1. Use Vscode to visualize c/c++ code tracking and debugging

1. Install Vscode

PS: The following is my own installation method. For more detailed reference, please refer to the tutorial on installing vscode under ubuntu18.04

1. Download the Vscode installation package on the official website

Download address portal

Choose .deb for Ubuntu

2. Copy the downloaded installation package to the virtual machine

code

4. Extension Installation
input code into the

input c ++, installation c / c ++ extensions

2. Configure and debug the c/c++ environment of Vscode

Create test.c file

touch test.c
gedit test.c

The test.c code is as follows:

#include<stdio.h>
int main()
{
    
      
  printf("hello world\n");
  return 0;
}

Click F5 to debug (generate launch.json, tasks.json files)

launch.json is as follows:

"version": "0.2.0",
    "configurations": [
        {
    
    
            "name": "gcc - 生成和调试活动文件",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}",
            "args": [],
            "stopAtEntry": false,   //选为true则会在打开控制台后停滞，暂时不执行程序
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,  //true为使用外部工作台，会额外打开一个终端显示程序运行结果，false使用vscode自带的工作台
            "MIMode": "gdb",
            "setupCommands": [
                {
    
    
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "C/C++: gcc build active file",
            "miDebuggerPath": "/usr/bin/gdb"
        }
    ]
}

tasks.json is as follows:

{
    
    
    "tasks": [
        {
    
    
            "type": "cppbuild",   //配置为cppbuild将会生成的文件放到根目录下，而改为shell会生成到当前目录下
            "label": "C/C++: gcc build active file",
            "command": "/usr/bin/gcc",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}/${fileBasenameNoExtension}"
            ],
            "options": {
    
    
                "cwd": "/usr/bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
    
    
                "kind": "build",
                "isDefault": true
            },
            "detail": "Generated task by Debugger"
        }
    ],
    "version": "2.0.0"
}

You can see that launch.json and tasks.json generally do not need to be changed. If the program needs it, you can change the cppbuild in tasks.json to shell

. 3. Configure the components and draw the circuit diagram.
Three components are needed. The resistance of the resistor needs to be reset, about 50 ohms.
