Reference(引用) vs Pointer(指针) in C++ 指针(Pointer)是C语言最复杂且强大的特性,其本质是一个整形变量(4 bytes@x86; 8 bytes@x64),里面存储的值被解释为地址。由于指针变量的值被解释为内存地址,所以它可以让程序员可以直接访问和操作内存。指针用好了,可以带来近似于汇编语言的极其高的执行效率(Best perfo...
Usingsmart pointers, we can make pointers to work in way that we don’t need to explicitly call delete.Smart pointeris a wrapper class over a pointer with operator like * and -> overloaded. Smart pointer can do many things like automatic destruction (yes, we don’t have to explicitly use...
Use *variable Notation to Pass Function Arguments by Reference in C++Similar behavior to the previous example can be implemented using pointers. Note that a pointer is an address of the object, and it can be dereferenced with the * operator to access the object value. Passing the arguments usi...
但reference是一种『高级的pointer』,不需deference即可取值,所以不论是几层,仍然是reference这个变量而已,也因为不需dereference,所以书上都强调reference可视为变量的alias(别名、化名)(C++ Primer 4th P.59 A reference
与pointer 类似,一个reference是一个对象(object),可以用来间接指向另一个对象。一个reference的声明与pointer的声明的实质语法结构是相同的。不同的是,声明pointer的时候使用星号操作符 * , 而声明reference的时候使用地址操作符 & 。 例如,我们有: int i = 3; ...
As you know, an address of an object in C++ can be stored either through a reference or through a pointer. Although it might appear that they represent similar concepts, one of the important differences is that you can reassign a pointer to point to a different address, but you cannot do...
