如何从C++文件中读取带逗号的数字？

ifstream file("filename");

string line;
while (getline(file, line)) {
    stringstream ss(line);
    string number;
    while (getline(ss, number, ',')) {
        // 处理每个数字
    }
}

int num = stoi(number);

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

using namespace std;

int main() {
    ifstream file("filename");
    if (!file) {
        cout << "Failed to open file." << endl;
        return 1;
    }

    string line;
    while (getline(file, line)) {
        stringstream ss(line);
        string number;
        while (getline(ss, number, ',')) {
            int num = stoi(number);
            // 处理每个数字
            cout << num << endl;
        }
    }

    file.close();
    return 0;
}
