Answer:
Loop header :- for(i=11;i<20;i+=2)
Explanation:
We want to find the product of odd integers between 10 and 50.Since 10 and 20 are even numbers we can exclude them and start the loop by 11 and end it on 19 and increasing the iterator i by 2 so that it is odd only .For example:- i=11 increasing by 2 then i = 13 which is odd.
