      //Let the number be 123
      a=number/100;//1
      a1=number%100;//23
      b=a1/10;//2
      b1=a1%10;//3
      cout<<"The reverse of the entered number is "<<b1<<b<<a;
      getch();
      return 0;
      
}

And of course that will work for 3, 4, 6, 10 digit numbers?

And it's not a separate function.

Freddy: There is a much simpler way to solve the problem - you don't need to count digits, and you don't need to have more than one variable besides the original number.
