How to compare multiple variables in an if statement?

Question

I have multiple variables:

1. var1
2. var2
3. var3

How can I check if any of the variables is less than 0, in one single line of code without separating it into 3 if statements?

Answer 1

It sounds like you mean OR:

if (var1 < 0 || var2 < 0 || var3 < 0) {
    ...
}

Answer 2

if (var1 < 0 || var2 < 0 || var3 < 0) {
}
