C++将数组写入CSV文件，简单记录

1. 正文

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

void test666()
{
    
    
	cout << "我是测试程序:" << endl;

	int arr[3][5] = {
    
    
		{
    
     1,0,1,0,1 },
		{
    
     1,1,1,0,1 },
		{
    
     0,0,0,0,1 }
	};

	int all = sizeof(arr)/sizeof(int);
	cout << "数组元素总数为："<<all << endl;
	int column = sizeof(arr[0]) / sizeof(arr[0][0]);
	int row = all / column;
	
	cout << "数组的行：" << row << endl;
	cout << "数组的列：" << column << endl;


	ofstream outFile; // 创建流对象
	outFile.open("test.csv", ios::out); // 打开文件
	for (int i = 0; i < row; i++)
	{
    
    	
		for (int j = 0; j < column; j++)
		{
    
    
			outFile << arr[i][j]<<',' ;
		}
		outFile << endl;
	}
	outFile.close(); // 关闭文件

}
