how many times will strlen() be called in this for loop?

Question

Will the strlen() function below get called just once (with the value stored for further comparisons); or is it going to be called every time the comparison is performed?

Answer 1

strlen checks the lenght of the provided string. Which means that if the lenght is 10. Your iteration will keep on going as long as i is below 10.

And in that case. 10 times.
