cpp创建csv格式文件完整代码

以下是CPP语言创建CSV文件的完整代码范例：

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main() {
    ofstream outputFile;
    outputFile.open("example.csv");
    // write the column headers
    outputFile << "Name" << "," << "Age" << "," << "Score" << endl;
    // write the data
    outputFile << "John Smith" << "," << "25" << "," << "90.5" << endl;
    outputFile << "Jane Doe" << "," << "30" << "," << "85.0" << endl;
    outputFile << "Tom Lee" << "," << "20" << "," << "92.3" << endl;
    // close the file
    outputFile.close();
    cout << "CSV file created successfully." << endl;
    return 0;
}

这个程序使用了文件流（fstream）对象创建了一个example.csv文件，并在其中写入了一些测试数据。在这个例子中，我们首先输出了CSV文件的列标题，然后按行写入了数据。注意，每个字段都用逗号分隔。当我们完成后，我们关闭文件流并输出一条消息表示程序成功地创建了CSV文件。
