Program Plan Intro

Implementation of modified version of the Interpreter code which continue its execution even after finding an error.

Program plan:

  • Define a class named “IdNode1()” for declaring identifiers and it values.
  • Define a friend class named “Statement1()” with functions to process the expressions.
  • Define a function named “findValue1()” to check the expression has a identifier or not. If not throws an error message.
  • Define a function named “processNode1()” to handle the node with an expression.
  • Define a function named “readId1()” to read the input identifier and provides an error if the user enters no identifier.
  • Define a function named “factor1()” to get each and every factor in the term and provides an appropriate error messages.
  • Define a function named “term1()” to get each and every term in the expression and provides an appropriate error messages.
  • Define a function named “expression1()” to get the expression and provides an appropriate error messages..
  • Define a function named “getStatement1()” to handle the input expressions and provides an appropriate error messages.

If a UDP datagram is sent from host A, port P to host B, port Q, but at host B there is no process listening to port Q, then B is to send back an ICMP Port Unreachable message to A. Like all ICMP messages, this is addressed to A as a whole, not to port P on A. (a)  Give an example of when an application might want to receive such ICMP messages. (b)  Find out what an application has to do, on the operating system of your choice, to receive such messages. (c)  Why might it not be a good idea to send such messages directly back to the originating port P on A?

This week we will be building a regression model conceptually for our discussion assignment. Consider your current workplace (or previous/future workplace if not currently working) and answer the following set of questions. Expand where needed to help others understand your thinking:  What is the most important factor (variable) that needs to be predicted accurately at work? Why? Justify its selection as your dependent variable.
