we think that Logical AND and Logical OR Operators have the same order of precedence. However, Logical AND has a higher preference than Logical OR operator. Thus, the Logical AND operator will be evaluated first and then the Logical OR operator will be evaluated if they exist in the ...
Great care must be taken in observing the correct operator precedence in such situations. ■ Vectors in a logical expression must all be the same size. ■ If a logical expression is a vector or a matrix, it is considered true in an if statement only if all its elements are non-zero. ...
When mixing logical AND and logical OR in the same expression, it is a good idea to explicitly parenthesize each operator and its operands. This helps prevent precedence mistakes, makes your code easier to read, and clearly defines how you intended the expression to evaluate. For example, ...
Logical operators work with all data types and return a Logical value. The following table lists the logical operators in order of precedence.Logical Operators展开表 OperatorActionCode 复制 ( ) Expression groups 复制 cVar AND (cVar2 AND cVAR3) 复制 NOT, ! Logical negative 复制 IF NOT cVar...
Logical OR (||) operator in CLogical OR is denoted by double pipe characters (||), it is used to check the combinations of more than one conditions; it is a binary operator – which requires two operands.If any of the operand's values is non-zero (true), Logical OR (||) operator...

因为operator<<比operator&&的precedence更高,所以std::cout << true && false;与(std::cout << true) && false;是相同的(即首先打印出true,然后将返回的std::cout转换为bool,它与false一起用作operator&&的操作数,最后将结果丢弃)。 请注意,std::cout可以通过operator bool转换为bool,即使它被标记为explicit...
(See the -qxlf77 option in the IBM Open XL Fortran Compiler Reference for details.) Otherwise, it is treated as a defined operator. If it is treated as an intrinsic operator, it can also be extended by a generic interface. The precedence of the operators determines the order of ...
