C++ 如何将printfxterm代码转换为ostringstream？

问题

我正在尝试将一些C

printf

代码转换为

std:：ostringstream

，但我在十六进制/终端编码方面遇到了问题。我想也许，序列<代码> \x1b（48；5；< /Cord>）需要同时翻译，但我不确定C++中的等价性是什么。 坏结果，部分（C++）

好结果，xterm（C）

C代码

void Color_Cube()
{
  for (unsigned green=0; green<6; ++green)
  {
    for (unsigned red=0; red<6; ++red)
    {
      for (unsigned blue=0; blue<6; ++blue)
      {
        unsigned color = 16 + (red * 36) + (green * 6) + blue;
        printf( "\x1b[48;5;%dm  ", color );
      }
      printf( "\x1b[0m " );
    }
    printf( "\n" );
  }
}

void Color_Cube_cpp()
{
  std::ostringstream  oss;
  for (unsigned green=0; green<6; ++green)
  {
    for (unsigned red=0; red<6; ++red)
    {
      for (unsigned blue=0; blue<6; ++blue)
      {
        unsigned color = 16 + (red * 36) + (green * 6) + blue;
        oss << std::hex << static_cast<int>(0x1b) << std::dec
          << "[48;5;" << color << "m  ";
      }
      oss << std::hex << static_cast<int>(0x1b) << std::dec << "[0m ";
    }
    oss << "\n";
  }
  std::cerr << oss.str() << "\n";
}

void Color\u Cube（）
{
对于（unsigned green=0；green尝试替换
std:：hex尝试替换
std:：hex您就快到了。您需要流式传输转义字符
'\x1b'
，而不是整数
0x1b
：

#include <sstream>
#include <iostream>

void Color_Cube_cpp()
{
  std::ostringstream  oss;
  for (unsigned green=0; green<6; ++green)
  {
    for (unsigned red=0; red<6; ++red)
    {
      for (unsigned blue=0; blue<6; ++blue)
      {
        unsigned color = 16 + (red * 36) + (green * 6) + blue;
          oss << "\x1b[48;5;" << color << "m  ";
      }
      oss << "\x1b[0m ";
    }
    oss << "\n";
  }
  std::cerr << oss.str() << "\n";
