// example: 数组形参(p193)
/*
* 定义若干print函数,功能是打印数组内容,稍微做了微调
*/
#include <iostream>
using std::cout;

// 使用标记指定数组长度
void print(const char *cp)
{

while (*cp) // 只要指针所指字符非空字符
cout << *cp++; // 输出当前字符并将指针向前移动一个位置
}
// 使用标准库规范
void print(const int *beg, const int *end)

// 输出beg到end之间(不含end)的所有元素
while (beg != end)

// const int ia[]等价于const int* ia
