翻译:"请输入一个数字"

Please key in a number, I'll tell you whether it's a odd number or a even number.

输入的话，个人认为是 key in... 二楼的和四楼的别误人子弟... input 根本就不是动词，怎么可以当作谓语...

Please input a number. I can tell you if it's odd or even

在编程吗?
Please input a number ,I will tell you whether it is an odd or an even

Enter a number, I will let you know it is odd or even.

请输入一个数字,我会告诉你,这是奇数还是偶数

Please enter a number, I will tell you, this is odd or even number

please enter a number and i will tell you whether it is eve or odd.
