Pictorial Presentation:

Sample Solution:

C++ Code :

#include <iostream>
#include <cmath>
using namespace std;
int main() 
{
 cout << "\n\n Find the first 15 Narcissistic decimal numbers: \n";
 cout << " -----------------------------------------------------\n";
  cout << " The first 15 Narcissistic decimal numbers are: \n";
    int i,ctr,j,orn,n,m,sum;
    orn=1;
    for (i=1;i<=15;)
    {
    ctr=0;
    sum=0;
    n=orn;
       while(n>0) 
       {
          n=n/10;
           ctr++;
       }
        n=orn;
       while(n>0) 
       {
          m=n % 10;
          sum=sum+pow(m,ctr);
          n=n/10;
       }
       if(sum==orn)
       {
           cout<<orn<<" ";
        i++;
       }
    orn++;
    }
	cout<<endl;
}

Sample Output:

Find the first 15 narcissistic decimal numbers:                                                     
 -----------------------------------------------------                                               
 The first 15 narcissistic decimal numbers are:
