for loop

the third part of the for loop is the iteration, i just wanted to know in the above code does the line 3 evaluates the output or its just that the iteration starts after the condition is passed.

i tried running without line 3 and the result is never ending, so how does the condition operator gets checked and starts the iteration.

This is the condition.

1) set a to 1.
2) Check if b is equal to 1.
3) enter the loop and process it.
4) finish off the third part of the iteration i.e print.

For the next run, a is still 1 while b is 2 ( due to b=b-a). This will print once more.

For the third run, a =1 and b is 1 too. the condition fails and the loop exits.
