Sometimes testing for zero makes sense. When you write code, you are
telling a story. If you are talking about zero as a number then it
can make sense. If it's zero as a boolean then it doesn't make sense.
Also strcmp() and similar should always be done as == 0, < 0 or != 0
because that is the idiom:
if name != "foo" then
becomes:
if (strcmpt(name, "foo") != 0) {
The != from the first is shifted in the second.
So I don't really think this approach is the right thing. You have to
read the code and understand the story it is telling. Then change it
if needed.
