In second sentence I replaced [size=150]having to use[/size] with using. Does it give same sense ? If yes, what is the mean of using having in first sentence?
“without having to use” means “without needing to use” or “without being required to use”. In this case, because of the overall context of the sentence, there is not a great deal of difference between “having to use” and “using”.
