In Ubuntu 16.04, how does one debug the C language program with a breakpoint?

Problem: The environment is Ubuntu16.04. How to Use Vscode breakpoint to debug C language programs.

Writing code without a debugging environment is intolerable, so I finally succeeded. The tossing process is as follows:

1. First install the C/C ++ extension. Search for the first extension directly. Or click this link to view its help documentation for installation.

2. Open the current project directory, click debug options on the left, and click Add configuration to generate a launch. json file with the following content:

{
// Use intelliisense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink? Linkid = 830387
"Version": "0.2.0 ",
"Deployments ":[
{
"Name": "(gdb) Launch ",
"Type": "cppdbg ",
"Request": "launch ",
"Program": "$ {workspaceFolder}/LearnC/bin/a. out ",
"Args": [],
"StopAtEntry": false,
"Cwd": "$ {workspaceFolder }",
"Environment": [],
"ExternalConsole": true,
"MIMode": "gdb ",
"SetupCommands ":[
{
"Description": "Enable pretty-printing for gdb ",
"Text": "-enable-pretty-printing ",
"IgnoreFailures": true
}
]
}]
}

All content is generated by default. I only modified the "program" line and specified it as an executable file after compilation. In this way, this file is debugged by default during debugging.

Select add configuration

Select C ++ (GDB/LLDB)

3. Edit the code. Compile the code first. The command is as follows:

$ Gcc-g-o/path/LearnC/bin/a. out [[SOURCE_FILE]

The first path specifies the generated file. It must be the file path specified by the previous program parameter. SOURCE_FILE indicates the C language file path.

4. Enable debugging. My shortcut key is F5. After opening it, You can directly run it at the breakpoint. The effect is as follows:
