Is it possible to declare two variables For-in Loop in C++?

I am trying to write a function which can check, If a string has all characters with the same frequency. So in order to do that, I tried to make two Maps i.e unordered_map<char, int>. So in my next step, I just want to compare each value of each char on my map.

for(char i : B && char i : B){              //code goes here          }

So, Is it possible to have a For-In loop with two different variable like that?
