Help needed in understanding how to set up C++ on my Mac

[112Butter]

I've been trying to start learning how to program on C++.
I tried all kinds of instructions on how to set it up using Visual Code, yet I don't seem to get anywhere, and I feel like I'm about to lose it after working on it for 8 hours. :(

Currently I'm following the instruction on https://code.visualstudio.com/docs/cpp/config-clang-mac.
After getting to the step [Run helloworld.cpp], 4. I seem to get stuck.
I'm getting the error message "expected ';' at end of declaration ggc[row 9, column 23]"

My tasks.json file does also look completely different:
{
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: clang++ Aktive Datei kompilieren",
"command": "/usr/bin/clang++",
"args": [
"-fcolor-diagnostics",
"-fansi-escape-codes",
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "Vom Debugger generierte Aufgabe."
}
],
"version": "2.0.0"
}

I want to set it up to be able to follow the tutorial https://www.youtube.com/watch?v=8jLOx1hD3_o&t=5508s, which is supposed to be a good course in understanding the basics, but I feel like I need 31 hours to just set C++ up.

I hope I gave all the information that is needed to help me with my issue. If not, I definitely don't mind answering any questions.
Any help would be extremely appreciated!!

Can you add "-std=c++17", to your args list? See https://code.visualstudio.com/docs/cpp/config-clang-mac#_troubleshooting
