sizeof(type_name);//sizeof(类型);sizeof(object);//或sizeof object 都属于 sizeof对象; 所以: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 int i;sizeof(i);//合理sizeof i;//合理sizeof(int);//合理sizeof int;//不合理 对类型使用sizeof时,sizeof type_name是非法的,必须写为sizeof...
cout<<sizeof*f2<<endl; // *f2,和f2()等价,因为可以看作object,所以括号不是必要的。被认为是double 结论:对函数使用sizeof,在编译阶段会被函数返回值的类型取代, 4、指针问题 考虑下面问题: cout<<sizeof(string*)<<endl; // 4 cout<<sizeof(int*)<<endl; // 4 ...
