In C language,/is a division and int is an integer, so if data with decimals is stored, the decimals will be automatically removed.

So 10/3 and so on. three

In C language,% is the remainder, so 10%3 is the remainder of 10 to 3, so it is equal to 1.

But for this problem, in the brackets after Z, Z can only assign values to the following x/y, and x%y only runs without assigning values, so the result output is 3.
