The Ring programming language version 1.9 book - Part 94 of 210Mahmoud Samir Fayed
This document discusses using a code generator to wrap C/C++ libraries for use in Ring applications. It describes the key components needed:
1. A configuration file that specifies the C/C++ function prototypes and structures to wrap.
2. The parsec.ring code generator program that takes the configuration file and generates C code wrapping functions.
3. Features of the configuration file like adding code snippets, setting function name prefixes, and specifying structures to wrap.
The code generator significantly reduces the effort to interface Ring with existing C/C++ libraries by automatically generating the wrapper functions and handling data type conversions between the languages.
The document discusses functors, applicatives, and monads in Haskell. It provides examples of how functors allow lifting functions to work on container types like Maybe and Logger using fmap. Applicatives allow applying functions to multiple arguments within a container using <*>. Monads generalize applicatives by allowing chained computations through >>= and return, handling context and effects like logging.
The document discusses Java 8 Stream API, which provides a new way to process collections of objects. It introduces key concepts of streams such as intermediate and terminal operations, and examples of using streams to filter, map, sort and collect data. Common intermediate operations include filter, sorted, map, and terminal operations include collect, reduce, count. Streams can make processing collections more declarative, optimize parallel operations, and abstract away iterations.

Arrry structure Stacks in data structurelodhran-hayat
There are two types of arrays in C++: single dimensional and multidimensional arrays. The document then provides examples of using single dimensional arrays, traversing arrays using for loops and foreach loops, using structs with constructors and methods, pointers including declaring, assigning, and dereferencing pointers, and dynamic memory allocation using new and delete operators for built-in types, arrays, objects, and multidimensional arrays.
This C program implements a bubble sort algorithm to sort 6 characters in an array from largest to smallest. It initializes an unsorted array, compares adjacent elements, and swaps them if out of order, repeating until the array is fully sorted. The sorted array is then printed out.
"Немного о функциональном программирование в JavaScript" Алексей КоваленкоFwdays
This document discusses functional programming concepts in JavaScript including imperative vs declarative programming, currying, composition, functors, and the Ramda library. It provides examples of implementing curried functions, function composition, and functors in JavaScript. Functors are discussed in the context of arrays and the Maybe datatype. The Ramda library is presented as an alternative to Underscore/Lodash that follows a more functional programming style with its use of currying and function composition.
This document discusses JavaScript functions and related concepts. It defines functions, classes, and methods. It shows how functions can take arguments, be passed as callbacks, return other functions, and create closures. Classes can be defined using functions with the new keyword or by adding to prototypes. Built-in types like Number, String, and Array can be constructed or assigned directly. Functions are first-class objects that can be assigned and passed around.
The document discusses JavaScript compilation and execution. It describes how the JavaScript engine first goes through a compilation phase, creating variable objects and determining scope, before executing code. During execution, it first enters a global execution context and then creates new execution contexts for each function invocation, with their own variable objects and scope chains. It provides examples to demonstrate how code is compiled and executed, including variable and function declarations and how scopes and contexts are set up.
The document discusses Java 8 lambda expressions and functional interfaces. Key points include:
- Lambda expressions allow for anonymous methods that can access local variables and don't require a class file.
- Functional interfaces define a single abstract method, representing a function contract.
- Default methods allow interfaces to provide default implementations of methods.
- Method references provide a way to refer to a method without invoking it.
This document discusses monads in functional programming. It provides examples of optionals, arrays, and functions in Swift that exhibit monadic properties. It then defines monads more formally and describes some common monad types like the writer, reader, and IO monads. It shows how monads allow encapsulating effects like logging or environment variables while preserving referential transparency. The document concludes by discussing potential applications of monads to mobile apps.
The document contains two questions asking to implement data structures in C++. Question 1 asks to implement methods for a singly linked list including returning size, printing, checking containment, adding, and removing values. Question 2 asks to implement methods for a queue using an array including initializing, checking for empty/full, accessing front/back, adding, and removing elements. Sample code is provided for both a linked list and queue implementation with the required methods.
