c++ - 在空格上有选择地拆分字符串

Question

我的命令是:

move 1 "South Africa" "Europe"

代码:

do 
{
  cut = text.find(' ');
  if (cut == string::npos) 
  {
    params.push_back(text);
  } 
  else 
  {
    params.push_back(text.substr(0, cut));
    text = text.substr(cut + 1);
  }
}  
while (cut != string::npos);

问题是 South Africa 正在 split 成 South 和 Africa，我需要它保留 South Africa.

切割后的参数:

1, South, Africa, Europe

我需要它是:

1, South Africa, Europe

我该怎么做？用正则表达式？

命令的另一个例子:

move 3 "New Island" "South Afrika"

我的代码在 ' ' 之后被截断，我需要在我推回的参数中

3, New Island, South Africa

我的代码使得:

3,"New,Island","South,Africa"

Answer 1

您可以使用 std::stringstream 和 std::getline 解析您的字符串

#include <iostream>
#include <sstream>
#include <string>

int main() {
    std::string text("move 3 \"New Island\" \"South Afrika\"");
    std::string command, count, country1, country2, temp;
    std::stringstream ss(text);

    ss >> command >> count;
    ss.str("");
    ss << text;
    std::getline(ss, temp, '\"');
    std::getline(ss, country1, '\"');
    std::getline(ss, temp, '\"');
    std::getline(ss, country2, '\"');

    std::cout << command << ", " << count << ", " <<
        country1 << ", " << country2 << std::endl;
    return 0;
}
