[英]How to do the vector of sets in C++?
I can do a simple array of sets: set < char > * words = new set < char > [10]
How I can do a vector of sets? 我可以做一个简单的集合数组:
set < char > * words = new set < char > [10]
我如何做一组集合? This results in a compiler error: vector < set< char >> v
. 这会导致编译器错误:
vector < set< char >> v
。 Thank you for answers! 谢谢你的回答!
If vector < set< char >> v
is exactly what you've got there (I hope you cut and pasted), you've run into one of the annoying little features of C++. 如果
vector < set< char >> v
正是你所拥有的(我希望你剪切和粘贴),你会遇到一个令人烦恼的C ++小功能。

看起来像两个模板的两个闭合尖括号。 They look like a right shift operator to the compiler. 它们看起来像编译器的右移运算符。 Change them to

with a space in between. 将它们更改为

,中间有一个空格。
Fortunately, this is being addressed in the C++ standard that should be ratified this year. 幸运的是,这应该在今年应该批准的C ++标准中得到解决。 Unfortunately, you aren't working with a C++11-compliant compiler just now.
不幸的是,您刚才没有使用符合C ++ 11的编译器。
而不是'>>'尝试'>>'...就像这样:
vector<set<char> > testVect;
