UNDERSTANDING THE PROBLEM : ARITHMETIC OPERATIONS BETWEEN ORDINARY FRACTIONS
ADDITION, SUBSTRACTION, AND MULTIPLICATION OPERATIONS

[img]http:///a/img673/7564/rV1occ.png[/img]

From the Above we can see Similarities between them. Understanding these would aid coding.
Division Operations is a little different

[img]http:///a/img661/7716/5R1vDr.png[/img]

That Understood.
We know all we need to begin the Development.

So Let’s Get CODING !!!

Question: But Oga Jacobu , We’ve not Discussed about mixed fractions how can we begin coding?

Answer: According to Agile Practices, You don’t need to know all about your system before you get coding (Water Fall). We just need to know part of the system that is most needed currently and independent of other areas of our project or system not yet implemented. We’d treat that in other next iteration so we log that feature in our iterations backlog .

That Said…. LET’S GET THE TESTS ROLLING

UNDERSTANDING THE PROBLEM : FRACTION ARITHMETIC

Before we jump unto our systems and get the test running and the codes rolling we need to understand the problem

So what is a fraction ?
According to Wiki, hmmm..blah blah

Types:
Mixed Fractions and Ordinary Fraction
[[img]http:///a/img633/1702/Z3CiYM.png[/img]

That understood. How are Arithmetic Operations Performed between two fractions ?

PROGRAM REQUIREMENTS
Our Program is to accept as input integers representing values that compose two fractions (Mixed or Ordinary Fraction) and Perform Arithmetic Operations on them.
The operations include:
Additions
Subtractions
Multiplication
Division
Comparisons (Equals and Not Equals)

Fractions can also be:
Incremented
Decremented
Outputted in Human Readable form

POST 2:
What’s Test-driven development?
TDD , is a disciplined programming technique built around a simple idea:

no production code is written before there’s a failing test that justifies the existence of that code.

That’s why it’s sometimes referred to as test-first programming.

It’s more than that; by writing a test first, you drive your production code toward a design called for by the test.
This has the following desirable consequences:

Code becomes usable —The design and API of your code are suitable for the kind of
scenarios you’re going to use it for.

Code becomes lean —The production code only implements what’s required by
the scenarios it’s used for.

The Fundamental Test Life Cycle

[size=30pt] The Golden Rule of Test-Driven Development [/size]
[size=25pt]
Never write new functionality without a failing test. [/size]

Won’t be boring you with the jargons of TDD. I’d advise you google Books on it to Learn more.

TOPIC: Tutorial: Building a Simple Fraction Arithmetic Program in C# using TDD

Hi, Everyone. I’ve been learning TDD (Test-Driven Development) for a (longggg) while now and I’m revisiting it now for good. I’d like to have firm crisp of it and implement it in my existing projects and new ones.
So I’m writing this tutorial to aid my knowledge.
Note: This is my first tutorial on any forum. Expect Typos (Lolz)
I’m Building a Simple Fraction Arithmetic Program in C# using Test-Driven Development Method.
Pls, Creative , criticisms and corrections are strongly welcomed.

Programming / Re: How Can I Create A Virus Or Malware? by jacob05(m): 4:11pm On Jul 31, 2015
First (obviously) you'd need to learn a programming language... That'd let you know the basics of how programs run, their behaviours and logic... I'd advise you learn Python...or hmmm C++

Then learn how old viruses that made waves were designed and the logic behind them..

Learn debugging....(not saying much)

Subscribe to exploits sites too. As they provide info on vulnerable apps..(targets) wink.. peace

Sure... You've got experiences with other languages like PHP or Java.. you should be able to.. But it takes more than a Month to master its usages just like any other language.

Seun:
Never mind that; apologies. How does your code work?


It implements the MARF, The Modular Audio Recognition Framework, to do Training and Recognition http://marf.sourceforge.net/.

The MARF comes with a bundle of FEATURE EXtraction Methods to sample audio for "speaker properties" and Classification Methods ..

The program stores "speaker properties" analysed using LPC (Linear predictive coding ) and MAHALANOBIS_DISTANCE Classification Method in the DB when a audio file is inputted for training with a default id 0f 1.

The MARF recognize method enable input of a sample audio file which is analysed for "speaker properties" using the set FEATURE EXtraction Methods and Classification Method and then matched with "speakers properties" in it repository.

MARF would always return a match so the program calculates the probability of the matched id and if it is high enough (used >=0.75) then the speaker is recognized.

Note: It is also a fork of a user ucungsr
Don't know how to explain much but hope I'm clear enough.

Let me explain once and for all the kind of buhari your app must capture:
- Buhari's voice when he was a baby (crying)
- Buhari when he was a teenager
- Buhari before He became president
- Buhari when he had a cough and sorethroat
- Buhari if he is speaking with his mouth full (but he shouldn't anyway)

And it must be able to detect it was buhari:
- when he speaks in a party with jamz rocking
- when his voice is broadcasted from a megaphone across the street
- when his recorded voice is being played with my nokia 3310
- my daddy's record discs

Under the following moods:
- happy
- sad

Under the following moods:
- crying
- singing

In the following dimensions:
- Mono
- Stereo
- 3D surround

In the following weather conditions:
- Heavy rain with winds blowing
- Thunderstorm situations


Well. . . . .if your code can fulfill all that, I see no reason why you should not win the award

- Happy coding



exactly my observations too.

40k? Why don't you collect 50k from Oga Seun by submitting ur code to him.. you'd earn 10k more..
