and find represents a topic that has garnered significant attention and interest. Logical operators ("and", "or") in Windows batch - Stack Overflow. How would you implement logical operators in Windows batch files? 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? In this context, are there any caveats when using ... Difference between & and && in C?
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 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.
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 ... Additionally, regular Expressions: Is there an AND operator? Obviously, you can use the | (pipe?) to represent OR, but is there a way to represent AND as well?
Specifically, I'd like to match paragraphs of text that contain ALL of a certain phrase, but in no 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 ...
Difference between Boolean operators && and & and between || and | in R. In this context, 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
What is the difference between "++" and "+= 1 " operators?.
