Answer #1

In a autocorrelation function "k" is the time gap and is also known as lag. If a time lag of 1 autocorrelation then it means that the values are one time period apart. Hence the lesser the time period the lesser the variations.

So the correct answer is option a. Use a smaller k

    Background: The purpose of this assignment is to practice dealing with exception handling and textual data. Exception handling is a very important part of being an object-oriented programming. Rather returning some kind of int return value every time you tickle an object, C++ programmers expect methods to focus on their task at hand. If something bad happens, C++ programmers expect methods to throw exceptions. When caught, exceptions can be processed. When uncaught, they cause a program to terminate dead in...
