I must read a file with a given name (it's caled "hamlet.txt"). The class used to read the file is defined like this

#ifndef READWORDS_H
#define READWORDS_H
/**
 * ReadWords class. Provides mechanisms to read a text file, and return
 * capitalized words from that file.
 */
using namespace std;

#include <string>
#include <fstream>

 class ReadWords
 {
   public:
    /**
     * Constructor. Opens the file with the default name "text.txt".
     * Program exits with an error message if the file does not exist.
     */
     ReadWords();

    /**
     * Constructor. Opens the file with the given filename.
     * Program exits with an error message if the file does not exist.
     * @param filename - a C string naming the file to read.
     */
     ReadWords(char *filename);

My definition of the members of the classis this:

#include<string>
#include<fstream>
#include<iostream>
#include "ReadWords.h"

using namespace std;

ReadWords::ReadWords()
{
    wordfile.open("text.txt");
    if( !wordfile )
    {
        cout<<"Errors while opening the file!"<<endl;
    }
}

ReadWords::ReadWords(char *filename)
{
    wordfile.open(filename);

    if ( !wordfile )
    {
        cout<<"Errors while opening the file!"<<endl;
    }

    wordfile>>nextword;
}

And the main to test it. using namespace std; #include #include

#include "ReadWords.h"



int main()
{
   char name[30];
   cout<<"Please input a name for the file that you wish to open";
   cin>>name;
   ReadWords x( name[] );
}

When I complie it gives me the error: main.cpp:14: error: expected primary-expression before ']' token

I know it's got something to do with the function ReadWords( char *filename), but I do not know what. Any help please?
