Okay, by "low-order bit position" do you mean the "least significant digit"? As in, if you have 1001 then the right-most one (1001) would be the low-order bit position? If so, you could describe that as being in the "one's place" (as opposed to "ten's place" and "hundred's place" in decimal or the "two's place" and "four's place" etc. in binary). Because in the decimal number 823, the "3" means "3" but the "8" really means "800", you would say the 3 is "less significant" or "lower order" than the 8.

And for "single-value parameter", can you just rephrase it as "a parameter that only has one value in it" or "a parameter that is only one value"? Please help me to understand what you are asking for, by letting me ask you what exactly you mean using these examples:

int some_function(x, y, z); <-- has 3 parameters

void function_one(some_array); <-- If it is an array, does that mean it is one parameter, but not a single-value parameter?

int n;

void function_two(n); <-- has 1 parameter, assume n is passed by value not reference...

Is the last example what they mean by a "single-value parameter"?

And I would assume the same is true for "one-element object", that it would be "an object that has only one element in it", as opposed to a large object with data and methods? I think for the last two you can just rephrase them as I did and it will make sense. Am I right?
