Pinguinsan got a reaction from SkilledRebuilds in What's That Song With The Melody That Sounds Like Rubber Chickens
Hey guys,
I have heard a song one or two times in the past two months or so. I'm not sure which Spotify channel it was on (it could be a newer song, it could be an older song). The only thing I can remember about it is that the melody in the song is very frantic, and it vaguely sounds like rubber chickens or some kind of horn. I don't remember if there are any lyrics to it.
If it was played often, I could just use Shazam (or whatever), but it doesn't play often and it's driving me nuts. I have tried Googling everything from "song that sounds like rubber chickens" to "song with very frantic pace"
Does anyone have any ideas or does this ring a bell?
Thanks,
-Tyler

Pinguinsan got a reaction from mrchow19910319 in Simple JS code.
If you're using Chrome or Firefox, you can test it yourself. Press F12 and click on "Console" in the developer window. Then paste that program inline:
function foo(b) { var a = 5; return a*b+10 } function bar(x) { var y = 3; return foo(x*y); } console.log(bar(6)) and hit enter. Should print out 100 as written.

Also, this code is amazingly horrible to read thanks to virtually no meaningful indentation.

Pinguinsan got a reaction from yuh25 in Statements that shouldn't be printed are printing. (C++14)
Clearly not, because he's asking the question.
In the constructor, you need to set the member "age" variable to the initialAge that is passed in. So change
if (initialAge > 0) { initialAge = age; } To
if (initialAge > 0) { age = initialAge; } So that age stores the initialAge passed into the constructor.

Pinguinsan got a reaction from ClobberXD in Unable to use std::thread - Part 2
Yep, you got it! One of the weird things that you don't really learn anywhere is why the "this" keyword is available in every member function, and it's because when you have a class member like:
class MyClass { public: void Func(); }; The ACTUAL signature to the member, generated by the compiler is
class MyClass { public: void Func(MyClass *this); }; And any time you call from any other class method, the compiler automatically adds the "this" pointer, so you don't have to:
void MyClass { public: void OtherFunc() { this->Func(); //Notice I don't need to include "this" when calling Func() } void Func() { } }; And indeed, you can't include the "this" pointer even if you wanted to, as it is implicit the the compiler.

Pinguinsan reacted to Unimportant in Unable to use std::thread - Part 2
And the reason, should anyone be interested, is that a instance of a class only contains the class's data (*). You can test this:
class Foo { int bar; public: // Add as much member functions as you like ... }; //You'll always get this... sizeof(Foo) == sizeof(int) If you have a million instances of this class you'll have a million int's, but the code for the member functions will exist only once, because it is always the same, only the data of a class changes.
That means, under the hood, this code must always receive a pointer to the instance data to work on.
(*) With some possible exceptions, such as a polymorphic class, which will probably also contain a vtable or some other extra data for the runtime dispatch mechanism.

Pinguinsan got a reaction from ClobberXD in Unable to use std::thread - Part 2
You must use pointer-to-member-function syntax when passing an instance level method (ie non-static, tied to an instance of MyClass), as well as the "this" pointer when creating a std::thread to an instance level member function.So change
std::thread t(&Func); to
std::thread t(&MyClass::Func, this); -
Pinguinsan reacted to stmfd sp!, {lr} in C++ for loop
Important note:
It will actually deduce: std::pair<const TKey, TValue>.
Which is another way that auto will save your ass. Since, if you used a range-based for loop with a map declared with, say, std::map<int, char> and tried to iterate it with a const reference to std::pair<int, char>, each iteration will produce a copy since the constness cast will be implicit. That's why using auto is a nice way to avoid situations where code that looks intuitive will actually produce implicit casts (and, therefore, copies).
Sorry for being pedantic.

Pinguinsan reacted to Unimportant in C++ for loop
Just as a interesting FYI for those who care:
One should be able to write:
isDivisibleBy(test, 2); Template type deduction should do the rest and remove the need for the explicit <int, int>.

Pinguinsan got a reaction from Merkey in Python or C for Raspberry PI 3?
As everyone else has said, it depends on what you want to do. The Raspberry Pi ships with Python GPIO support out of the box (or with an apt-package, I can't remember), but it's equally easy to install wiringPi and use the arduino-style interface.

Pinguinsan reacted to fizzlesticks in Review for C# style String.Format() in C++
Because they're template arguments, doing
template <typename First, typename ... Args> std::string TStringFormat(const char *formatting, First&& first, Args&& ... args) Would make them forwarding-references / universal-references, not rvalue references. It would be beneficial for any type that could be converted to a string by moving. So for a std::string you would do a move instead of a copy and user defined types would be able to take advantage of it. For example, if you wanted a Book to be toStdString-able and the string is just the title of the book you could have the overload:
std::string toStdString(Book&& rhs) { return std::move(rhs.title); }
Also I don't know if it was intentional but your function is inconsistent for strings with recursive "{x}"s.
std::cout << TStringFormat("{0} {1}", "{1}", 20); //outputs "20 20" std::cout << TStringFormat("{0} {1}", "{10}", 20); //ouputs "{10} 20" I would expect either the first to output "{1} 20" or the second to throw an index out of range exception depending on if you want to allow recursive look ups or not.

Pinguinsan reacted to fizzlesticks in Review for C# style String.Format() in C++
You're missing #include <sstream>
The static_cast<std::string>s in toStdString are unnecessary. They will basically get transformed into static_cast<std::string>(std::string(rhs)); making the cast pointless. If you want to be explicit about it, just doing return std::string(rhs); would be better.
The parameters for TStringFormat should all be const.

Yes it would.

Pinguinsan got a reaction from Blade of Grass in How to make a array of pointers?
Of course when passing a non-pointer type to a function, it will create a local stack copy. My comment was regarding using an "array" as an argument to a function, not for passing regular types.
And yes, while you are technically correct that C does not pass by reference (a function taking a pointer as an argument takes the value of the pointer), everyone knows what you mean when you say it.
"pass by reference".

Pinguinsan got a reaction from mathijs727 in How to make a array of pointers?
This is correct, and bound to bite every beginner C and C++ programmer sooner or later, especially when trying to pass arrays to functions. See below:
#include <stdio.h> #define ARRAY_SIZE(x) sizeof(x)/sizeof(x[0]) //Deceiving, because (EDIT: pointer/array) arguments to functions are ALWAYS //simply pointers, NOT arrays void arraySize(char charArray[]) { printf("ARRAY_SIZE(charArray) = %zu\n", ARRAY_SIZE(charArray)); //Prints 4! } int main() { char myCharPointer[50]; //Allocates an array of size 50 on the stack printf("ARRAY_SIZE(myCharPtr) = %zu\n", ARRAY_SIZE(myCharPointer)); //Prints 50 arraySize(myCharPointer); }
