C++11 An unsigned integer type with the same size and alignment as uint_least32_t, which is therefore large enough to hold a UTF-32 code unit. const char32_t full_house[] = U"🂣🂳🂨🂸🃈"; // non-BMP characters std::cout << sizeof(full_house)/sizeof(char32_t) <<...

Interchangeable with class, except for the following differences: If a class type is defined using the keyword struct, then the default accessibility of bases and members is public rather than private. struct cannot be used to declare a template type parameter or template template parameter; onl...

Most PRAGMA statements affect only the current database connection, which means that they have to be re-applied whenever the database has been opened. However, the following PRAGMAs write to the database file, and can be executed at any time (but in some cases, not inside a transaction): applica...

An XSLT processor is necessary in order to perform any XSLT transformation. It can usually be installed via system's package manager. E.g. in Debian it can be installed with: sudo apt-get install xsltproc

A type specifier; when applied to a type, produces the const-qualified version of the type. See const keyword for details on the meaning of const. const int x = 123; x = 456; // error int& r = x; // error struct S { void f(); void g() const; }; const S s; s.f(); // error s...

Jumps to the end of the smallest enclosing loop. int sum = 0; for (int i = 0; i < N; i++) { int x; std::cin >> x; if (x < 0) continue; sum += x; // equivalent to: if (x >= 0) sum += x; }

C++11 Yields the type of its operand, which is not evaluated. If the operand e is a name without any additional parentheses, then decltype(e) is the declared type of e. int x = 42; std::vector<decltype(x)> v(100, x); // v is a vector<int> If the operand e is a class member...

In a switch statement, introduces a label that will be jumped to if the condition's value is not equal to any of the case labels' values. char c = getchar(); bool confirmed; switch (c) { case 'y': confirmed = true; break; case 'n': confirmed = false; break; default: ...

A named style requires the x:Key property to be set and applies only to elements that explicitly reference it by name: <StackPanel> <StackPanel.Resources> <Style x:Key="MyTextBlockStyle" TargetType="TextBlock"> <Setter Property=&qu...

An implicit style applies to all elements of a given type within scope. An implicit style can omit x:Key since it is implicitly the same as the style's TargetType property. <StackPanel> <StackPanel.Resources> <Style TargetType="TextBlock"> <...

It is common to need a base style that defines properties/values shared between multiple styles belonging to the same control, especially for something like TextBlock. This is accomplished by using the BasedOn property. Values are inherited and then can be overridden. <Style x:Key="BaseText...

A PDF document may contain the following standard types of signatures: Any number of approval signatures in signature form fields. At most one certification signature in a signature form field. It enables the author to specify what changes shall be permitted to be made to the document and what c...

In the Adobe technical white paper Adobe Acrobat 9 Digital Signatures, Changes and Improvements, especially its section "Allowed and disallowed changes", Adobe clarifies the allowed changes (as seen by Acrobat 9 and up) that can be made to a certified or signed document without invalidatin...

The specification says: A byte range digest shall be computed over a range of bytes in the file, that shall be indicated by the ByteRange entry in the signature dictionary. This range should be the entire file, including the signature dictionary but excluding the signature value itself (the Conte...
