Converting text to phonetic alphabet --- if loop problem..

[AndrewThe70sMan]

Hi all,

I am writing a program that converts text in a standard .txt file into the NATO phonetic alphabet ( a= alfa, b = beta, c = charlie, etc..)

I am having some trouble in the conversion stage of my program.. during my if loop, i get an error message saying "ISO C++ FORBIDS COMPARISON BETWEEN POINTER AND INTEGER" and I am not sure of a way to fix this.


here is the relevant part of my sourcefile

void readSourceFile ()
{
	ifstream myfile;
	myfile.open (filename, ios::binary );
	
	 if (myfile.is_open())
  {
  	myfile.seekg (0, ios::end);
  	length = myfile.tellg();
  	myfile.seekg (0, ios::beg);

  	buffer = new char [length];

  	myfile.read (buffer,length);
  	myfile.close();

  	cout.write (buffer,length);
  	cout << endl << endl << endl;
  	
  }
  else cout << "Unable To Open File, Try A Different Filename." << endl << endl << endl << endl;

}

void convertSourceFile ()
{
 	 ofstream myfile;
 	 myfile.open ("Convertion.txt");
 	 
 	 if (myfile.is_open())
 	 {
	    int n;
	    int i;

	    for ( n = 0, i = 0; i < (length + 1); i++, n++)
            {
			 if (buffer[n] == "A"){   //THIS IS THE IF LOOP
 			     myfile << "Alfa";
                         }
		         else if (buffer[n] == "B"){ //AND OF COURSE THESE TOO..
                             myfile << "Beta";
			 }
			 else if (buffer[n] == "C"){
 			     myfile << "Charlie";
                         }
		         else if (buffer[n] == "D"){
			     myfile << "Delta";
			 }
			 else if (buffer[n] == "E"){
 			     myfile << "Echo";
                         }
		         else if (buffer[n] == "F"){
			     myfile << "Foxtrot";
			 }
  	   }
     }
}

I know the conversion part is incomplete but I wanted to try a sample before I went ahead and wrote the entire alphabet out..


thanks in advance for and help, much appreciated.

Change double quotes for single quotes. ( if (buffer[n] == 'A') etc. )

'A' is a single character whilst "A" is a string of two characters ('A' + '\0')

ahh, of course, I knew i was just missing something simple..

program is working great now
