Is it legal (and moral) for a member function to say delete this? 答案:t.cn/E4Wfcfl 合法,但: 必须保证 this 对象是通过 new(不是 new[]、不是 placement new、不是栈上、不是全局、不是其他对象成员)分配的 必须保证调用 delete this 的成员函数是最后一个调用 this 的成员函数 必须保证成员函数...

使用:int* const p = function7(); static 作用 修饰普通变量,修改变量的存储区域和生命周期,使变量存储在静态区,在 main 函数运行前就分配了空间,如果有初始值就用初始值初始化它,如果没有初始值系统用默认值初始化它。 修饰普通函数,表明函数的作用范围,仅在定义该函数的文件内才能使用。在多人开发项目时,...
