Description
输入一个整数a，输出以下分类显示:
(1) a小于10，printf("%d is less than 10.\n"a );
(2) a是2位数，printf("%d is 10 to 100.\n"a );
(3) a是3位数，printf("%d is 100 to 1000.\n"a );
(4) a是4位数，printf("%d is greater than 1000.\n"a );
例如，输入456 则显示: 456 is 100 to 1000.
(1) a小于10，printf("%d is less than 10.\n"a );
(2) a是2位数，printf("%d is 10 to 100.\n"a );
(3) a是3位数，printf("%d is 100 to 1000.\n"a );
(4) a是4位数，printf("%d is greater than 1000.\n"a );
例如，输入456 则显示: 456 is 100 to 1000.
