Lab 1#

Task 1 Install WSL#

install wsl

wsl --install

In this task,I fail to install wsl. So I do this :

wsl -l -o
wsl --install -d Ubuntu-20.04

That’s my successful examples.

DISM.exe /Online /Enable-Feature /FeatureName:VirtualMachinePlatform /All /NoRestart

use the bash to start the system:

wsl -l -v
wsl -d Ubuntu-24.04

the username and password is

I donnot update in the markdown = =

we see that the Ubuntu-24.04 has been installed.

sudo apt update
sudo apt install g++ -y

we use the commond to check their version up

gcc --version

Task 2 Use the WSL in visual studio code#

Open the vscode(Downloaded)

We use the Ctrl+Alt+O to command the system, and wait for a while to install the server of WSL

If the connection is successful you will see:

/mnt/d/Code/Cplusplus/SUST Cpp course/ is a file path, typically used in a Linux system to indicate a directory within a mounted Windows file system. Here’s a breakdown of its components:

• /mnt/d: In Linux, /mnt is a mount point directory commonly used for mounting external storage devices or partitions. /mnt/d indicates that the D drive from a Windows system is mounted here.

Task 3 Compile,Link and Run C/C++ Programs#

The step called Compile

We create the .exe post-name-file. The step called Linking

The default output executable file is called “a.exe”(Windows) or “a.out”(Unix and Mac OS) if you don’t specify the name in compiling and linking step.

You need to use g++ to compile C++ program. The -o option is used to specify the output file name.

Task 4 Terminal Output#

printf(format-control-string, other-arguments) format-control-string describes the output format, which consists of conversion specifiers, field widths, precisions and literal characters with percent sign(%).

Task 5 Execrise#

We couldnot directly compile the main.cpp if we only compile the main.cpp advoke g++ -o main main.cpp && ./main

1. 方法

   • 编译 add.cpp 文件生成对象文件：

     g++ -c add.cpp -o add.o

   • 编译 main.cpp 文件生成对象文件：

     g++ -c main.cpp -o main.o

   • 链接两个对象文件生成可执行文件：

     g++ main.o add.o -o myprogram.exe

     gcc -c add.cpp -o add.o
     gcc -c main.cpp -o main.o
     gcc main.o add.o -o myprogram -lstdc++

2. Cmake

• 步骤 1: 创建 CMakeLists.txt 文件

  在你的项目根目录下创建一个名为 CMakeLists.txt 的文件。这个文件将包含构建项目的指令。

  cmake_minimum_required(VERSION 3.10)
  
  # 项目名称
  project(MyProject)
  
  # 设置 C++ 标准
  set(CMAKE_CXX_STANDARD 11)
  set(CMAKE_CXX_STANDARD_REQUIRED True)
  
  # 添加源文件
  add_executable(myprogram main.cpp add.cpp)

• 步骤 2: 创建构建目录

  在项目根目录下创建一个名为 build 的目录，用于存放构建文件。

  mkdir build
  cd build

• 步骤 3: 运行 CMake

  在 build 目录中运行 cmake 命令，指定源代码目录。

  cmake

  这个命令会读取 CMakeLists.txt 文件，并生成适合你的系统的构建文件（如 Makefile 或 Visual Studio 解决方案文件）。

• 步骤 4: 编译项目

  使用生成的构建文件编译项目。

• 如果你使用的是 Makefile（通常是在 Unix-like 系统上）：

  make

• 如果你使用的是 Visual Studio（在 Windows 上）：

  打开生成的解决方案文件，并在 Visual Studio 中构建项目。
