The function symbol() does not expect any paramter. on line 21/22 you pass T.s[i] to that function, which is not correct.

after fixing this, same error. i need my void to detect of the certain word from words array has even number of letters

I don't know what s is but i would think it is an array of strings. Then T.s[i] is passing just a single string while now symboliai(string word[]) expects an array.

But you do not need to pass s at alll since symboliai(...) as a part of the class knows s. Hence you just need to pass the index:

            for(int j=0; j< s word[i].size(); j++){
                a=0;
                while(isalpha(s word[i][j])){
                    j++;
                    a++;

                }//cout<<i+1<<"      "<<a<<endl;
            }
         }
     return a;
     }


};
void lyginiai(Tekstas T){
         for(int i=0; i<=T.n; i++){
                //cout<<i<<endl;
      if(T.symboliai(i T.s[i]) %2==0){
        cout << T.s[i] << " " << T.symboliai(i T.s[i]) << endl;
      }
    }}


By the way: Neither line 5 nor 7 seems to be correct.
