Thread: Need some help with strings

here is what I have to do

Write a program that will read in a line of text and output the number of words in the line and the number of occurrences of each letter. Define a word to be any string of letters that is delimited at each end by either whitespace, a period, a comma, or the beginning or end of the line. You can assume that the input consists entirely of letters, whitespace, commas, and periods. When outputting the number of letters that occur in a line, be sure to count upper-case and lowercase versions of a letter as the same letter. Output the letters in alphabetical order and list only those letters that do occur in the input line. For example, the input line

I say Hi.

should produce output similar to the following:

3 words
1 a
1 h
2 i
1 s
1 y



Here is what I have
Can someone help me please
I don't know what to do next

Code:

#include <iostream>
#include <cctype>

using namespace std;

void readAndCount (int &numWords, int letterCount[]);
void outputLetterCounts (int letterCount[]);

int main()
{
  int numWords;
  int letterCount[26];

  cout << endl;
  cout << "Enter a line of text.." << endl << endl;

  readAndCount (numWords, letterCount);

  cout << endl;
  cout << numWords << " words" << endl;
  outputLetterCounts(letterCount);
 
  return 0;
}

void readAndCount (int &numWords, int letterCount[])



void outputLetterCounts (int letterCount[])



void outputLetterCounts(int letterCount[])
{
  for (int i = 0; i < 26; i++)
    {
      if (letterCount[i] > 0)
     {
       cout << letterCount[i] << " " << char('a' + i) << endl;
     }
    }
}
