Fastest way to Convert String to Binary?
提问by Derp
I want to convert a string, using the string class - to Binary. What is the fast way to do this character by character. Loop? Or is there some function out there that will convert for me? 1's and 0's binary.
我想使用字符串类将字符串转换为二进制。逐个字符执行此操作的快速方法是什么。环形？或者是否有一些功能可以为我转换？1 和 0 的二进制。
A string being:
一个字符串是：
#include <string>
using namespace std;
int main(){
myString = "Hello World";
}

Using std::bitsetwould work:
使用std::bitset会起作用：
#include <string>
#include <bitset>
#include <iostream>
using namespace std;
int main(){
string myString = "Hello World";
for (std::size_t i = 0; i < myString.size(); ++i)
{
cout << bitset<8>(myString.c_str()[i]) << endl;
}
}
Output:
输出：
01001000
01100101
01101100
01101100
01101111
00100000
01010111
01101111
01110010
01101100
01100100

Try using this with method. Example:
尝试将其与方法一起使用。例子：
#include <iostream>
#include <bitset>
using namespace std;
string TextToBinaryString(string words) {
string binaryString = "";
for (char& _char : words) {
binaryString +=bitset<8>(_char).to_string();
}
return binaryString;
}
int main()
{
string testText = "Hello World";
cout << "Test text: " << testText << "!\n";
cout << "Convert text to binary: " << TextToBinaryString(testText) << "!\n";
return 0;
}
result code:
结果代码：
Test text: Hello World!
Convert text to binary: 0100100001100101011011000110110001101111001000000101011101101111011100100110110001100100!

char * buf = data.c_str; //buf is binary
char * buf = data.c_str; //buf is binary
