C ++字符串为二进制code /二进制code串 [英] C++ string to binary code / binary code to string

问题描述

我需要一个字符串转换成与第一串的二进制code的字符串。
在第一部分我用这个：将字符串转换为二进制的最快方法完美工作，但我不能想出一个办法来记录到一个新的字符串。

这里的code我使用至今：

 的（为size_t我= 0; I＆LT; outputInformations.size（）; ++ I）
{
    COUT＆LT;＆LT;位集＆所述8为氢;（outputInformations.c_str（）[I]）;
}
 

输出：

<$p$p><$c$c>01110100011001010111001101110100011101010111001101100101011100100110111001100001011011010110010100001010011101000110010101110011011101000111000001100001011100110111001101110111011011110111001001100100

有没有写入到一个新的字符串这样的方法吗？所以，我呼吁一个字符串binary_outputInformations与它里面的二进制code。

解决方案

您在找这个？

 字符串的myString =Hello World的;
  标准::字符串binary_outputInformations;
  对于（的std ::为size_t我= 0; I＆LT; myString.size（）; ++ I）
  {
  位集＆所述8是氢; B（myString.c_str（）[I]）;
      binary_outputInformations + = b.to_string（）;
  }  性病::法院LT＆;＆LT; binary_outputInformations;
 

输出：

<$c$c>0100100001100101011011000110110001101111001000000101011101101111011100100110110001100100

I need to convert a string into a string with the binary code of the first string. For the first part i used this: Fastest way to Convert String to Binary? Worked perfectly but i can't figure out a way to write it into a new string.

Here's the code i'm using so far:

for (size_t i = 0; i < outputInformations.size(); ++i)
{
    cout << bitset<8>(outputInformations.c_str()[i]);
}

Output:

01110100011001010111001101110100011101010111001101100101011100100110111001100001011011010110010100001010011101000110010101110011011101000111000001100001011100110111001101110111011011110111001001100100

Is there a way to write this into a new string? So that i have a string called "binary_outputInformations" with the binary code inside it.

解决方案

Are you looking for this ?

  string myString = "Hello World";
  std::string binary_outputInformations;
  for (std::size_t i = 0; i < myString.size(); ++i)
  {
  bitset<8> b(myString.c_str()[i]);
      binary_outputInformations+= b.to_string();
  }

  std::cout<<binary_outputInformations;

Output :

0100100001100101011011000110110001101111001000000101011101101111011100100110110001100100
