The given problem is solved using language - C++.

#include <iostream>

using namespace std;

int main() {

   int n,i;

   cout<<"Enter a number: ";

   cin>>n;

   cout<<"\nGiven Number: "<<n<<endl;

   int arr[]={0,0,0,0,0,0,0,0,0,0};

   for(;n!=0;n/=10)

       arr[n%10]++;

   for(i=0;i<10;i++){

       if(arr[i]!=0)

           cout<<"Frequency of "<<i<<" is: "<<arr[i]<<endl;

   }

   return 0;

}

• The array stores the frequency of every digit (0-9).
• The frequency of every digit present in the number is display using loop.
