写下条件-三个数字中只有一个是5的倍数

Question

There should be <=3 comparison operators and no extra parentheses. So

condition = x % 5 == 0 ^ y % 5 == 0 ^ z % 5 == 0;

Doesn't test right when X, Y and Z are both multiple of fives

Answer 1

Then I expect you want something like

condition = x % 5 == 0 ? y % 5 != 0 && z % 5 != 0 : y % 5 == 0 ^ z % 5 == 0;

Or

condition = (x % 5 == 0 ? 1 : 0 + y % 5 != 0 ? 1 : 0 + z % 5 != 0 ? 1 : 0) == 1;

Answer 2

Here is a condition:

x*y*z % 5 == 0 && (x*y + x*z + y*z + x*y*z % 5 != 0)

The first part means that any of x , y or z is a multiple of 5 (recall that 5 is a prime number!) The second part makes sure that no two of them are.
