C/C++读写csv文件

csv文件其实就是文本文件，每行字段用逗号分隔。

代码

#include 
#include 
#include 
#include 
#include 

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> 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 lineArray;
		// 按照逗号分隔
		while (getline(ss, str, ','))
			lineArray.push_back(str);
		strArray.push_back(lineArray);
	}
	
	getchar();
	return 0;
}

结果
