c++ unsigned short转string

在C++中,将无符号短整型(unsigned short)转换为字符串(std::string),可以使用`std::to_string()`函数或者手动迭代无符号短整数值并逐位构建字符串。这里介绍两种常见的方式:
**方法一:使用`std::to_string()`**
```cpp
#include <iostream>
#include <string>
unsigned short usValue = 1234; // 无符号短整型值
std::string strUsValue = std::to_string(usValue);
std::cout << "Unsigned short to string: " << strUsValue << '\n';
```
**方法二:手动转换(迭代法)**
```cpp
#include <iostream>
#include <array>
unsigned short usValue = 1234;
std::string manualConversion(unsigned short value) {
std::string result;
const std::array<char, sizeof(unsigned short)*CHAR_BIT> digits{'0', '1', '2', '3', '4', '5', '6', '7', '8', '9'};
for (size_t i = 0; i < sizeof(unsigned short) * CHAR_BIT; ++i) {
result += digits[value & 0xF];
value >>= 4;
if (value == 0 && i != sizeof(unsigned short) * CHAR_BIT - 1) { // 如果还有剩余位,则添加分隔符
result += ' ';
}
}
return result;
}
int main() {
std::string strUsValue = manualConversion(usValue);
std::cout << "Unsigned short to string (manual): " << strUsValue << '\n';
}
```
以上两种方法都可以将无符号短整型转换为字符串形式。选择哪种取决于具体需求和个人偏好。
