system("color 0b");
char admin[100]="abc";
char secret[100]="123";
char nadmin[100]={0};
char nsecret[100]={0};

printf("\n");
printf("\n");
printf("\n");
printf("\n");
printf("\n");
printf("\n");
printf(" 请输入密码:");
gets(nsecret);
system("cls");
}while(strcmp(admin,nadmin)!=0||strcmp(secret,nsecret)!=0);
system("cls");
printf("\n");
printf("\n");
printf("\n");printf("\n");
