Determining if a number is either a multiple of ten or within a particular set of ranges

Question

I have a few loops that I need in my program. I can write out the pseudo code, but I\'m not entirely sure how to write them logically.

I need -

if (num is          


        

Answer 1

You can try the following:

// Multiple of 10
if ((num % 10) == 0)
{
   // Do something
}
else if (((num / 10) % 2) != 0)
{
    // 11-20, 31-40, 51-60, 71-80, 91-100
}
 else
{
    // Other case
}
