It is obvious that the following code is invalid

    int strnum = 0;
    string token [strnum]; //Tokens storage;
    while(token[strnum] != "END"){


First of all the size of an array shall be a const expression according to the C++ Standard. Secondly your array has zero size. Thirdly you are trying to use uninitialized element of the array. So all this three statements are invalid.
