Stroring file text into array

I am attempting to write a program that inputs lines of text from a file.  The program then displays the total occurrences of each letter, including the apostrophe.  I am having trouble storing the letters into an array.

#include <iostream>
using std::cin;
using std::cout;
using std::endl;
using std::iostream;
using std::ostream;

#include <string>
using std::getline;

#include<iomanip>
using std::setw;

#include <cstring>
using std::string;

#include <fstream>
using std::fstream;
using std::ifstream;
using std::ofstream;

//Prototype
int readData( char *, char *, int [ ]);

//constant
const char apostrophe = '\'';

int main( )
{
                     // get the total number of EACH LETTER
      int letterTotals[ 28 ] = { 0 };
      int numberOfWords;
      char *wordArrayPtr = { 0 };
      numberOfWords = readData( myInFilePtr, wordArrayPtr, letterTotals );

                     return 0;

} // end of main

int readData( char *fileNamePtr, char *wWordArrayPtr, int letterTotals[ ] )
{
      int wordCount = 1;
      char currentLetter;
      ifstream wMyInFile( fileNamePtr );
      int letterIndex = 0;
      
      wWordArrayPtr = new char;
      //int counter = 0;

      while( !wMyInFile.eof() )
      {
            currentLetter = wMyInFile.peek();      // look at first letter
            //tolower( currentLetter );
            
            cout << " ----> Press Enter to add letter totals of next word to current totals.\n\n";
            getchar();      // used to stop the program before each word

            while( isalpha( currentLetter ) || ( currentLetter == apostrophe ) )
            {      
                  // increment the appropriate index of letterTotals array
                  if (currentLetter >= 'A' && currentLetter <= 'Z')
                  {
                        letterTotals[ int(currentLetter - 'A') + 1 ]++;
                  }
                  else if (currentLetter >='a' && currentLetter <= 'z')
                  {
                        letterTotals[ int(currentLetter - 'a') + 1 ]++;
                  }
                  else if (currentLetter == '\'')
                  {
                        letterTotals[0]++;
                  }
                  //letterTotals[ wordCount ] += wMyInFile.get();
                  //letterTotals[ counter ];
                  cout << "\n\n ---> current letter = " << currentLetter << "\n\n";                  
                  wWordArrayPtr[ wordCount ] += wMyInFile.get( );      // store letter in array
                  currentLetter = wMyInFile.peek();      // look at the next char      

                  /*
                  char letterValue = 96;
                  cout << "letter: " << letterValue << "     ";
                  int index = 0;
                  cout << "letterTotals[ " << index << " ] = " << letterTotals[ index ] << "\n";
                  letterValue = 65;
                  
                  for( index = 1; index < 27; index++ )

                  */      
            }
            
            //counter++;

            //letterIndex = 0;
            cout << "\n wordCount before letterTotals = " << wordCount << "\n\n";

            char letterValue = 96;

            int index = 0;

                  letterValue++;
            }

            cout << "\n wordCount after letterTotals = " << wordCount << "\n\n";
            
            // !!! -----> the following while is an infinite loop without the break

            //currentLetter = wMyInFile.peek();      // look at the next char
            wordCount++;
            wWordArrayPtr = new char;
      }
      //cout << "\n Is it reaching this point?\n";
      return wordCount;

} // end of readData
