C二維字符數組的使用及如何獲取二維數組的總行數和總列數！

#include <stdio.h>
#include <stdlib.h>
int main(){
	char str[][30] = {"zhangsan","lisi","wangwu"};
	char (*p)[30] = str; //定義行指針
	printf("%p %p %p 行數：%d 列數：%d\n",str, &str[0], &str[0][0], sizeof(str)/sizeof(str[0]),sizeof(str[0])/sizeof(str[0][0]));
	
	//行數 = sizeof(array)/sizeof(array[0]);
	//列數 = sizeof(array[0])/sizeof(array[0][0]);
	int i;
	for(i=0;i<sizeof(str)/sizeof(str[0]);i++){
		printf("%s \n",*(p+i));
	}

	
	return 0;
	
}
