In C, does (x==y==z) behave as I'd expect?
c, equality
Solution
No, it does not.
`x == y` is converted to int, yields `0` or `1`, and the result is compared to `z`. So `x==y==z` will yield true if and only if `(x is equal to y and z is 1) or (x is not equal to y and z is 0)`
What you want to do is
if(x == y && x == z)
Problem
Can I compare three variables like the following, instead of doing `if((x==y)&&(y==z)&&(z=x))`? [The if statement should execute if all three variables have the same value. These are booleans.] ``` if(debounceATnow == debounceATlast == debounceATlastlast) { debounceANew = debounceATnow; } else { debounceANew = debounceAOld; } ```
