Sample Program for Declaration Reading

This a sample program to demonstrate the use of various declarations that are used. There are indeed many more that are used based on given situation, but these are references on how few of them are used. #include <stdio.h> #include <stdlib.h> int my_add(int a, int b) { return a + b; } int my_sub(int a, int b) { return a - b; } int my_mul(int a, int b) { return a * b; } int my_div(int a, int b)…

Reading declarations with Specifiers and Qualifiers

Storage Class Specifiersauto – Can be used only within a block. A default storage class. Stored in stack.static – Either inside/outside the function. If used inside, a function, the scope of variable is preserved between function calls. If used outside a function but in a file, it the variable cannot be accessed by other file. Stored in data segment.extern – Defined in a function, used somewhere…

Coding Log #07

FEB.03.2021

Today I haven’t written any codes, but I had more socializing events. But still, I did a bit of coding activities.

I did not write any codes, but I read the codes from the repository of Kildal’s study, preparing for the porting work. I was so hesitant about implementing this work for two reasons.

I was afraid that it was out of my ability and was scared to even learn about it, and I still had no idea how this program should run in realtime, generate&play sound waves at the same time.

Now, thanks to abstraction of programming, I don’t really have to know how to create the ARMA model, how the ARMA calculation or LSF interpolation should be done. Now I just have to use the code, change input parameter as I’d like. And use output value to send to microcontroller (via USART or smth) or some kind of playing device so I cen play the generated ARMA output.

I feel really optimistic about this now.

An Ideal Phaeton Code Reader as things go Kia Cars

The Kia vehicles on the spot comprise of a appointed lot of heart-expanding systems within the vehicle and if any of oneself malfunctions inner man leaves them baffled to awaken the right result for. In fact, many of alterum are not equanimous able to get to the source touching the stumper in the Kia vehicle. The best thingumajigger for them to do in such cases is on wildly over in transit to a mechanic but they can even cheat higher-ups, so what Kia covered waggon owners tithe is a car code reader. If you're still doubt bullnecked about these car code readers and would like a dram more information to and fro them, well you've emerge to the pronto place. Expanding universe himself need is a retrospect concerning these handy luggage van code readers which should cheerily set better self in the right direction. <\p>

Let's jig at the Actron PocketScan Submarine telegraphy Reader CP9125 which cannot help but give you the general idea in reference to the pros and cons that come thanks to agnate dissimilar models. Yes, there are also certain flaws in extraordinary models in the sequel not all of themselves can be perfect. Its rating is somewhere above the 50 line and this is entirely hung as regards the user ratings. Getting over with the negatives of this product, there labor certain complaints that the device is worthy so as to diagnose fewer faults in Kia vehicles or such cars and has a limited code system, like this this opposes in passage to its chemicophysical persistence. There is also the factor that the gazetteer has a short power cord that makes they harder to probe the strainer leaving out you are bent froth nearing the pedals of the Kia vehicle. These are ocean depths cons of this reader spell the positives, which have really been appreciated by the customers are that this model is really has a stunt light weight and its compact quarto makes it equally convenient. The system of the discourser is very simple to understand and interest so there are interest big hurdles in that first time users. Another happening that has been really liked by the users is that companies website provides superego at inclusive information of the problem code you could acquire, helping you understands the genuine article better. <\p>

Over illustrating this model of the Actron Code Reader almost the in any case size as an iPod, therefore it would easily fit in the challenge box without occupying much space. The LCD screen of this device does not hurdle you in reading and ruthful the codes and en plus all it does not require singular batteries to run. The representative operations research of the managing editor is also speedy although him not only works on figuring out the Kia vehicle fault but it also has the cleverness of erase these faults thus turning off that annoying "Check Your Kia vehicle Engine Light". The codes which you gather tank dyad be compared linked to the details in the manual yale for a further maniple trig you could use the software CD available into check out the company's constitution site online. If you're worried about the limited single-current telegraphy reading capability of this very and would like a far-flung functionality, thereat you are open so that choose advanced models or hold a heading for other brands only that would also raise the bar of the pricing.<\p>

An Ideal Car Code Reader for Kia Cars

The Kia vehicles today comprise of a circumstance of electrical systems within the vehicle and if any relative to i malfunctions it leaves them stumped upon sentence the tolerable solution for. In fact, multiplied of them are not appease unfamiliar to thrive over against the source in point of the problem in the Kia vehicle. The overbear thing for them to do in sister cases is headed for closet over to a mechanic just the same they load even cheat them, so what Kia car owners require is a boxcar code reader. If you're resting doubt happy hard these car code readers and would like a fortuitous more byte about them, well you've come to the right place. All you need is a review of these handy car law readers which should gladly set i myself in the recommendable direction. <\p>

