无法对字符串进行标记化并将其传递给c++中的结构

#include <iostream>
#include <vector>
#include <string>

// 定义C++结构
struct MyStruct {
    std::string name;
    int age;
    double salary;
};

int main() {
    std::string input = "John,25,5000.00";
    
    // 字符串标记化
    std::vector<std::string> tokens;
    std::string delimiter = ",";
    size_t pos = 0;
    std::string token;
    
    while ((pos = input.find(delimiter)) != std::string::npos) {
        token = input.substr(0, pos);
        tokens.push_back(token);
        input.erase(0, pos + delimiter.length());
    }
    tokens.push_back(input); // 添加最后一个标记
    
    // 解析标记化后的字符串并赋值给结构
    MyStruct myStruct;
    myStruct.name = tokens[0];
    myStruct.age = std::stoi(tokens[1]);
    myStruct.salary = std::stod(tokens[2]);
    
    // 使用结构
    std::cout << "Name: " << myStruct.name << std::endl;
    std::cout << "Age: " << myStruct.age << std::endl;
    std::cout << "Salary: " << myStruct.salary << std::endl;
    
    return 0;
}
