for loop termination
Conditionals and loops example from a Well House Consultants training course
More on Conditionals and loops [link]
Source code: clumpit Module: U103
Although a for loop in a language like C or Perl tests the end
condition at every iteration, that does not happen in other languages
such as Fortran or Lua. In this Lua example, the for loop will run
eight times - k taking the values 1 4 7 10 13 16 19 and 22, even though
j will have become 14 by the time the loop finishes.
Note that in Lua, the end of the range is INCLUSIVE whereas in Python
it is EXCLUSIVE. In Ruby you have a choice, depending on whether you
use the .. or the ... operator.
You can use break to get out of any loop early, but there is no
continue statement in Lua.
j,z = 22,14
for k = 1, j, 3 do
j = j - 1
--[[ Sample output:
[trainee@easterton toweb]$ lua clumpit
