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; }