The document discusses queues and their implementation. It defines a queue as a FIFO data structure where new items are added to the rear and removed from the front. Key queue operations are described like add, remove, isEmpty and isFull. The document then provides examples of implementing a queue using arrays and pointers in C++. It includes functions for initialization, insertion, removal, checking if empty, and printing all elements.
Queue Implementation Using Array & Linked ListPTCL
This document describes two implementations of a queue data structure in C++. A queue uses the First In First Out (FIFO) principle to add and remove elements. Elements can be added to the rear of the queue using the Enque operation and removed from the front using the Deque operation. The first implementation uses an array to store queue elements, while the second uses linked nodes to dynamically allocate memory for elements as they are added. Both implementations provide functions for Enqueuing, Dequeuing, checking if the queue is empty, and displaying the queue elements.
This document discusses JavaScript functions and closures. It covers function syntax, arguments, context, and closures. Functions are the building blocks of JavaScript and can be declared in multiple ways. Functions are first-class objects that can be passed as arguments, assigned to variables, and returned from other functions. Closures allow functions to access variables from the scope in which they were declared even after that scope has closed. The most common misunderstanding with closures is that they store references to variables rather than copies.
The Ring programming language version 1.9 book - Part 90 of 210Mahmoud Samir Fayed
This document provides documentation on low-level functions in Ring that give access to the Ring virtual machine and runtime system. It describes functions for garbage collection, pointers, memory allocation, querying lists of functions, classes, packages, and more. It also covers functions for tracing, debugging, and interacting with the Ring VM.
The document discusses stacks and queues as data structures. It begins by defining a Node struct and List class to implement a linked list. It then provides an overview of stacks, including common stack operations like push and pop. Stacks follow LIFO order and can be implemented using arrays or linked lists. The document also discusses queue operations like enqueue and dequeue. Queues follow FIFO order and can also be implemented using arrays or linked lists. It provides examples of implementing both stacks and queues as classes with the appropriate member functions.
Functions allow code to be reused by defining formulas that can be called from different parts of a program. Functions take in inputs, perform operations, and return outputs. They are defined outside of the main body with a function prototype, and can be called multiple times from within main or other functions. This document demonstrates how to define a FindMax function that takes in two numbers, compares them, and returns the maximum number. It shows function prototypes, defining the function outside of main, and calling the function from within main to find the maximum of two user-input numbers.
The document discusses exception handling in Java. It provides examples of different types of exceptions like RuntimeException, Exception, and Error. It also covers try-catch blocks for exception handling, custom exceptions, and logging exceptions. Finally, it discusses exception handling best practices like checking for null before calling methods.
The document shows how to perform polynomial regression in Python and R. It imports data on position level and salary. Linear and polynomial regression models are fit to predict salary from position level. Visualizations are created to compare the linear and polynomial regression fits and predictions. Polynomial regression fits the data better by capturing the nonlinear relationship between position level and salary.
This document discusses JavaScript functions and function methods. It explains function.length to get the number of expected arguments, .call() and .apply() to call a function with a set this value and arguments, arguments.callee to access the currently executing function, .bind() to set the this value and bind arguments when calling a function. Examples are given to demonstrate these function methods.
The Ring programming language version 1.2 book - Part 57 of 84Mahmoud Samir Fayed
The document provides documentation for Ring, an open source programming language. It summarizes functions for extending the Ring virtual machine using C/C++. Key functions described include ring_ext.h for defining extension modules, ring_ext.c for loading the modules, and ring_vm_funcregister for registering C functions in Ring. Extension modules are organized with include files, registration functions, and following the Ring API for parameter checking and returning values.

This document provides an overview and introduction to building a basic fraction calculator app in Objective-C. It begins with an overview of the project architecture using the MVC pattern with a Fraction model class to represent fractions, a Calculator class to perform operations, and a ViewController class to manage the user interface. It then details the implementation of each class, including the Fraction class with methods for creating, modifying, and performing operations on fractions, the Calculator class for setting operands and performing operations, and the ViewController class for handling user interface events and updating the display.
