Recommended configuration for C++ programming using Eclipse on Linux

Title: Recommended configuration for using Eclipse for C programming on Linux

Introduction:
Eclipse, as a powerful integrated development environment (IDE), can provide C developers with convenience and efficiency programming environment. This article will introduce you to the recommended configuration for using Eclipse for C programming on Linux, and provide some practical code examples to help you better use Eclipse to develop C projects.

1. Install Eclipse:
First, we need to install Eclipse on the Linux system. You can download the latest C version from the Eclipse official website (https://www.eclipse.org/downloads/).

Generally speaking, use the following command to install on the Linux command line interface:

sudo apt-get install eclipse-cdt

After the installation is completed, you can find Eclipse in the startup menu or application list and run it.

2. Configure the Eclipse environment:

1. Set the workspace:
   When you run Eclipse for the first time, it will ask you to select a workspace, which is where you store your C projects Location. Choose an appropriate folder based on personal preference and make sure the workspace directory has appropriate read and write permissions.
2. Create a C project:
   Select "File" -> "New" -> "C Project" in the menu bar of Eclipse, and then follow the prompts to select the appropriate project name and project type. For example, selecting the "Executable" type will create an executable C project.
3. Configure the compiler:
   Eclipse uses the GNU Compiler Collection (GCC) as the C compiler by default, which can be found in "Project" -> "Properties" -> "C/C Build" to configure. Here you can set the path to the compiler, compilation options, etc.

Code example 1 - Hello World program:
The following is a simple Hello World program example:

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

Code example 2 - Addition calculator:
The following is A simple addition calculator example:

#include <iostream>

int main() {
    int num1, num2;
    std::cout << "Enter two numbers: ";
    std::cin >> num1 >> num2;
    int sum = num1 + num2;
    std::cout << "Sum is: " << sum << std::endl;
    return 0;
}

Note: The above code example can create a new C source file in the project, copy the code into the source file, and then proceed through the "Build" function of Eclipse Compile and run.

Conclusion:
With correct configuration and use of Eclipse, you can easily perform C programming on Linux. This article describes the installation and configuration process of Eclipse and provides two simple C code examples. I hope these contents can help you better use Eclipse for C project development. Happy coding!
