本文介绍了一个C++程序，用于将给定的整数（最多9位）转换为对应的中文读法。程序能够正确处理负数及零的情况，例如将-123456789读作“FuyiYierQiansanBaisiShiwuWanliuQianqiBaibaShijiu”。文章提供了一个示例代码，展示了如何实现这一功能。

1082. Read Number in Chinese (25)

Given an integer with no more than 9 digits, you are supposed to read it in the traditional Chinese way. Output “Fu” first if it is negative. For example, -123456789 is read as “Fu yi Yi er Qian san Bai si Shi wu Wan liu Qian qi Bai ba Shi jiu”. Note: zero (“ling”) must be handled correctly according to the Chinese tradition. For example, 100800 is “yi Shi Wan ling ba Bai”.
Input Specification:
Each input file contains one test case, which gives an integer with no more than 9 digits.
Output Specification:
For each test case, print in a line the Chinese way of reading the number. The characters are separated by a space and there must be no extra space at the end of the line.
Sample Input 1:
-123456789
Sample Output 1:
Fu yi Yi er Qian san Bai si Shi wu Wan liu Qian qi Bai ba Shi jiu
Sample Input 2:
100800
Sample Output 2:
yi Shi Wan ling ba Bai

思路：从右往左进行4个数字进行一次划分，并控制输出，对0 "ling"进行特殊判断