This document discusses metaprogramming in C++ and describes an RPC framework implemented using C++ templates and metaprogramming. It defines an interface called calc_interface for a calculator RPC with functions like add and signals like expr_evaluated. It shows how to define the interface using meta_functions, and how a client can invoke functions on the server while handling serialization, transport, and response deserialization. Key aspects covered include defining the interface, invoking functions from the client, argument checking, and verifying functions exist in the interface.
The document summarizes new features in C# 4.0 including optional and named parameters, dynamic typing, tuples, complex numbers, parallel programming, and thread-safe data structures. It also mentions code contracts, memory-mapped files, and the Managed Extensibility Framework.
The document discusses using plain JDBC versus Spring's JdbcTemplate and other data access classes to simplify JDBC coding. It covers querying for single/multiple rows, binding variables, mapping rows to objects, batching, and callbacks. Spring's classes handle exception handling, closing resources, and simplify common data access tasks compared to plain JDBC.
The document discusses class and object-oriented programming concepts such as classes, objects, member functions, and constructors. It provides examples of class declarations and definitions, and how to create objects and call member functions. The document also covers constructors, initializer lists, destructors, function templates, and class templates.
Classes allow programmers to create new types that model real-world objects. A class defines both data attributes and built-in operations that can operate on that data. C++ provides built-in classes like string and iostream that add powerful functionality to the language. The string class allows easy storage and manipulation of strings, while the iostream classes (istream and ostream) define objects like cin and cout for input/output. These classes provide many useful built-in operations that make input/output powerful yet easy to use.

The document discusses strategies for developing sustainable mobile services, including focusing on one core service or developing a portfolio of services. It emphasizes the importance of driving traffic, retaining users over time through non-essential apps and gamification, and monetizing services through various business models like in-app billing. A portfolio approach requires combining apps thematically and leveraging synergies between apps to boost retention across the portfolio rather than for individual short-lived apps.
Plask Mobile aims to provide sustainable mobile services. It currently offers one main service but is considering expanding its portfolio. To be sustainable, Plask Mobile's strategies must consider target markets, market sizes, volatility risks, and goals around either maintaining its core service or pursuing synergies through diversification. Maintaining a clear focus on one service allows Plask Mobile to be the best player, while a portfolio approach could provide strategic advantages through synergies if risks are properly managed.

1. Controls Life Cycle
Example
result Devmento ::OnInitializing(void) { result Devmento::OnTerminating(void) {
result r = E_SUCCESS; result r = E_SUCCESS;
delete pPopup;
__pPopup = new Popup(); return r;
Dimension dim(300, 400); }
__pPopup->Construct(true, dim);
__pPopup->SetTitleText(L"Popup Test");
Button* pBtnClose = new Button();
pBtnClose->Construct(Rectangle(10, 10, 250, 60),
L"Close");
pBtnClose->SetActionId(ID_BUTTON_CLOSE_POPUP);
pBtnClose->AddActionEventListener(*this);
__pPopup->AddControl(*pBtnClose);
}
4. Collection
1. Object-based collections에서 스택 변수를 사용 말자.
ArrayList* pDataList = new ArrayList();
pDataList->Construct();
String aData(L”Test”);
pDataList.Add(aData);
String* aData= new String(L”Test”);
pDataList->Add(*aData);
5. Collection
1. 꼭 Remove 관련 함수 호출 시 속성을 꼭 true로 하자.
result Remove(const Object&obj,bool deallocate=false);
result RemoveAt(int index, bool deallocate = false);
Void RemoveAll(bool deallocate = false);
Object에 대한 메모리 해체 원한다면,
Remove(10); -> Remove(10,true);
6. Collection
2. 꼭 Remove 관련 함수 호출 시 속성을 꼭 true로 하자.
ArrayList* pDataList = new ArrayList();
pDataList->Construct();
String* pData = new String(L"url:1234567890");
pDataList->Add(*pData);
pDataList->RemoveAll(true);
delete pDataList;
7. Collection
3. Template-based collections
ArrayListT<int> list;
list.Construct();
int int1 = 1;
int int2 = 2;
list.Add(int1);
list.Add(int2);
