Čika

Čika (Zadar, first half of 11th century - Zadar, after 1095; Latin: Chicca) was a Croatian benedictine nun, founder of the benedictine monastery of st. Mary in Zadar. She is also known for the illuminated prayer book known as Čika's book of hours, the oldest prayer book for personal use in Europe.

Life

She was the daughter of Dujam and Vekenega, niece of prior Madi, and the wife of Andrija.

She was the member of the noble patrician family Madi. After the death of her husband in 1066, she founded the monastery of St. Mary in Zadar with the help of her family. King Petar Krešimir IV referred to her as his sister when he placed the monastery under the royal protection, though such geneaology is debated.

She is the mother of Vekenega.

Record (computer science)

In computer science, a record (also called struct or compound data) is a basic data structure. A record is a collection of elements, possibly of different data types, typically in fixed number and sequence. The elements of records may also be called fields or members. A tuple may or may not be considered a record, and vice versa, depending on conventions and the specific programming language.

For example, a date could be stored as a record containing a numeric year field, a month field represented as a string, and a numeric day-of-month field. A Personnel record might contain a name, a salary, and a rank. A Circle record might contain a center and a radius—in this instance, the center itself might be represented as a point record containing x and y coordinates.

Records are distinguished from arrays by the fact that their number of fields is typically fixed, each field has a name, and that each field may have a different type.

A record type is a data type that describes such values and variables. Most modern computer languages allow the programmer to define new record types. The definition includes specifying the data type of each field and an identifier (name or label) by which it can be accessed. In type theory, product types (with no field names) are generally preferred due to their simplicity, but proper record types are studied in languages such as System F-sub. Since type-theoretical records may contain first-class function-typed fields in addition to data, they can express many features of object-oriented programming.

ALGOL 68

ALGOL 68 (short for ALGOrithmic Language 1968) is an imperative computer programming language that was conceived as a successor to the ALGOL 60 programming language, designed with the goal of a much wider scope of application and more rigorously defined syntax and semantics.

The contributions of ALGOL 68 to the field of computer science have been deep, wide ranging and enduring, although many of these contributions were only publicly identified when they had reappeared in subsequently developed programming languages.

Overview

ALGOL 68 features include expression-based syntax, user-declared types and structures/tagged-unions, a reference model of variables and reference parameters, string, array and matrix slicing, and also concurrency.

ALGOL 68 was designed by the IFIP Working Group 2.1. On December 20, 1968, the language was formally adopted by Working Group 2.1 and subsequently approved for publication by the General Assembly of IFIP.

ALGOL 68 was defined using a two-level grammar formalism invented by Adriaan van Wijngaarden. Van Wijngaarden grammars use a context-free grammar to generate an infinite set of productions that will recognize a particular ALGOL 68 program; notably, they are able to express the kind of requirements that in many other programming language standards are labelled "semantics" and have to be expressed in ambiguity-prone natural language prose, and then implemented in compilers as ad hoc code attached to the formal language parser.

C++ classes

A class in C++ is a user defined type or data structure declared with keyword class that has data and functions (also called methods) as its members whose access is governed by the three access specifiers private, protected or public (by default access to members of a class is private). A class (declared with keyword class) in C++ differs from a structure (declared with keyword struct) as by default, members are private in a class while they are public in a structure. The private members are not accessible outside the class; they can be accessed only through methods of the class. The public members form an interface to the class and are accessible outside the class. Instances of these data types are known as objects and can contain member variables, constants, member functions, and overloaded operators defined by the programmer.

Differences between struct and classes in C++

In C++, a structure is a class defined with the struct keyword. Its members and base classes are public by default. A class defined with the class keyword has private members and base classes by default. This is the only difference between structs and classes in C++.
