Hidden Features of PHP? [closed]
...lled on var_export()
public static function __set_state($array);
}
A C++ developer here might notice, that PHP allows overloading some operators, e.g. () or (string). Actually PHP allows overloading even more, for example the [] operator (ArrayAccess), the foreach language construct (Iterator ...
How do I pass multiple parameters into a function in PowerShell?
...
If you're a C# / Java / C++ / Ruby / Python / Pick-A-Language-From-This-Century developer and you want to call your function with commas, because that's what you've always done, then you need something like this:
$myModule = New-Module -ascustomobj...
What __init__ and self do on Python?
...ss. The self parameter refers to the instance of the object (like this in C++).
class Point:
def __init__(self, x, y):
self._x = x
self._y = y
The __init__ method gets called when memory for the object is allocated:
x = Point(1,2)
It is important to use the self parameter ...
Should I compile with /MD or /MT?
...it will cause the application to link with the static multithread Standard C++ Library (libcpmt.lib) instead of the dynamic version (msvcprt.lib) while still dynamically linking to the main CRT via msvcrt.lib.
So if I am interpreting it correctly then /MT links statically and /MD links dynamically....
Detecting programming language from a snippet
... but when a file extension matches multiple candidates (e.g. ".h" --> C,C++,ObjC), it will tokenize the input code sample and classify against a pre-trained set of data. The Github version can be forced to scan the code always without looking at the extension too.

Addition: C++ templates are essentially cut-and-paste at compile time with the correct values substituted. In C# the actual generic template (not an "instantiation" of it) exists after compilation and thus must (pardon the pun) be gene...
What tools are there for functional programming in C?
... lot lately about how to go about doing functional programming in C ( not C++). Obviously, C is a procedural language and doesn't really support functional programming natively.

Make a program run slowly
Is there any way to run a C++ program slower by changing any OS parameters in Linux? In this way I would like to simulate what will happen if that particular program happens to run on a real slower machine.

How to implement a binary tree?
...ge anything. My guess is that Fox is simply used to coding a language like C++ or Java, which require the semicolon at the end of the line. Aside from that optional use, semicolons can be used to chain statements in a single line. For example a=1; b=2; c=3 would be a valid single line in python.

Why does a function with no parameters (compared to the actual function definition) compile?
...t on, because it looks like a prototype (especially if you are poisoned by C++!), but isn't. It's an old style K&R C return type declaration.
Rule of thumb: Never leave an empty parameter list declaration empty, use int func(void) to be specific.
This turns the K&R return type declaration ...
