C语言中关于指针，二维数组等的问题，一个有趣的发现

刚刚重新学习C语言的字符数组，发现了一个小问题，放在这里供大家讨论一下

Code:

#include <stdio.h>

#include <stdlib.h>



const char *testcase[30] = {"jo","vicent","tom","honey","gigi","lily","susan","peter","bob","ron",

"jason","henry","kiki","ken","auscar","vivian","yiyi","peace","iron","lotus"

"andy","arta","ophone","denial","pipe","wade","james","kobe","kent","angel"};





//Function Definition

void countSort(char *source[30]);



//Function Implementation

void countSort(char *source[30]){





}



//Main Function

void main(){



//countSort(testcase);

printf ("*testcase=%x/n",*testcase);

printf ("testcase=%x/n",testcase);

printf ("&testcase=%x/n",&testcase);



int i=3;

int *pt = &i;

int **ppt = &pt;

printf ("pt=%x/n",pt);

printf ("&pt=%x/n",&pt);

printf ("ppt=%x/n",ppt);

printf ("&ppt=%x/n",&ppt);

}



很简单的一段代码，运行结果放一下：

*testcase=42103c

testcase=4232f8

&testcase=4232f8

pt=12ff44

&pt=12ff40

ppt=12ff40

&ppt=12ff3c

我在这里只有一个问题：为什么testcase这个二维指针的地址：&testcase跟testcase里面的的内容：4232f8是一样的呢？

请各位指教。
