Exit
Learn Exit in Fortran through a focused explanation, a dedicated topic-specific example, an engineering boundary, and a mastery check.
Exit is a focused Fortran lesson inside Control Flow. The example uses the construct named in the lesson directly rather than reusing a generic placeholder.
Trace the example from its inputs through Exit and identify the behavior that would change if that construct were removed or replaced. Pay attention to the language-specific rules shown by the syntax, because neighboring lessons intentionally exercise different mechanisms.
Topic-specific example
program demo
implicit none
integer :: values(3) = [27, 28, 29]
print *, sum(values) ! Exit
end program demo
For Exit, test one realistic boundary: empty data, invalid input, unavailable resources, lifetime/cleanup, type constraints, or concurrency timing where applicable. A successful happy path is not enough to prove the construct is used correctly.
