greater significance of a "logic short circuit" is that it can reduce the level of logical judgment in some cases (the premise of a condition before a condition is judged). For example, if we want to use the member variable of a struct pointer as a condition, we must first determine whether the struct pointer is valid, then we can judge the pointer's member variable. Without a "logic short" mechanism, our code should be written as:human* p = nullptr; ..... if (nullptr! = p)// first determine i
