I am up to upgrade a program to make it dynamically configurable from files. What i need is a number of vector viables, and that number being dependant of int variable.
我要升级程序，使其可以从文件中动态配置。我需要的是一些矢量元素，并且该数字依赖于int变量。
int k=4 //loaded from file, i handled it
vector<string> NAME(k)
Moreover, names of those variables need to be rising numbers (first object: NAME1, second NAME2 etc.).
而且，这些变量的名称需要是上升数字（第一个对象：NAME1，第二个NAME2等）。
This is my first ever post there, so sorry for all the mistakes or lack of information :)
这是我在那里的第一篇帖子，很抱歉所有的错误或缺乏信息:)

You can't dynamically name variables, but you could store them in a map.
您无法动态命名变量，但可以将它们存储在地图中。
std::map<std::string, std::vector<std::string> > myVectors;
for (int i = 0; i < k; ++i)
{
std::ostringstream name;
name << "NAME" << i;
myVectors.insert(std::make_pair(name.str(), std::vector<std::string>()));
}

使用
vector<vector<string> > name(k);
Where do you get the names from? I from file you could map instead. Probably yes when reading again sorry. Did not solve more than part of the problem.
你从哪里得到这些名字？我从文件中你可以映射。可能是的，再次阅读对不起。没有解决超过部分问题。
