如果我在预测正确地说，您是否希望用户仅输入偶数值作为输入？


问候

If I am predicting correctly, do you want user to enter only even values as an input?

你可以使用MOD运算符检查输入是偶数还是奇数。如果是奇数，您可以决定应该采取什么行动。要么您没有对输入做任何事情，要么强制输入为偶数。

You can use the MOD operator to check if the input is even or odd. If it is odd, you can decide what action should be taken. Either you don''t do anything with the input or you force the input to an even number.
