I am grouping them since our instructor left this note for us, but I'm not sure how to correctly group them in code so the >= and >= is done before the &&.

Answer 2

Yes. The >= and <= has a higher precedence than the logical operator. Even whether they are grouped properly or not, the result is the same.

Answer 3

See where my instructor said "when in doubt add your own parentheses?

That's what I'm trying to do, but I'm not sure how to do so correctly.

However, I figured it out.

if ( (BMI > NUMBERFORBMIRANGE) && (BMI < SECONDNUMBERFORBMIRANGE))

Answer 4

Correct. You missed the outer parentheses of the if statement. :)
