使用C++读取具有两个连续分隔符的csv文件

#include <fstream>
#include <iostream>

int main() {
    std::ifstream file("data.csv");
    if (!file.is_open()) {
        std::cout << "Failed to open the CSV file." << std::endl;
        return 1;
    }

    // 读取CSV文件的代码

    file.close();
    return 0;
}

std::string line;
while (std::getline(file, line)) {
    // 处理每一行的代码
}

std::string field;
std::stringstream ss(line);
while (std::getline(ss, field, ',')) {
    // 处理每个字段的代码
}

std::string field;
std::stringstream ss(line);
while (std::getline(ss, field, ',')) {
    // 处理每个字段的代码
    if (field.empty()) {
        field = ",";
    }
}

#include <fstream>
#include <iostream>
#include <sstream>

int main() {
    std::ifstream file("data.csv");
    if (!file.is_open()) {
        std::cout << "Failed to open the CSV file." << std::endl;
        return 1;
    }

    std::string line;
    while (std::getline(file, line)) {
        std::string field;
        std::stringstream ss(line);
        while (std::getline(ss, field, ',')) {
            if (field.empty()) {
                field = ",";
            }
            // 处理每个字段的代码
            std::cout << field << std::endl;
        }
    }

    file.close();
    return 0;
}
