In c#: what is the operator?

In C#, operators are symbols that perform operations on variables, including: Arithmetic operators: perform mathematical operations such as addition, subtraction, multiplication, and division. Relational operators: Compare two expression values, such as equal to, not equal to, greater than, and less than. Logical operators: perform logical operations on Boolean values, such as AND or XOR. Bit operators: perform operations on binary bits, such as AND, XOR, left shift and right shift.

Operators in C

#Operators are special symbols used to perform operations on variables and values. In C#, there are various types of operators used to perform arithmetic, relational, logical and bitwise operations.

Arithmetic operators

Arithmetic operators are used to perform mathematical operations on numbers. They include:

• Addition()
• Subtraction(-)
• Multiplication(*)
• Division(/)
• Modulo operation (%)

Relational operator

Relational operator is used to compare the values ​​of two expressions. They include:

• Equal to (==)
• Not equal to (!=)
• Greater than (>)
• Less than (< )
• Greater than or equal to (>=)
• Less than or equal to (<=)

Logical operator

Logical operators are used to perform logical operations on Boolean values. They include:

• AND(&&)
• OR(||)
• XOR(^)
• NOT(!)

Bit operators

Bit operators are used to operate on binary bits. They include:

• and (&)
• or (|)
• XOR(^)
• left shift(<< )
• Shift right(>>)

Example

Here are some C# code examples using operators:

<code class="c#">// 算术运算
int sum = 10 + 20;
int difference = 20 - 10;

// 关系运算
bool isEqualTo = (10 == 20);
bool isLessThan = (10 < 20);

// 逻辑运算
bool logicalAnd = (10 > 5 && 20 < 30);
bool logicalOr = (10 < 5 || 20 > 30);</code>
