如何从多个向量数组制作CSV文件?

问题描述

vector <string> CSVWrites;
vector <string> s1; s1[0]="A";
vector <string> s2; s2[0]="B";
vector <string> s3; s3[0]="C";
vector <string> s4; s4[0]="D";

stringstream ss;
ss << s1[0].c_str()<<","<<s2[0].c_str()<<","<<s3[0].c_str()<<","<<s4[0].c_str();

CSVWrites.push_back(ss.str());

我不知道处理这种情况的更好方法，如果有一个向量，则创建CSV文件非常容易.我有100个向量，如果按照上述方式操作，我不确定stringstream是否支持那么多.
示例每个向量数组中的两个元素
A，B，C，D
E，F，G，H
.......
.......
如果您有想法，我将非常感谢您的帮助.

I don''t know the better way to handle this case, if there is one vector, it is very easy to create an CSV file. I have 100 vectors, I am not sure stringstream supports that much if I do as above way.
Example two elements from each vector array
A,B,C,D
E,F,G,H

If you have an idea, I am greatly appreciate for your help.
