I have a code to reverse a sentence. It compiles fine but I get an error when I build. This is the code

#include <string>
#include <iostream>

using namespace std;


/**
   Reverse a sentence.
*/
class Sentence
{
public:
   /**
	  Creates a Sentence object.
	  @param aPhrase a sentence to reverse.
   */
   Sentence(string aPhrase);
   
   /**
	  Reverses this sentence.
	  @return the reversed sentence
   */
   string reverse();
	 
private:
   string phrase;
};

Sentence::Sentence(string aPhrase)   
{
   phrase = aPhrase;
}

  
string Sentence::reverse()
{
   if (phrase != "")
   {
	  string c = phrase.substr(0, 1);
	  string rest = phrase.substr(1, phrase.length() - 1);
	  Sentence tailSentence(rest);
	  phrase = tailSentence.reverse() + c;
   }
   return phrase;
}

int main()
{
   Sentence greeting("Hello!");
   cout << greeting.reverse() << "\n";
   return 0;
}

This is the error

I'm not sure what this means.

Check out your compiler.

Your codes is working just fine to me. I am using C++ Borland 5.5

Under the build tab, try cleaning and/or rebuilding your project.

I tryed the clean and it didn't work. I can't change the compiler because the one I am using was specified by my instructor. Is there some sort of add on I need to add. We had to add a graphics feature but I didn't see the ccc_win_proc, ccc_win_main in the list for the Horstmann graphics.

I just compiled and ran that code with Visual Studio 2008. Try making a new project and copying the code into it.

Based on the error message you made a Win32 project, but then wrote a console program. i.e. you're missing WinProc()
