What is the rationale for fread/fwrite taking size and count as arguments?
...mplemented.
The Single UNIX Specification says
For each object, size calls shall be
made to the fgetc() function and the
results stored, in the order read, in

overlaying the object.

What is the command to exit a Console application in C#?
...Main with an int return type and return an error code that way. So there really is no need to use Environment.Exit unless you need to terminate with an exit code and can't possibly do it in the Main method. Most probably you can avoid that by throwing an exception, and returning an error code in Mai...

Computational complexity of Fibonacci Sequence
...ll have depth n and intuitively figure out that this function is asymptotically O(2n). You can then prove your conjecture by induction.
Base: n = 1 is obvious
Assume T(n-1) = O(2n-1), therefore
T(n) = T(n-1) + T(n-2) + O(1) which is equal to
T(n) = O(2n-1) + O(2n-2) + O(1) = O(2n)
However, as ...
