c 运算符##

Relational operators are used to compare the values and returns Boolean values, if condition is true – they return True, otherwise they return False.

关系运算符用于比较值并返回布尔值(如果condition为true)-它们返回True ，否则返回False 。

Here is the list of relation operators,

这是关系运算符的列表，

1. "==" (Equal To) – it returns true, if both operand’s values are equal

   “ ==”(等于) –如果两个操作数的值相等，则返回true

2. "!=" (Not Equal To) – it returns true, if both operand’s values are not equal

   “！=”(不等于) –如果两个操作数的值都不相等，则返回true

3. " – it returns true if first, operand is less than second operand

   “ –如果第一个操作数小于第二个操作数，则返回true

4. "<=" (Less Than or Equal To) – it returns true, if either first operand is less than or equal to second operand

   “ <=”(小于或等于) –如果第一个操作数小于或等于第二个操作数，则返回true

5. ">" (Greater Than) – it returns true, if first operand is greater than second operand

   “>”(大于) –如果第一个操作数大于第二个操作数，则返回true

6. ">=" (Greater Than or Equal To) – it returns true, if either first operand is greater than or equal to second operand

   “> =”(大于或等于) –如果第一个操作数大于或等于第二个操作数，则返回true

Syntax:

句法：

    Operand1 == Operand2
Operand1 != Operand2
Operand1 < Operand2
Operand1 <= Operand2
Operand1 > Operand2
Operand1 >= Operand2

Example:

例：

    Input:
int a = 10;
int b = 3;
Console.WriteLine("a==b: {0}", (a == b));
Console.WriteLine("a!=b: {0}", (a != b));
Console.WriteLine("a>b : {0}", (a > b));
Console.WriteLine("a>=b: {0}", (a >= b));
Console.WriteLine("a<b : {0}", (a < b));
Console.WriteLine("a<=b: {0}", (a <= b));
Output:
a==b: False
a!=b: True
a>b : True
a>=b: True
a<b : False
a<=b: False
