return 0;
        }

E2)     # include <stdio.h>
        # include <string.h>

        # define PASSWORD       "1234567"

        int main()
        {
            char        s[80 + 1];
            int         i;

                for (i = 0; i < 3; i++) {
                        puts("\n[Authorization codes]");
                        fgets(s, sizeof s, stdin);
                        *strchr(s, '\n') = '\0';

                        if (!strcmp(s, PASSWORD))       {
                                puts("*** Welcome! ***");
                                break;
                        } else
                                puts("--- Password mismatch.");
                }

            return 0;
        }

E3)     # include <stdio.h>
        # include <stdlib.h>
        # include <time.h>

        int main()
        {
            int n, k;

                srand(time(NULL));
                n = rand();
                printf("DEBUG! n %d\n", n);

                do      {
                        puts("\n*** Guess it!");

                        if (scanf("%d", &k) < 1)
                                exit(1);
                        else if (n == k)        {
                                printf("-> X == %d.\n", k);
                                break;
                        }

                        printf("### X %c %d\n", n < k ? '<' : '>', k);
                } while (k != n);

            return 0;
        }
