problem with a c++ program

Hello! I have a problem with a c++ program. It's about to find the unique values in an array and to copy the in another array and also to count how many times each value is met in the first array. I would be very appreciated if you help me

Code:

---

#include<iostream>
using namespace std;
void main()
{
  int a[5];
  int b[5];
  int p;
  int i;
  for (p=0; p<5; p++){
    cout<<"Enter the numbers ";
    cin>>a[p];
  }
  int flag=1;
  int temp;
  int j;
  for(i = 0; (i <5) && flag; i++)
    {
          flag = 0;
          for (j=0; j < 4; j++)
        {
              if (a[j+1] < a[j])
          {
                    temp = a[j];           
                    a[j] = a[j+1];
                    a[j+1] = temp;
                    flag = 1;
                          }
      }
  }
  int br=0;
  for(p=1;p<5;p++)
  {
          if(a[p]==a[p-1])
          {
                  br++;
          }
  }
 
  b[0]=a[0];
  int d,m=1;
  for(d=1;d<5;d++)
  {
          if(a[d]!=a[d-1])
          {
                  b[m]=a[d];
                  m++;
          }
  }
 
         
  cout<<"The numbers are"<<b[0];
  for(i=1;i<m;i++)
          cout<<b[i];
  cout<<"The number is: "<<br;


}

My problem is how to count how many times each value is met.

How would you do it? Say you were in Vegas playing blackjack and you wanted to know how many aces had gone by in the current deck. How would you do so?

You need to do the same thing here; the catch is you need to know what the possible values the original array could have, so you know what you're looking for.
