Question

我有以下阵列:

char* mask[9];
int hSobelMask[9] = {
    -1, -2, -1,
    0, 0, 0,
    1, 2, 1};

我想就这一阵列提出一点看法,即:

int H = applyMask(&mask, &hSobelMask);

The signature of the Application Mask function is the folowing:

int applyMask(char** mask[9], int* sobelMask[9]);

但我收到以下警告:

demo.c: In function ‘customSobel’:
demo.c:232:7: warning: passing argument 1 of ‘applyMask’ from incompatible pointer type
demo.c:181:5: note: expected ‘char ***’ but argument is of type ‘char * (*)[9]’
demo.c:232:7: warning: passing argument 2 of ‘applyMask’ from incompatible pointer type
demo.c:181:5: note: expected ‘int **’ but argument is of type ‘int (*)[9]’

这种警告意味着什么,我是如何摆脱的?

Answer 1

你们想要把点人带到这些阵列? 因此,你或许会回顾一下:

int applyMask(char* (*mask)[9], int (*sobelMask)[9]);

Answer 2

int applyMask(char** mask, int* sobelMask);

Answer 3

www.un.org/spanish/ga/president 它们不兼容。仅此更改您的职能签名:

int applyMask(char** mask, int* sobelMask)

or this:

int applyMask(char* mask[], int sobelMask[])

www.un.org/Depts/DGACM/index_spanish.htm 加入 (在沙巴兹发表以下评论后): 要求你履行以下职能:

int H = applyMask(mask, hSobelMask);

没有必要使用<代码>&,因为一个阵列的变量已经是阵列内容的参照点。
