The __div__ magic method is used to implement division in Python. It is invoked when the / operator is used on two operands, and it returns the result of the division. 这行代码调用 __div__ 魔术方法对两个操作数执行除法。 返回除法结果。 什么是_div_ ? Python 中的 div 函数返回两个数...
你的operator=实现完全错误。当您取消引用并分配给res指针时,它不会指向任何有意义的地方。这就是你的代码崩溃的原因。 实际上,您需要自己将单个成员从obj复制到*this,这与您在构造函数中的操作类似,例如: #include <iostream>using namespace std;class STUDENT { public: string ID; string name; unsigned int...

Hello Codeforces community, A few months ago, I had noticed a fact and had written a blog on how the Double division operator should be used for floor division instead of math.floor() in Python. This is because the single division operator behaves abnormally for very large numbers in Python...
