Error: no match for call to (std::vector<char>) (int&)

One Pea (49)
I get this error inside all of the for loops for the multiArrayCipher function.

does this help?

multiArrayTwo[counter]=sentance[j];

you did this all over. Most of the time vectors are accessed with [] not (); the only common use of () is to reserve space
vector <char> hassize(1000); //() used to get space
hassize[3] = 'x'; //[] used to access, though.

multiArrayOne(counter) is a function call.

multiArrayOne[counter] accesses an element of the vector.
