链接:C/C++ Pointers vs Java References - GeeksforGeeks Java 没有指针;Java 有引用。 引用:引用是指向其他事物的变量,可用作其他事物的别名。 指针:指针是存储内存地址的变量,目的是作为存储在该地址的内容的别名。 因此,指针就是引用,但引用不一定就是指针。指针是引用概念的一种特殊实现方式,而且这个术语往往...
Notes on Pointers Pointers are one of the things that make C stand out from other programming languages, like Python and Java. They are important in C, because they allow us to manipulate the data in the computer's memory. This can reduce the code and improve the performance. If you are...

Array of Pointers In C, a pointer array is a collection of indexed pointer variables of similar data types which references to a memory location. It is used when we want to refer to multiple memory locations of a similar data type. The data can be accessed by dereferencing the pointer that...
Referencing and Dereferencing PointersA pointer references a location in memory. Obtaining the value stored at that location is known as dereferencing the pointer.In C, it is important to understand the purpose of the following two operators in the context of pointer mechanism −...
C - Pointers and functions: The C language makes extensive use of pointers, as we have seen. Pointers can also be used to create references to functions. In other words, a function pointer is a variable that contains the address of a function.

在除了首尾两端的其他地方插入和删除元素,都将会导致指向deque元素的任何pointers、references、iterators失效。不过,deque的内存重分配优于vector,因为其内部结构显示不需要复制所有元素。 deque的内存区块不再被使用时,会被释放,deque的内存大小是可缩减的。不过,是不是这么做以及怎么做由实际操作版本定义。
