The following is the text of this article, reference: Station B: Goose bomb

1. How to install vscode?

Second, the compilation process

1. Create a workspace

The code is as follows (enter in the terminal):
Find the folder you want to put, open the terminal, and enter the following code.

mkdir EIGEN
code ./EIGEN

Get this workspace.

Install plugin: C++

2. C++ debugging

Create a .cpp file (note: the file type is related to the file name suffix).

Just write a C++ program

#include<iostream>
#include<string>
using namespace std;
int main(int argc,char **argv )
{
    
    
    cout<<"hello ltt"<<endl;
    return 0;
}

Create launch.json file

Environment selection: C++ (GDB/LLDB)

Then select g++ build and debug active file to get the .json file.

Create the task.json file (sequentially)
1. Go back to the .cpp file
2. ctrl+shift+p or F1 to open the command bar
3.tasks: Configure Task
4.C/ C++: g++ build active file
5. Get the result shown in the figure below

Join in the tasks.json file

"-std=c++17"

The location is as follows.

Then return to the cpp file and add a breakpoint. F5 runs.

Add an option in the launch.json file

 "internalConsoleOptions": "neverOpen",

In the blue position in the figure below:

return to find that the debugging is successful;
