Pleae help!!! Homework woes!

Mar 30th, 2005
This is my very first introduction to C++ and I am stuck with a very simple mini-calculator project. I cannot figure out what the errors are that the compiler is showing. I have shown my written code and the compiler messages below that. I am receiving syntax errors on the 'outfile' lines where I was asked to format the output. I would appreciate any help given. Thank you, thank you!!!

C++ Syntax (Toggle Plain Text) 
  1. //Description: Create a mini calculator program that will allow user to enter 
  2. //two integers [Operand 1 and Operand 2]; program will calculate sum, 
  3. //difference, whole number quotient, remainder, real number quotient, square 
  4. //root of Operand 1, and value of Operand 2 raised to the power of 4.
  5.  
  6. //**********Preprocessor Directives**********
  7. #include <fstream>
  8. #include <iostream>
  9. #include <stdio.h>
  10. #include <iomanip>
  11. #include <cmath>
  12. #include <math.h>
  13. #include <string>
  14. using namespace std;
  15.  
  16. //**********main**********
  17. int main(void)
  18. {
  19.  
  20. int          choice,            //output choice
  21.              op1,               //Operand 1
  22.              op2,               //Operand 2
  23.              sum,               //op1 + op2
  24.              difference,        //op1 – op2
  25.              product,           //op1 * op2
  26.              w_quotient,        //op1/op2
  27.              modulus,           //op1 % op2
  28.              power;             //power
  29.  
  30. long double  r_quotient;        //op1/op2
