C二维字符数组的使用及如何获取二维数组的总行数和总列数！

#include <stdio.h>
#include <stdlib.h>
int main(){
	char str[][30] = {"zhangsan","lisi","wangwu"};
	char (*p)[30] = str; //定义行指针
	printf("%p %p %p 行数：%d 列数：%d\n",str, &str[0], &str[0][0], sizeof(str)/sizeof(str[0]),sizeof(str[0])/sizeof(str[0][0]));
 
	//行数 = sizeof(array)/sizeof(array[0]);
	//列数 = 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;
 
}
