In the following example, a pointer to a 2D array is passed as a parameter, where the second dimension is specified: Code: #include <stdio.h> void test(int (*N)[4]) { int i, j; printf("\n\nPrint the matrix within the test function:"); for(i = 0 ; i < 4 ; i++) { p...

在许多 C 程序中,指针常被用于引用数组,或者作为数组的元素。指向数组的指针常被简称为数组指针(array pointer),而具有指针类型元素的数组则被称为指针数组(pointer array)。 数组指针 为了便于举例,下面的描述均以一个 int 数组为例。同样的原理可以应用于其他类型数组,包括多维数组。

Double pointers are instrumental in dynamically allocating memory for 2D arrays. This is because a 2D array can be thought of as an array of pointers, where each pointer corresponds to a row in the array. Declaring, Allocating, and Freeing 2D Arrays To dynamically create a 2D array, you fir...
An array name is not a pointer. Although an array name can be treated as a pointer at times, and array notation can be used with pointers, they are distinct and cannot always be used in place of each other. Understanding this difference will help you avoid incorrect use of these ...
