Thread: What is error, kindly solve the issue and make me know my fault

I have two files
1.dfa.hpp and 2. test.cpp

1.dfa.hpp's content

Code:

#include<iostream>
using namespace std;

namespace DFASpace{
        class dfa       {
                dfa(int n)      {
                        cout << "The value of n is: " << n << endl;
                }
        };
}

2.test.cpp's content

Code:

#include "dfa.hpp"

using DFASpace;

int main(){
        dfa d = dfa(50);
        return 0;
}

Am getting errors when I compile as:

Code:

[kapil@localhost learn3]$ g++ test.cpp  
test.cpp:3: error: expected nested-name-specifier before ‘DFASpace’
test.cpp:3: error: namespace ‘DFASpace’ not allowed in using-declaration
test.cpp: In function ‘int main()’:
test.cpp:6: error: ‘dfa’ was not declared in this scope
test.cpp:6: error: expected ‘;’ before ‘d’

I dont think a namespace is defined in such way!
for your words, I include ; yet its not working!

if you are talking about test.cpp then ; is there,
kindly make the necessary changes on the code which you feel is not correct, may be I am unable to spot what you are talking about!

You're missing the keyword namespace.

Sorry to say that Salem is very confusing, thnks to ctrl_freak
