C++ problems while reading a file

[System_Error]

Hey people, I have a problem. My assignment was to add on to the previously coded class that counts the numbers of words and digits so that it would count the number of numbers:

#include <fstream>
#include <iostream>
#include <iomanip>
#include <cctype>

using namespace std;

enum Features {UPPER, LOWER, DIGIT, IGNORE, EOW, EOS, NUMBER};

// Function prototypes
void OpenFiles(ifstream&, ofstream&);
void getNumberCount(int&, ifstream&);
Features Decode(char character);
void ProcessCharacter(char, int&, int&, int&, int&, int&, int&);
void PrintTable(ofstream& table, int, int, int, int, int, int, int);

int main()
{
    // Prepare files for reading and writing
    ifstream text;
    ofstream table;
    OpenFiles(text, table);
    char character;                 // Input character	
  
    // Declare and initialize counters
    int uppercaseCounter = 0;
    int lowercaseCounter = 0;
    int digitCounter = 0;
    int wordCounter = 0;
    int sentenceCounter = 0;
    int ignoreCounter = 0;
    int numberCounter = 0;
    text.get(character);  
    do
    { // Process each character
        ProcessCharacter(character, uppercaseCounter, 
            lowercaseCounter, digitCounter, sentenceCounter,
            wordCounter, ignoreCounter);
        text.get(character);          // Input one character  
    } while (text);                                              
    getNumberCount(numberCounter, text);
    PrintTable(table, uppercaseCounter, lowercaseCounter,
        digitCounter, sentenceCounter, wordCounter, ignoreCounter, numberCounter);
  text.close();
  table.close();
  
  return 0;
}

              break;
            }
         }
      }
   }
}

The problem is here:

int main()
{
    // Prepare files for reading and writing
    ifstream text;
    ofstream table;
    OpenFiles(text, table);
    char character;                 // Input character	
  
    // Declare and initialize counters
    int uppercaseCounter = 0;
    int lowercaseCounter = 0;
    int digitCounter = 0;
    int wordCounter = 0;
    int sentenceCounter = 0;
    int ignoreCounter = 0;
    int numberCounter = 0;
    text.get(character);  
    do
    { // Process each character
        ProcessCharacter(character, uppercaseCounter, 
            lowercaseCounter, digitCounter, sentenceCounter,
            wordCounter, ignoreCounter);
        text.get(character);          // Input one character  
    } while (text);                                              
    getNumberCount(numberCounter, text);
  
  return 0;
}

If I call the getNumberCount after the do while statement, then I don't get anything. If I call it before the do-while statement, I get the correct number of numbers, but then it goes crazy when it gets to the do-while and the results are really skewed. It actually shows the number of sentences and words is -1#j. Does anyone know why I'm having this problem? If you read from a file once, then can you not read correctly again?
