Representation and manipulation of rational numbers in C++

By Hassnain Jamil -

Requirements

Task is to define a class to represent and manipulate rational numbers (fractions), so that by simply changing the type of n1 and n2 to Rational the program will compute fractional

arithmetic expressions such as these:


1/2 + 1/3 // answer: 5/6
1/3 - 1/4 // answer: 1/12
2/3 * 4/5 // answer: 8/15
3/7 / 2/3 // answer: 9/14

Download the file fractions_0.zip, which contains the calculator code and a skeleton version of the Rational class. The class defines (but doesn't fully implement) appropriate constructors to initialise instances of Rational, extract and insert operators for input and output of Rational values, and of course arithmetic operators to compute the results.

[SOLVED] Tape for a Turing Machine using Doubly-linked List in Java with full source code

By Anonymous -
Tape for a Turing Machine (Doubly-linked List) Short exercise in which you will code part of an existing project. In this case, you will be working with a doubly-linked list. To make this topic more interesting, the list that you work on will be part of a Turing Machine. A Turing Machine is a kind of very simple, abstract computing device that was introduced in the 1930's by Alan Turing as a way of studying computation and its limitations. The classes that you need for the lab are in a package named turing. You will define a new class named Tape in this package. You can find the Java source in the code directory. You should copy this directory into an Eclipse project. There will be errors, since the existing classes depend on the Tape class, which you have not yet written. Don't forget the Javadoc comments. A Class for Turing Machine Tapes A Turing machine works on a "tape" that is used for both input and output. The tape is made up of little squares called cell

[SOLVED] Branch Coverage, Statement Coverage and Path Coverage | Java Unit Testing

By Anonymous -
Create a directory called “TestClassValue” Hereafter, we call this directory <dir>. Create a Java class com.work.sample.FlawedClass in directory <dir>/src. (The actual path will obviously reflect the package structure.) 100% Branch Coverage & 100% Statement Coverage Add to the class a method called flawedMethodl that contains a division by zero fault such that it is possible to create a test suite that achieves 100% branch coverage and does not reveal the fault every test suite that achieves 100% statement coverage reveals the fault. Conversely, if you were able to create the method, then create two JUnit test classes com.work.sample.FlawedClassTestBCl and com.work.sample.FlawedClassTestSCl for class FlawedClass as follows: FlawedClassTestBCl should achieve 100% branch coverage of flawedMethodl and not reveal the fault therein. FlawedClassTestSCl should achieve 100% statement coverage of flawedMethodl and reveal the fault therein. Both classes should be
