C++字符串分割方法详解

#include <iostream>
#include <string>
#include <sstream>
#include <vector>
std::vector<std::string> split(const std::string& str, char delim) {
std::vector<std::string> result;
std::stringstream ss(str);
std::string item;
while (std::getline(ss, item, delim)) {
    result.push_back(item);
}

return result;
}

std::string text = "apple,banana,orange";
auto parts = split(text, ',');
for (const auto& part : parts) {
    std::cout << part << std::endl;
}

std::vector<std::string> splitString(const std::string& str, const std::string& delimiter) {
    std::vector<std::string> result;
    size_t start = 0;
    size_t end = str.find(delimiter);
while (end != std::string::npos) {
    result.push_back(str.substr(start, end - start));
    start = end + delimiter.length();
    end = str.find(delimiter, start);
}
result.push_back(str.substr(start)); // 添加最后一段
return result;
}

#include <boost/algorithm/string.hpp>
#include <vector>
#include <string>
std::string text = "one,two,three";
std::vector<std::string> result;
boost::split(result, text, boost::is_any_of(","));
