Assignment operatorsThe PHP assignment operator is used to write values to variables. The base assignment operator in PHP is "=".This means that the right-hand copy expression sets the value for the left-hand operand._________________________________
One of the most basic uses of computers is to perform mathematical operations, and as a computer language, Java also provides a rich set of operators to manipulate variables. We can divide the operators into the following groups:
Arithmetic
Precautions:
Constants are assigned at compile time, and variables are allocated in memory when they are run.
Assignment operator + =-+ *+%= \= The Java compiler enforces type conversions
Residual:In Java, it is time to take the
Logical AND logical OR logical is not a Boolean worthwhile operation, it belongs to the discrete mathematics category.bitwise AND, bitwise OR, bitwise is not the operation of the computer bit, belongs to the computer bits operation category.Logic
In this article, let's take a look at the objective-c bitwise operator . There are various operators in the objective-c language to handle the special positioning in numbers, as shown in the following table:
Symbol
Operation
Logical operators:Logic and:&&Logical OR: | |Logical non-:!Note: Logic and logic or the use of short-circuit methods. From left to right, if the determined value is no longer evaluated.Eg:boolean c =1>2 && 2> (3/0); && does not report abnormal
Language bitwise operators: With, OR, XOR, reverse, move left, and rightA bitwise operation is a binary-based operation. In system software, it is often necessary to deal with bits problems. The C language provides 6 bit manipulation operators.

Bitwise operations are operations that are performed in binary order. In system software, it is often necessary to deal with bits problems. The C language provides 6 bit operator operators. These operators can only be used for integer operands, that
