for loop question [DONE]

[nilsener]

Dear,

i am always unsure if this loop will be executed 3 or 4 times?

[jacqueskleynhans]

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.
