const char name[] = "J.P.Briggs"; const char* ptrToName = name; 1. 2. 3. 这里,一个const char* 指针ptrToname用const char[13]的数组*name来初始化。这些类型(cosnt char和 const char[13])不一样,但是由于array-to-point的退化规则,代码可以编译。 但是,当把数组传值(by-value)传入函数时...
copy()函数是Python中的一个内置函数,用于创建一个对象的浅拷贝。浅拷贝是指创建一个新的对象,但是该对象的元素仍然是原始对象的引用。换句话说,浅拷贝只复制了对象的引用,而不是对象本身。 copy()函数的语法如下: 代码语言:txt 复制 new_object = copy.copy(old_object) ...
