If you find that your settings.json already has some lines there, make sure you add a , after the last line before entering the text from this lesson or setting changes may not work.
For example you may see this:
{
"C_Cpp.updateChannel": "Insiders",
"files.autoSave": "off",
"editor.fontSize": 18
}
You’ll need to add a , after the 18 then paste the extra code:
{
"C_Cpp.updateChannel": "Insiders",
"files.autoSave": "off",
"editor.fontSize": 18,
"terminal.integrated.shell.windows": "cmd.exe",
"terminal.integrated.shellArgs.windows": [
"/k", "C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\BuildTools\\Common7\\Tools\\VsDevCmd.bat"
]
}
