發問:
我呢排學緊C++ 我知道cout <<17%5會出2 點解(-17)%5出-2 點解17%(-5)出2 詳細解一下,THX!!!
最佳解答:
The C++ standard requires that (a/b)*b + a%b == a, we can rearrange this to a%b == a-(a/b)*b. And that explains everything.5.6/4 [...] if the quotient a/b is representable in the type of the result, (a/b)*b + a%b is equal to a.
