C ++比较两个数组并显示重复项 - Code现在可以正常工作

At last, here is the code that works:

#include <iostream>
#include <iomanip>
#include <string>
#include <algorithm>
#include <Windows.h>

using namespace std;

bool checkBuffer( char buffArray[], int buffSize );
void parseBuffer( char alphaArray[], char buffArray[], int alphaSize, int buffSize );

int main() 
{
   char alphabetArray[]= "abcdefghijklmnopqrstuvwxyz";
   char buffer[11];

   cout << "Enter the string up to 10 letters." << endl;
   cin.get(buffer, strlen(buffer) );

   checkBuffer(buffer, sizeof(buffer) );
   parseBuffer( alphabetArray, buffer, sizeof(alphabetArray), sizeof(buffer) );

   system("Pause");
   return 0;
}
bool checkBuffer( char buffArray[], int buffSize )
  {
    if(buffArray, strlen(buffArray) == 0)
      {
        cout << "The buffer is empty.  The program will end in 3 seconds. "  << endl;
        Sleep(3000);
        exit(1);
      }
} 
void parseBuffer( char alphaArray[], char buffArray[], int sizeOne, int sizeTwo )
{
   int countFreq = 0;
   for(int i = 0; i < strlen(alphaArray); i++ )
    {
       countFreq = 0; 

   for(int j = 0; j < strlen(buffArray); j++)
     {    
         if( alphaArray[i] == buffArray[j] )
         countFreq = countFreq + 1;
     }
         cout << "The letter " << alphaArray[i] << "  matched " << countFreq 
         << "    times." << endl; 
     }
}
