And Make It Better

and make it better represents a topic that has garnered significant attention and interest. What is the difference between the | and || or operators?. I have always used || (two pipes) in OR expressions, both in C# and PHP. Occasionally I see a single pipe used: |. What is the difference between those two usages? Building on this, are there any caveats when using ...

What is Python's equivalent of && (logical-and) in an if-statement?. There is no bitwise negation in Python (just the bitwise inverse operator ~ - but that is not equivalent to not). Unary arithmetic and bitwise/binary operations and 6.7. Another key aspect involves, binary arithmetic operations. The logical operators (like in many other languages) have the advantage that these are short-circuited.

That means if the first operand already defines the result, then the second ... Difference between & and && in C? Furthermore, the & operator performs a bit-wise and operation on its integer operands, producing an integer result. Thus (8 & 4) is (0b00001000 bitand 0b00000100) (using a binary notation that does not exist in standard C, for clarity), which results in 0b00000000 or 0.

The && operator performs a logical and operation on its boolean operands, producing a boolean result. Thus (8 && 4) is equivalent to ((8 ... What is the difference between "++" and "+= 1 " operators?. @leftaroundabout: Integers and iterators have nothing to do with one another.

We aren't talking about pointers here (and the proper generalization of i += 1 would be std::advance (i, 1)), and the OP seems not yet knowledgeable enough to complicate matters in such a way. I stand by my point: the only difference between i += 1 and ++i for integers (which is what is asked about) is a cosmetic one. Difference between Boolean operators && and & and between || and | in R. According to the R language definition, the difference between & and && (correspondingly | and ||) is that the former is vectorized while the latter is not. According to the help text, I

Logical operators ("and", "or") in Windows batch - Stack Overflow. Similarly, how would you implement logical operators in Windows batch files? AND OR order of operations - Stack Overflow.

In the normal set of boolean connectives (from a logic standpoint), and is higher-precedence than or, so A or B and C is really A or (B and C). Wikipedia lists them in-order. Most programming languages should obey this convention unless they are really weird. That said, for your particular language or environment it should be possible to concoct a very small test to satisfy yourself that it is ...
