Question

Can someone tell me how can I fix this program?
It's supposed to tell the user if the number he/she entered is polydivisible or not.
#include <iostream> #include <cmath> using namespace std; int main () { int a; int i=10, j=0, x=1;
cout << "Please enter a number "; cin >> a;
do { j++; a= a/10; }
while (a>0);
{ i= pow(10, j-1);
}
while (a%i==0)
{
while (a%j==0) {
j--; a=a/10; i= pow(10, j-2);
} }
cout << "The number is polydivisible" << endl; }
cout << "The number is not polydivisible" << endl; system ("pause"); return 0; }

Explanation / Answer

#include <iostream>

#include <cmath>

using namespace std;

int main (){

    int a;

    int j=0;

    cout << "Please enter a number ";

    cin >> a;

    int temp=a;

    do{ //find the number of digits in number, store in j

        j++;

        temp= temp/10;

    }while (temp>0);

   

    int x=2;

    bool isPoly=true;

    while(x<=j){ //check for each number formed by taking first n digits, if its divisible by n

                double i;

                i= pow(10.0, j-x);

                temp=(int)a/i;

                if(temp%x != 0){ //if not divisible, no is not polydivisible

                          isPoly=false;

                          break;

                }

                x++;

    }

    if(isPoly)

              cout << "The number is polydivisible" << endl;

    else

        cout << "The number is not polydivisible" << endl;

    system ("pause");

    return 0;

}
