Question how to it fprintf the answer, i able to use display but i have not idea how to made it on fprintf?

[Walter Roberson]

Caution: you are not changing i within the loop, so every iteration is going to be adding exactly the same thing to the total.

hi Roberson,

I just did some edit on the script dose it correct?

when i run on display i able to get the total , when i try on fprintf it not working.

[Walter Roberson]

Rewriting in terms of index looks better.
