1067 试密码（C语言）

设计思路：

• 依旧考察如何正确处理输入

编译器：C (gcc)

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

int main()
{
        int n;
        char password[21], try[21], c;

        scanf("%s %d", password, &n);
        while (getchar() != '\n')
                continue;

        while (n--) {
                scanf("%20[^\n]", try);
                c = ungetc(getchar(), stdin);
                if (!strcmp(try, "#") && c == '\n') {
                        break;
                } else if (!strcmp(password, try) && c == '\n') {
                        puts("Welcome in");
                        break;
                } else {
                        printf("Wrong password: %s", try);
                        while (putchar(getchar()) != '\n')
                                continue;
                        if (!n)
                                puts("Account locked");
                }
        }

        return 0;
}
