其中p就是一个指针变量。如果C语言中仅仅存在这类指针,那显然指针不会形成“大患”。经常地我们会在代码中看到下面的情形: int **q = &p; int ***z = &q; 随着符号'*'个数的增加,C代码的理解复杂度似乎也曾指数级别增长似的。像q、z这样的指向指针的指针(pointer to pointer to …)变量,中文俗称“...
C languageTwo-dimensional arrayAddressPointerIn C language, it is difficult to use the pointer to access the two-dimensional array element. The reason is the addresses of two-dimensional array are many, pointers that can access the two-dimensional array element are many and complex. This paper ...
This article demonstrates how to determine the size of a pointer using the C programming language. ADVERTISEMENT Pointers in C Programming Language A variable known as a pointer is one whose value is the address of another variable; in other words, the pointer itself contains the direct address ...
