I am having a problem with passing pointers to a class.

I have a class called stack that works fine but when I try to pass a pointer
to an instance

of the class it gives me problems.

I need to know how to get to the methods of the object when I get it to the
function and

perhaps how to pass it.


this is the sending function,

below it is a snipit of the recieving function.

#include "scj_arr.h"
#include "stack.h"
#include "ass_out.h"
#include<iostream.h>
#include<stdlib.h>
#include<ctype.h>
#include<fstream.h>
#define MAX 50
// Function Prototypes
int file_to_stack(stack *my_stack1, stack *my_stack2);
int order_stack(stack *my_stack1, stack *my_stack2);
void init_array(const char init_val, char array[], int arr_size);
int process_command();
int check_op(char c);
file://int out_to_file(stack my_stack1, stack my_stack2);



void main()
{
 int test=0;
 int quit=0;
 static stack my_stack1;
 static stack my_stack2;
 stack *ptr_to_stack1;
 stack *ptr_to_stack2;

 ptr_to_stack1 = &my_stack1;
 ptr_to_stack2 = &my_stack2;


 int finished = 0;
 cout << "\nAssembly Compiler Program\n";
 while (!quit)
 {
  test = file_to_stack(ptr_to_stack1, ptr_to_stack2);//stack 2 is corrected
  test = order_stack(ptr_to_stack1, ptr_to_stack2); file://stack 1 is
corrected
  test = out_to_file(ptr_to_stack1, ptr_to_stack2); file://use stack 1


 cout << endl;
 cout << endl;
 my_stack1.st_clear();
 cout << "All Done? 1=YES 0=NO \n";
 cin >> quit;
 }
}


file://here is one of the recieving functions
int file_to_stack(stack *my_stack1, stack *my_stack2)
{
 char c;
 char c1;
 int count2=0;
 int count3=0;
 int pass_fail = 0;
 FILE *stream;
 int numread;
 char item;
 char element[MAX];
 char temp_element[MAX];
 char temp_element2[MAX];
 char filename_in[80];
 int count = 0;
 int count1 = 0;

 init_array(NULL, element, MAX);
 init_array(NULL, temp_element, MAX);
 init_array(NULL, temp_element2, MAX);

 cout << "What is the name of the file you want to open?";
 cout << endl;
 cin >> filename_in;
 stream=fopen(filename_in, "rb");// open for read binary



 do /*create a stack of arrays of equations*/
 {
  numread = fread(&item, sizeof(char),1,stream);
  if ((isalnum(item)) || (ispunct(item)) && (isprint(item)))
  {
   element[count] = item;
   ++count;
  if ((item==';') && (isprint(item)) && (item>0))
  {
   strcpy(temp_element,element);

   for (count2=0; count2<count; count2++)
   {
    c = element[count2];
    c1 = element[count2+1];
    temp_element[count3]=c;
    temp_element2[0]=c1;
    ++count3;

    if (check_op(c1))
    {
     my_stack1.st_put( temp_element );
     my_stack1.st_put( temp_element2 );
     init_array(NULL, temp_element, MAX);
     init_array(NULL, temp_element2, MAX);
     count3 = 0;
     count2++;
    }
   }
   cout << element;
   cout << "\n";
   init_array(NULL, element, MAX);
   count = 0;
   item = NULL;
  }
  }
 } while (numread>0);

 cout << endl;
 my_stack1.st_dump();
 fclose(stream);





return pass_fail;
}

I get this sort of error "left of .st_put requires class/struct/union type"
I understand

that I have only the pointer to the stack in the function but I cannot seem
to dereferance

the pointer. I would appreciate any help.
