Question

Write a program to accept a two digit number and check whether it is a special number or not

Answer 1

Answer:

// CPP program to find if number is  

// a Special Two-Digit number or not

#include<bits/stdc++.h>

using namespace std;

 

// function to find if number  

// is special or not

void specialNumber(int n)

{

   // Checking whether entered

   // number is 2 digit or not

   if (n < 10 || n > 99)  

       cout << "Invalid Input! Number"

            << " should have 2 digits only";

   else

   {  

       // Finding the first digit

       int first = n / 10;

         

       // Finding the last digit

       int last = n % 10;  

         

       // Finding the sum of

       // the digits

       int sum = first + last;  

         

       // Finding the product

       // of the digits

       int pro = first * last;  

         

       if ((sum + pro) == n)

       {

           cout << n <<" is a Special "

                << "Two-Digit Number";

       }

       else

       {

           cout << n << " is Not a "

                << "Special Two-Digit Number";

       }

   }

}

 

// Driver Code

int main()

{

   int n = 59;

     

   // function calling

   specialNumber(n);

   return 0;

}
