HelloWorld: -writes “Hello World!” to the console

Description

HelloWorld is a very -simple piece of code showing how text is written to the console. All other -examples in Basics and System use -the same technique.

The file CommonFramework.h contains -the entry point and all code necessary to support the example itself, including -the construction of the console and the cleanup stack. Putting code into a .h file -may not be conventional practice, but it is useful to do so here.

Download

Click on the following link to download -the example: HelloWorld.zip

Download some additional files -required by the example: CommonFramework.zip.

Click browse to view the example code.

Build

The example includes the two project files -needed for building: bld.inf and the .mmp file.

The Symbian platform build -process describes how to build this application, which results in an -executable called:

\epoc32\release\<target>\<urel -or udeb>\HELLOWORLD.EXE.

Usage

Run the executable HELLOWORLD.EXE.

Executables -for the emulator targets wins and winscw can -be run on your PC. Executables for ARM targets must be copied to your target -platform before being run.

Classes used

The example shows the use of the _LIT macro -which is used throughout all of the examples. The macro generates a:

const static TLitC<TInt>

object -and is an efficient and convenient way of generating constant literal text.

As -this is a wide (Unicode) build, TLItC<TInt> is a typedef -for TLitC16<TInt>.
