Problem 9 - 2, Programming in C

The initial equations for N1 and N2 are either wrong or I don't get them. The formula for N ends with the term "+day" which, for August 8, 2004 should be 8, not 3 as the book shows. Also, the N2 calculation for February 22, 2005 should end with +22 not +21 as the book shows, shouldn't it? Additionally, it is not stated anywhere in the problem but I assume all divisions carried out are integer divisions. Is all this correct?

Yes, it's all integer division. And yes, your corrections to the numbers in the example are correct.
Thanks,

RE: ex 9.2. I found this example very confusing. I'm sure trying to decipher the math was not the point of the exercise.
This is the point in the book where I get lost not having a strong math background. Any clarity would be appreciated.
I otherwise found this book very helpful. tf

Hell I didnt look at the formula too close and thought it was some set boilerplate formula for this.Wondered why the formula for n1 and n2 were different.
why wasnt it just explained as something like: i=1461*f/4+153*g/5+(whatever day variable or structure day variable here);
