C++ Exercises: Check whether a number is a Duck Number or not

C++ Numbers: Exercise-26 with Solution

Write a program in C++ to check whether a number is a Duck Number or not.

Pictorial Presentation:

Sample Solution:

C++ Code :

# include <bits/stdc++.h>
using namespace std;

int main()
{
    int dno,dkno,r,flg;
	flg=0;
 cout << "\n\n Check whether a number is a Duck Number or not: \n";
 cout << " ----------------------------------------------------\n";
 cout << " Input a number: ";
 cin >> dkno;
 dno=dkno;
    while(dkno>0)
        {
            if(dkno % 10 == 0)
            {
            flg=1;
            break;
            }
			dkno/=10;
        }
            if(dno>0 && flg==1)
            {
            cout << " The given number is a Duck Number."<<endl;
            }
            else
            {
            cout << " The given number is not a Duck Number."<<endl;
            }
}

Sample Output:

Check whether a number is a Duck Number or not:                       
 ----------------------------------------------------                  
 Input a number: 30                                                    
 The given number is a Duck Number.
