There are three major steps that you must follow: 1) Create a C++ Project 2) Write the Source Code 3) Build and Run the Application The steps below will show you have to create a helloworld application. Step 1: Select Workspace folder, i.e. where you will store your projects. Click the OK button after you have selected a folder. Figure 10: Step 1 Develop HelloWorld Application in Eclipse

15 Page 15 of 19 Step 2: Close the Welcome Screen. Do this by clicking on the X next to the Welcome tab Figure 11: Step 2 Develop HelloWorld Application in Eclipse Step 3: Create a new Project by selecting: File -> New -> Other Figure 12: Step 3 Develop HelloWorld Application in Eclipse

16 Page 16 of 19 Step 4: Select C/C++ -> C++ Project and then click the Next Button. Figure 13: Step 4 Develop HelloWorld Application in Eclipse Step 5: First give your project a name, then select Executable -> Hello World C++ Project and then click the Next Button.
