Help! Please

I'm trying to write a program to count the number of each letter of the alphabet and count the words. I have the word count but don't know how to start my letter counts.
thanks in advance for your help...

Here is what i have so far:

# include <iostream.h>
# include "string.h"

void alphabet( char [] ); //functions prototype

int main()
{
int count = 0;
char string[256];

cout <<"Please enter 1 line of text from the keyboard. \n";
cout <<"Please hit enter when you are done.\n\n";
cin.getline(string, 256, '\n'); //The user input goes into string
int countA = 0;
for(int i = 0; i < 256; i++)
{
if (string[i] == 'a' || 'A')
countA++;
else
}
cout <<"A " << countA << "\n";


char *tokenPtr;
tokenPtr = strtok( string, " " );

while ( tokenPtr != NULL )/* The following code counts the words or tokens in a sentence.*/
{
tokenPtr = strtok( NULL, " " );
count = count + 1;
}//end while ( tokenPtr != NULL )

cout << "Word Count: " << count;

return 0;
}//end int main ()

You could create a 26 element array 0-a 25-z, and loop through your line incremeting the [theletter-a] element for each letter.

this will get you started

Code:

#include "stdafx.h"
#include <iostream>
using namespace std;

int Occurences( char cAlpha, char* szString );

int main() 
{ 

	char szString[ 256 ];
	strcpy( szString, "THis is a very long STRING and all characters WILL BE counted" );

	char cAlpha = 'A';
	for( int i = 0; i < 26;i++ )
	{
		cout <<  cAlpha << " occurs " << Occurences( cAlpha , szString ) 
			<< " times in the string  \"" << szString << "\""<< endl;
		cAlpha++; // a + 1 = b and so on
	}

	return 0; 
} // end

int Occurences( char cAlpha, char* szString )
{
	// NULL pointer bad ju-ju
	if( NULL == szString )
	{
		return 0;
	}

	int i = 0;
	int nCount = 0;
	do
	{
		//an Uppercase character + 32 is the lowercase of the character
		//here we test for both.. more info on this look at an acii code chart
		if( cAlpha == szString[ i ] || ( cAlpha + 32 ) == szString[ i ] )
			nCount++;
		i++;
	}
	while( NULL != szString[ i ] );

	return nCount;

}

I still don't get it, i want it so the user can enter a line of text.
