Storing objects is an integral element to have a functioning object oriented program. This can require a lot of research and reading, so here are some tutorials to help you along the way with your C++ development. Take time to read these and get yourself knowledgeable on this subject.
Velocity Reviews> Newsgroups> Programming> C++ > How to store an object and reuse it later in C++ Posts: n/a. 01-11-2004. I have an object and want to store it in a file. Then later I can read. in the object and obtain all the info in it. How can I do this ? Thanks a lot. Posts: n/a. 01-11-2004.
The CryptographicHash object can be used to repeatedly hash different data without having to re-create the object for each use. The Append method adds new data to a buffer to be hashed. The GetValueAndReset method hashes the data and resets the object for another use. This is shown by the following example.
Improve performance and memory use by reusing objects from a fixed pool instead of allocating and freeing them individually. We’re working on the visual effects for our game. When the hero casts a spell, we want a shimmer of sparkles to burst across the screen. This calls for a particle system: an engine that spawns little sparkly graphics and animates them until they wink out of existence.
It's interesting how the term "functor" means completely different things in various programming languages. Take C++ for example. Everyone who has mastered C++ knows that you call a class that implements operator() a functor. Now take Standard ML. In ML functors are mappings from structures to structures.
Part of C++ FQA Lite. To see the original answers, follow the FAQ links. This page is about C++ references - a duplicate language feature introduced in order to support other duplicate features. [8.1] What is a reference? FAQ: It's an alias for an object - another name by which it can be called.
Using C++ code from within a Java application, and calling from C++ to a Java object. This article explores some of the issues involved in integrating C++ code into a Java program. It shows how to call from a Java object to a C++ object, and how to call from a C++ object to a Java object. Issues such as interaction with garbage collection are explored, and a simple framework for integrating Java and C++ is developed.
Peter Müller. firstname.lastname@example.org. Globewide Network Academy (GNA) www.gnacademy.org/ September 4, 1997 The first course Object-Oriented Programming Using C++ was held in Summer 1994 and was based on a simple ASCII tutorial. After a call for participation, several highly motivated people from all over the world joined course coordinator Marcus Speh as consultants and had pushed the course to its success.
This is a video recorded for the semester in Fall 2008 for ECE 462.
Here are key resources to help you get started with using C++ (including Visual C++ component extensions (C++/CX)) to develop Windows Store apps. This is not a comprehensive list of all of the features or available resources. Some topics listed below are specific to C++, and some are not specific to any single programming language.
This is a quick summary of iterators in the Standard Template Library. For information on defining iterators for new containers, see here. Iterator: a pointer-like object that can be incremented with ++, dereferenced with *, and compared against another iterator with ! Iterators are generated by STL container member functions, such as begin() and end().
This is an incomplete survey of some of the generic programming techniques used in the boost libraries. Table of Contents. Generic programming is about generalizing software components so that they can be easily reused in a wide variety of situations. In C++, class and function templates are particularly effective mechanisms for generic programming because they make the generalization possible without sacrificing efficiency.
Back to C++ Optimization Techniques. 4: C++ Final Optimizations. Your application is up and running. The data structures are ideal, the algorithms sublime, the code elegant, but the app - well, it's not quite living up to its potential. Time to get drastic, and with drastic measures, there are tradeoffs to consider.
Saving complex object data to a file. Davitosan (34) I was trying to create a file where object data could be written, so that different programs could use it. I'm having trouble understanding just exactly what goes on when a program writes to a file, so I hope somebody could help me out. First, this program saves an object of the class "Something" to a file:
First of all I would like to thank to Martyr2 for some guidance. In this tutorial, I will show how to store class objects in vector just like making a linked list using the STL. A conventional linked list is a structure of data that is linked together using the struct or class keywords. Overview of Linked List.
