C++ Group

Welcome Guest!

This page is the C++ Group home page (summary page).

C++

C++ group focusing promarily on generic C++ and C++.Net (C++/CLI) as implemented in Microsoft Visual C++. Whenever possible, this group also touches on C++Builder as well as ISO C++98, ISO C++03, C++/CLI (ECMA-372), the upcoming C++0x (probably C++09), an

Introduced as a "high level assembler," C was engineered to be "close to the metal."  It was also designed to be terse, elegant and expressive.  C was rapidly embraced by "real" programmers.

Not satisfied with its procedural-only model, C++ soon emerged to add object orientation to C.  In "computer years," these languages are mature - yet remain popular and viable languages for development. Many of the syntax and style elements of C and C++ made their way into younger languages, like Java, JavaScript and C#.

Want to become a moderator?
We are currently looking for moderators for our C++ message board. We are looking for knowledgable developers in Generic C, Generic C++, C++Builder, and Visual C++. However, if you're an expert in another C++ tool, we'd love to add your skillset to our group. If you're interested, send a private message to Mike Prestwood. Once you are a moderator, you will receive an email whenever someone posts.

Want to become an author?
We are currently looking for authors to post to this group's knowledge base. We are looking for generic C and C++ material as well as material specific to C++Builder and Visual C++. If you're interested, send a private message to Mike Prestwood or get started by submitting content to our C++ KB Topic (or any subtopic).

Week 35, Posted Monday 8/30/2010

Content changes every Monday @ 1AM!! Check back once per week. Learn! Review! Test Yourself!

FAQ of the Week
Question: How do you comment code in C++?

Answer:

Use two forward slashes to represent a single line comment:

// This is a C++ style single line comment.

You can also use multiple line comments:

/*
This is a mutliple line comment. This
syntax is borrowed from C.
*/
 Tip of the Week
Tip:

In C and C++, it is better to only use unary operators for incrementing and decrementing variables because they produce fewer instructions and run faster.
Code Snippet of the Week
C++ Inheritance (: public ParentClass)

General Info: Inheritance

The concept of a class makes it possible to define subclasses that share some or all of the main class characteristics. This is called inheritance. Inheritance also allows you to reuse code more efficiently. In a class tree, inheritance is used to design classes vertically. (You can use Interfaces to design classes horizontally within a class tree.) With inheritance, you are defining an "is-a" relationship (i.e. a chow is-a dog). Analysts using UML call this generalization where you generalize specific classes into general parent classes.

C++ Inheritance

In C++ you use the class keyword to signify a class and a colon followed by the parent class name for inheritance.

In the following example, a terminator T-600 is-an android. 

class Android {
};

class T-600: Public Android {
};

C++/CLI Empty String Check (String.IsNullOrEmpty)

The .Net framework offers a static method in the string class: String.IsNullOrEmpty.

 
String^ s;
  
//s = ""; //Uncomment to test 2nd case.
  
if (String::IsNullOrEmpty(s))
{
  MessageBox::Show("empty string");
}
