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

#include <iostream>

using namespace std;

int main() {

   int n,c=0;

   cout<<"Enter a number: ";

   cin>>n;

   while(n!=0){

       c++;

       n/=10;

   }

   if(c==1)

       cout<<"Its a single digit number.";

   else if(c==2)

       cout<<"Its a double digit number.";

   else

       cout<<"Its a multi digit number.";

   return 0;

}

• Here, we have asked the user to enter a number.
• The while loop counts the number of digits present in the number and store it in variable - 'c'.
• After termination of while loop, if the value of c is '1', then a message is displayed that - "Number is single digit.".
• If the value of c is 2, "Number is double digit" or else, it is "Multi Digit".
