4.0 Errors 1-10

An error is a problem that occurs when the program is running.
There are two types of errors: syntax errors and runtime errors.
Syntax errors are caught before the code is ran, these can not be catched by the user.
Runtime errors are caught while the code is running, these can be catched by the user.
And uncaught error will cause the program to safely exit.
The exit code then is set to the error code.
In most cases a helpful error message is printed to the console, also showing where the error occured.
When no error occured, the program will always exit with exit code 0.

If the program crashes without printing an error message, it is most likely a bug and should be reported.
If the error location is wrong or the error message is not correct, it is most likely a bug and should be reported.
