Question

I wrote some JavaScript code but now I want to translate it to C++ because of perfomance, but my knowledge of C++ is low.

In JavaScript I can do:

var arr=[[['à','á'],['è','é'],['ì','í'],['ò','ó'],['ù','ú']],['a','e','i','o','u']];

How can I do something like that in C++?
Must I do

vector<vector<char>> arr;

and then set each element manually?

arr[0][0]='à';
arr[0][1]='á';
...

Yes, it’s at least a bit more work unless you have C++11, which adds the possibility of constructors taking an initializer list:

std::vector<std::vector<char>> arr {{'a', 'b'}, {'c', 'd', 'e'}, {'f'}};

You might also consider replacing std::vector<char> with std::string.
