[Solved] C++: Why does this logical expression evaluate to false? [closed]

Question

The inner expression:

(a < 5) || (c < (a + b))

evaluates a < 5 as false (since a is 10) and c < (a + b) as true (since 8 is less than 10+12). Performing a Boolean “or” operation on false and true gives you true.

And, given that the next thing you do to that value is the ! (inversion), that true turns into a false.
