Is string [] not a type?

The user sent a response saying:

So, take Hashthe link

void topWords(Hash const& t, std::string const& word, std::string* topA);

Besides,

  • string[] not a type in C ++
  • ...

The original function sent by the questionnaire looks like this:

void topWords(Hash t, string word, string topA[]);

I know that in Java the syntax for declaring an array is:

int[] anArray;

whereas in C ++ this is:

int anArray[someNumber];

I suspect this refers to the defendant, but perhaps they meant something else. So I consulted with n3337 :
