{

    double a,b,c,d,m,n=2,mn;
    cin>>a>>b;
    c=a/100;
    d=b/100;
    while (1)
    {m=1;
     while (m<n)
    {mn=m/n;
     if ((mn<d)&&(mn>c)) break;

This is my project Got WA on test14.
I think there's something wrong with digits
But i cannot find it
Can anyone help me with it?
Thx!
I think, your mistake in precision. Try change:
if ((mn<d)&&(mn>c)) ->
if ((mn+eps<d)&&(mn-eps>c))
