    my code isnt working..please tell me why

    int main() {
    
    long int i=0,j=0,k=0,m=0,x=0,d=0,r=0;
    cin>>i>>j>>k;
    for(m=i;m<=j;m++)
    {
        r=0;
        while(m!=0)
        {
            d=m%10;
            r=r*10+d;
            m=m/10;
        }
        if((abs(r-m)%k)==0)
            x++;
    }
    cout<<x;
    return 0;
}

      Dude, you are using same m in your code... which will keep on becoming zero after completion from while loop and it will never be equal to j, better try out with this:

      include

      include

      using namespace std; int main() {

      long int i=0,j=0,k=0,m=0,x=0,d=0,r=0,m1=0;
cin>>i>>j>>k;
for(m=i;m<=j;m++)
{
    r=0;
    m1=m;
    while(m1!=0)
    {
        d=m1%10;
        r=r*10+d;
        m1=m1/10;
    }
    if((abs(r-m)%k)==0)
        x++;
}
cout<<x;
return 0;

      } I hope you got what's wrong.

      in this when the loop run for the first time the vue of m becomes 0. so we again give the value of i to m and so Infinite loop runs
