Print to file issue

After going through this numerous times and making changes, I can't seem to figure out why this is not printing to the ofstream file.

Code:

---



  #include <iostream>
  #include <fstream>
  #include <string>
  #include <ctype.h>
  #define TRUE 1
  #define FALSE 0
  using namespace std;



      typedef enum
      /* book keeping tokens */
      { ENDFILE, ERROR,
      /* reserved words */
      IF, THEN, ELSE, END, REPEAT, UNTIL, READ, WRITE,
      /* multicharacter tokens */
      ID, NUM,
      /* special symbols */
      ASSIGN, EQ, LT, PLUS, MINUS, TIMES, OVER, LPAREN, RPAREN, SEMI,
      /* Output */
      OUTPUT
      } TokenType;




 /* print function */
void printToken( TokenType token, char arg[], ofstream &outfile)
{

switch ( token )
{
  case IF:      cout << "reserved word IF: " << arg << endl; break;
  case THEN:    cout << "reserved word THEN: " << arg << endl; break;
  case ELSE:    cout << "reserved word ELSE: " << arg << endl; break;
  case END:    cout << "reserved word END: " << arg << endl; break;

  case READ:    cout << "reserved word READ: " << arg << endl; break;
  case WRITE:  cout << "reserved word WRITE: " << arg << endl; break;
  case ASSIGN:  cout << ":=\n"; break;
  case LT:      cout << "<\n"; break;
  case EQ:      cout << "=\n"; break;
  case LPAREN:  cout << "(\n"; break;
  case RPAREN:  cout << ")\n"; break;
  case SEMI:    cout << ";\n"; break;
  case PLUS:    cout << "+\n"; break;
  case MINUS:  cout << "-\n"; break;
  case TIMES:  cout << "*\n"; break;
  case OVER:    cout << "/\n"; break;
  case ENDFILE: cout << "EOF\n"; break;
  case NUM:    cout << "NUM, val= " << arg << endl; break;
  case ID:      cout << "ID, name= " << arg << endl; break;
  case OUTPUT:  cout << arg << endl; break;
  case ERROR:  cout << "ERROR: \n"; break;

  default:      cout << "Unknown token: \n" << token;


}
}

Any ideas are welcomed,
thanks.

> case IF: cout << "reserved word IF: " << arg << endl; break;
You're writing to cout. Change it to outfile:

Code:

---

  case IF:      outfile << "reserved word IF: " << arg << endl; break;

---

And if you want to write to both, you could call printToken twice, first passing it wfile as the ofstream and second passing it cout. You may have to change it to an ostream though, I'm not sure.

The devil's in the details, should have seen that! thanks a bunch..
