这是一个编译错误，其含意是：在字符 ‘(’ 之前，应该是一个构造函数、析构函数或是类型转换等标识。编译程序现在在'('之前缺少必要的标识符，故提示错误。给你一个例子：int *p;p = new (10); // 这一句就会出现你问题中的错误。正确的写法应该是：p = new int(10);C++是一种面向对象的...
Alternatively, try moving the constructor and destructor code into new functions, and add calls to these functions from the constructor and destructor for the union. C++ Copy #include <stdio.h> struct S { void Create() { printf("Creating S.\n"); } void Destroy() { printf("Destroying ...
