Question

1. Request a 3-digit integer from the console. Use division and modulo operations to extract each digit in reverse order. For each digit, determine if it is a factor of the original integer. Example Output (input in bold italics)

Enter a 3-digit integer: 543

Is 3 a factor of 543? 1

Is 4 a factor of 543? 0

Is 5 a factor of 543? 0

c++ language

Answer 1

The code for the above program is given below, I have commented in line for the explanation.

Code;-

#include<iostream>
using namespace std;

int main() {
int n;
cout<<"Enter the 3-digit integer: ";
cin>>n;// input the number
  
int temp=n; // store the number in temp for further use
  
// as we need only 3 digit number therefore loop only 3 times
for(int i=0;i<3;i++)
{
int r=n%10;// this will find remainder when divided by 10
cout<<"Is "<<r<<" a factor of "<<temp<<"?";
if(temp%r==0)
cout<<" 1"<<endl;
else
cout<<" 0"<<endl;
  
n=(n-r)/10;// this will reduce the digit by one like 543 -> 54
}

}

Output:-

Hope it clears your doubt and you like it :)
