It's my first time asking for help here. When I try to compile the code I get the following errors. I'm using VS Code and sometimes, after a write more code, i get these errors. I have attached some screenshots with the two errors. I'm using C/C++: g++.exe when building my file.
The error in console:
Executing task: C/C++: g++.exe build active file
