this will run for i=1 to i=3
So 3 times.

The way 'for' executes is:
First the initialisation (i=1)
Then test - if false exit - don't execute body
Then loop body.
Then increment (i++)
Loop back to the test.
So, where the test applies, on the first pass, i=1, then i=2, then i=3 then i=4 - fail don't execute body.
So the body executes three times for the example as given.
