C++ – 阿拉伯数字字符串转换为中文读法的中文字符串，支持小数点
1 C++阿拉伯数字字符串转换为中文读法的中文字符串，不支持小数点
最近碰到一个这样的需求，就是将阿拉伯数字字符串转换为中文读法的中文字符串，形如将
"199922"
转换为：
"十九万九千九百二十二"
经过一番折腾，已经可以成功完成转换，并支持个位数到兆的范围转换，我的示例代码如下：
#include <iostream>
#include <string>
std::wstring ConvertNumToChineseNum(const std::wstring& num)
{
std::wstring chinaeseNumResult;
std::wstring num_copy = num;
int size = num_copy.length();
for (int i = 0; i < num_copy.size(); ++i)
{
if (num_copy[i] == L'1')
{
chinaeseNumResult += L"一";
}
else if (num_copy[i] == L'2')
{
chinaeseNumResult += L"二";
}
else if (num_copy[i] == L'3')
{
chinaeseNumResult += L"三";
}
else if (num_copy[i] == L'4')
{
chinaeseNumResult += L"四";
}
else if (num_copy[i] == L'5')
{
chinaeseNumResult += L"五";
}
else if (num_copy[i] == L'6')
{
chinaeseNumResult += L"六";
}
else if (num_copy[i] == L'7')
{
chinaeseNumResult += L"七";
}
else if (num_copy[i] == L'8')
{
chinaeseNumResult += L"八";
}
else if (num_copy[i] == L'9')
{
chinaeseNumResult += L"九";
}
if (num_copy[i] == L'0')
{
if (size % 4 == 3)
{
if (num_copy[i + 1] != L'0' || num_copy[i + 2] != L'0')
{
chinaeseNumResult += L"零";
}
}
else if (size % 4 == 2 && num_copy[i - 1] != L'0')
{
if (num_copy[i + 1] != L'0')
{
chinaeseNumResult += L"零";
}
}
}
if (size % 4 == 1)
{
if (size / 4 == 1)
{
if (num_copy[i] != L'0' || num_copy[i - 1] != L'0' || num_copy[i - 2] != L'0' || num_copy[i - 3] != L'0')
{
chinaeseNumResult += L"万";
}
}
else if (size / 4 == 2)
{
if (num_copy[i] != L'0' || num_copy[i - 1] != L'0' || num_copy[i - 2] != L'0' || num_copy[i - 3] != L'0')
{
chinaeseNumResult += L"亿";
}
}
if (size / 4 == 3)
{
if (num_copy[i] != L'0' || num_copy[i - 1] != L'0' || num_copy[i - 2] != L'0' || num_copy[i - 3] != L'0')
{
chinaeseNumResult += L"兆";
}
}
}
if (num_copy[i] != L'0')
{
if (size % 4 == 2)
{
chinaeseNumResult += L"十";
}
if (size % 4 == 3)
{
chinaeseNumResult += L"百";
}
if (size % 4 == 0)
{
chinaeseNumResult += L"千";
}
}
--size;
}
return chinaeseNumResult;
}
int main()
{
std::wstring result = ConvertNumToChineseNum(L"352717183921");
std::wcout << result << std::endl;
return 0;
}
运行结果如下：

形如将
"199922.99"
转换为：
"十九万九千九百二十二点九九"
