Discussing Variables and Constants

Define and study the terms "variable" and "constant" as used in computer programming. Determine the various types of data (such as char, int, double, string, and date) that can be used in developing a solution. Describe how and when you would use one over the other in a simple solution to calculate the grade average for a class.

Variables in a Programming Language

Consider the following program: List all the variables, along with the program units where they are declared, that are visible in the bodies of Sub1, Sub2, and Sub3, assuming static scoping is used. procedure Main is X, Y, Z : Integer; procedure Sub1 is A, Y, Z : Integer; procedure Sub2 is

UDP and multicast

Describe and discuss what the UDP does and its relationship to TCP - in what ways is it similar and different, and why (what applications) would we use UDP, and why can't a user program access IP directly? What is multicast, how is it used, also include some of the constraints and solutions to those constraints. Provide a

Create a Query to Produce an Output

Create a query to produce the output shown in the figure below. The output, derived from the CHARTER and MODEL tables, is limited to February 6, 2004. (Hint: The JOIN passes through another table. Note that the "connection" between CHARTER and MODEL requires the existence of AIRCRAFT, because the CHARTER table does not contain a

Write a Program to Calculate Weekly Pay

A company pay its employees as managers (who receive a fixed weekly salary), hourly workers (who receive a fixed hourly wage for up to the 40 hours they work and "time-and-a-half"- 1.5 times their hourly wage- for overtime hours workers), commission workers (who receive $250 plus 5.7% of their gross weekly sales), or pieceworker

Document Content Validation

Please help with the following problem. Do you think that any form of document content validation should be applied to web pages before they are placed in the public domain? That is, some form of assurance that they do not contain completely incorrect information. As opposed to censorship, this could be some form of assura

Currency Conversion Program

Expand the "Currency Conversion" program to have a menu of five currencies that allows the user to choose which currency they wish to display in its equivalency to the US dollars. The choise selected by the user will be error checked (which means that it is error checked (crash proof, I might test it with any type of input) as a

"Use cases" may be based on well-written natural language requirements. 4. In the design process, workflow diagrams define the entire business process. 5. Encapsulati

2DIM-DFA is undecidable

The language define by the equality of two 2DIM-DFA machines on all inputs is undecidable. The full definition of 2DIM-DFA can be found in Sipser's "Introduction to the Theory of Computation" (5.17) I show a reduction to the decidability of a problem which is known to be undecidable and hence prove the undecidability of the o

NP-Harp

Recall, in our discussion of the Church-Turing thesis, that we introduced the language D = {p | p is a polynomial in several variables having an integral root}. We stated, but didn't prove, that D is undecidable. In this problem you are to prove a different property of D, namely, that D is NP-hard. A problem i
