First, the PHP operator
PHP has a rich set of operators, most of which come directly from the C language. The operators can be divided into arithmetic operators, string operators, assignment operators, bitwise operators, conditional operators,
The following example shows you how to use a primary data type with a specific operator. Fundamentally, it is the same example that executes over and over again, using only a different main data type. The file compiles without an error, because the
Ruby supports a modern language of a rich array of operators. Most operators are actually method calls. For example, A + B is interpreted as a,
+ (b) The method of the object referenced by the variable is called a parameter with B as its.
The operators of Turbo C are very rich and fall into three main categories: arithmetic operators, relational operators and logical operators, bitwise operators. In addition, there are operators to accomplish special tasks. The following
A Boolean Logic operations
We know that variables of type bool have only two values, true and false, and mathematically 1 and 0. A lot of time to judge when a condition is set up to continue to execute, so that the conditional expression is

This is a brief introduction to
Bitwise operators allow us to manipulate a single "bit" in the primary data type of an integer, that is, bits. The bitwise operator performs a Boolean algebra on the corresponding bits in the two arguments and eventually produces a result.Bitwise
The previous section describes the bitwise operators in C + +, and this section continues to learn about other operators in C + +. To deepen the understanding of the various operators.
Self-、--self-reduction of 1.++
This operator can be divided
Chinese arithmetic operator
These jobs are similar to those taught in basic schools.

5.3 Bitwise Operators
The difference between Turbo C and other advanced languages is that it fully supports bitwise operators. This is somewhat similar to the bit operation of assembly language.
The bitwise operators in Turbo C are:
This article is not a simple translation of the English version of PHP.ini, but the reference to a large number of materials, combined with their own understanding,
On the basis of original php.ini, the configuration
C # is also regarded as halfway decent, the foundation is not very good, these days to learn a bit of the "C # Introductory Classic," is a cornerstone of the. The first three chapters have been read, today began to read the fourth chapter.
§1 C #
The shift operator is oriented to an Operation object that is also a binary "bit". You can use them individually to handle integer types (one of the main types). The left shift operator (>) assigns the Operation object to the left of the operator
Bitwise operators are operators that perform operations on data by bits. Bit operations are operations supported by many other languages, such as C, C + +, and Java, and C # is no exception to support bit operations. Note bit operations support data
4.5.1 annotation character (Annotation)Two types of annotation characters can be used in Transact-SQL.The ANSI standard annotation character "--" is used for single-line annotations;The same as the C language of the program annotation symbol, that
The Second, bit structure bit structure is a special structure that is more convenient than bitwise operators when you need to access multiple bits of a byte or word by bit. The general form of a bit structure definition is: struct the bit
We know that any information is stored in binary form in the computer. Bitwise operators are operators that operate on data in binary order. The bit operators in the C # language are:
^ XOR or
~ Take the Fill
>> Move Right
An operator symbol can be used to handle numbers, strings, and other conditions that require comparison operations. PHP's operational symbols and C language operation symbol and very similar, for experienced program designers,
