C++ 读写CSV文件，注意一下格式即可

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

using namespace std;  

int main()
{
    // 写文件
    ofstream outFile;
    outFile.open("data.csv", ios::out); // 打开模式可省略
    outFile << "name" << ‘,‘ << "age" << ‘,‘ << "hobby" << endl;
    outFile << "Mike" << ‘,‘ << 18 << ‘,‘ << "paiting" << endl;
    outFile << "Tom" << ‘,‘ << 25 << ‘,‘ << "football" << endl;
    outFile << "Jack" << ‘,‘ << 21 << ‘,‘ << "music" << endl;
    outFile.close();  

    // 读文件
    ifstream inFile("data.csv", ios::in);
    string lineStr;
    vector<vector<string>> strArray;
    while (getline(inFile, lineStr))
    {
        // 打印整行字符串
        cout << lineStr << endl;
        // 存成二维表结构
        stringstream ss(lineStr);
        string str;
        vector<string> lineArray;
        // 按照逗号分隔
        while (getline(ss, str, ‘,‘))
            lineArray.push_back(str);
        strArray.push_back(lineArray);
    }  

    getchar();
    return 0;
} 

输出
