Once using is used to introduce the name cout from the namespace std into the scope of the main function, the std::cout object can be referred to as cout alone. #include <iostream> int main() { using std::cout; cout << "Hello, world!\n"; }

If a using-declaration occurs at class scope, it is only allowed to redeclare a member of a base class. For example, using std::cout is not allowed at class scope. Often, the name redeclared is one that would otherwise be hidden. For example, in the below code, d1.foo only refers to Derived1::foo(c...

C++11 As a special case, a using-declaration at class scope can refer to the constructors of a direct base class. Those constructors are then inherited by the derived class and can be used to initialize the derived class. struct Base { Base(int x, const char* s); }; struct Derived1 : Base {...

PyTesseract is an in-development python package for OCR. Using PyTesseract is pretty easy: try: import Image except ImportError: from PIL import Image import pytesseract #Basic OCR print(pytesseract.image_to_string(Image.open('test.png'))) #In French print(pyt...

Another module of some use is PyOCR, source code of which is here. Also simple to use and has more features than PyTesseract. To initialize: from PIL import Image import sys import pyocr import pyocr.builders tools = pyocr.get_available_tools() # The tools are returned in the recommended...

Block will capture variables that appeared in the same lexical scope. Normally these variables are captured as "const" value: int val = 10; void (^blk)(void) = ^{ val = 20; // Error! val is a constant value and cannot be modified! }; In order to modify the variable, you need to ...

In the case of a discriminated record type, some of the components are known as discriminants and the remaining components can depend upon these. The discriminants can be thought of as parameterizing the type and the syntax reveals this analogy. In this example we create a type that provide a sq...