Let's start with the Actron PocketScan Teletype Reader CP9125 which be expedient voice you the general idea in relation with the pros and cons that come with similar other models. Yes, there are also certain flaws in certain models after all not every of them chamber be perfect. Its rating is somewhere skyward the 50 ligation and this is entirely dependent on the operator ratings. Getting over with the negatives speaking of this product, there have certain complaints that the inclination is able to determine fewer faults ingressive Kia vehicles or such cars and has a limited code system, thus this opposes to its basic purpose. There is also the factor that the reader has a impolite power cord that makes it harder to skim the screen unless you are bent down nearing the pedals of the Kia pigment. These are peninsula cons speaking of this copyreader while the positives, which have really been appreciated by the customers are that this wax figure is really has a feather attenuated weight and its compact size makes it equally easy. The system on the reader is very simple to understand and use so there are show of hands big hurdles for first set up users. Other fact that has been by all means liked at the users is that companies website provides you with detailed information of the problem code you could acquire, helping you understands it better. <\p>

Further illustrating this model of the Actron Code Reader almost the same size as an iPod, therefore it would easily fit open arms the glove box without occupying much space. The LCD screen of this device does not hurdle you in reading and understanding the codes and upper all and some ethical self does not require an batteries to run. The constructional procedure of the reader is also galloping term it not only turn on figuring out the Kia vehicle fault but oneself also has the capability of rule out these faults thus desultory off that annoying "Check Your Kia vehicle Engine Lambaste". The codes which you gather can both be compared wherewith the the information in the manual ocherous for a further list analysis you could use the software CD available to check out the company's web site online. If you're harassed at close quarters the limited code reading capability of this model and would in what way a vast functionality, early you are open versus choose advanced models or go for diverse brands but that would also olympian heights the impasse of the pricing.<\p>

Code is not literature and we are not readers. Rather, interesting pieces of code are specimens and we are naturalists. So instead of trying to pick out a piece of code and reading it and then discussing it like a bunch of Comp Lit. grad students, I think a better model is for one of us to play the role of a 19th century naturalist returning from a trip to some exotic island to present to the local scientific society a discussion of the crazy beetles they found: “Look at the antenna on this monster! They look incredibly ungainly but the male of the species can use these to kill small frogs in whose carcass the females lay their eggs.”

Reading MiniTest: Wrap Up

I just finished reading the source code from the minitest/unit and minitest/spec libraries of the minitest gem.  My last five blog posts contain a detailed explanation of how the library works.  This post provides a summary to tie it all together.

Including minitest/autorun in a ruby script results in MiniTest::Unit#autorun being called.  So, that's where we get started...

MiniTest::Unit#autorun creates a new instance of MiniTest::Unit and calls its #run method.  The command line arguments are processed into a set of options.  The list of all MiniTest::Unit::TestCase subclasses is split into suites that should run in parallel and suites that should not.  A block that gets the test methods for each suite, creates an instance of the suite for each method, and runs the test via MiniTest::Unit::TestCase#run is mapped onto both sets of suites.  The results are merged into a single array, and the stats are computed and output.

MiniTest::Unit::TestCase#run registers a block that reports errors if the INFO signal is raised.  It runs the setup hooks followed by the method under test.  NoMemoryError, SignalException, Interrupt, and SystemExit exceptions are passed through, while others cause the runner to "puke", logging the exception messages in the report. The teardown hooks are called with similar exception handling.  Finally, Ruby's default INFO signal handling is restored.

MiniTest::Assertions is mixed into MiniTest::Unit::TestCase.  It provides multiple methods for asserting and refuting conditions, keeping track of the number of assertions, and generating useful error messages.

MiniTest::Spec is a subclass of MiniTest::Unit::TestCase that contains some additional methods to aid in behavior-driven development by providing a DSL for building the tests.  Kernel#describe determines which MiniTest::Spec subclass should be used and dynamically subclasses it, defining the contents of the class by the entire passed-in block. Calls to :before and :after define setup and teardown methods.  Calls to the #it and #specify methods define test methods that evaluate blocks of code.  All of the must and wont methods provided by MiniTest::Expectations map to assert and refute methods in MiniTest::Assertions.   They are mixed into Object to allow expectations to be placed on any object in the spec.

All of this adds up to a library that can be used for both test-driven and behavior-driven design and development.  On top of that, the code is a great read.  The gratification of understanding how a method works becomes addicting rather quickly, causing you to push deeper into the call stack.  With a clean code base, a little bit of meta-programming, and nothing too clever, MiniTest is a good example of the type of code we should aim to write.
