Is there an exponent operator in C#?
...o in most programs, and
it doesn't seem justified to add an
operator when calling Math.Pow() is
simple.
You asked:
Do I have to write a loop or include
another namespace to handle
exponential operations? If so, how do
I handle exponential operations using
non-integers?

Iterating C++ vector from the end to the beginning
...;
i != my_vector.rend(); ++i ) {
}
rbegin()/rend() were especially designed for that purpose. (And yes, incrementing a reverse_interator moves it backward.)
Now, in theory, your method (using begin()/end() & --i) would work, std::vector's iterator being bidirectional, but remember,...

Notice that this does not measures "non-element attributes of the array object" so the actual size in bytes can be a few bytes larger th...
Fastest way to determine if an integer is between two integers (inclusive) with known sets of values
...s an old trick to do this with only one comparison/branch. Whether it'll really improve speed may be open to question, and even if it does, it's probably too little to notice or care about, but when you're only starting with two comparisons, the chances of a huge improvement are pretty remote. The c...
Force line-buffering of stdout when piping to tee
Usually, stdout is line-buffered. In other words, as long as your printf argument ends with a newline, you can expect the line to be printed instantly. This does not appear to hold when using a pipe to redirect to tee .

OnChange event handler for radio button (INPUT type=“radio”) doesn't work as one value
... It would be better to cache the function outside the loop, so that all radios share the same event handler (now they have identical handlers but they are different functions). Or maybe put all radios inside a wrapper and use event delegation
