声明动态多维指针 [英] Declaring dynamic Multi-Dimensional pointer

问题描述

是否可以在运行时声明N维指针?例如，如果[N = 2，** p]，[N = 3，*** p]，[N = 4，**** p]，依此类推.如果是这样，怎么办?

Is it possible to declare a N-Dimension pointer during runtime? like, if [N = 2, **p], [N = 3, ***p], [N = 4, ****p] , and so on. If so, how ?

推荐答案

可能不是您想要的，但是您可以定义常规的 void * 指针，然后根据 N .

Possibly, it's not what you want, but you can define general void * pointer and then cast them depending on the N.

丑陋的例子:

void *genericPtr;
if (1 == N) {
    int *ptr = (int *)genericPtr;
    // your code here
} else if (2 == N) {
    int **ptr = (int **)genericPtr;
    // your code here
}
