c 運算符##

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

關系運算符用于比較值并返回布爾值(如果condition為true)-它們返回True ，否則返回False 。

Here is the list of relation operators,

這是關系運算符的列表，

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

“ ==”(等于) –如果兩個操作數的值相等，則返回true

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

“！=”(不等于) –如果兩個操作數的值都不相等，則返回true

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

“ –如果第一個操作數小于第二個操作數，則返回true

"<=" (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) –如果第一個操作數小于或等于第二個操作數，則返回true

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

“>”(大于) –如果第一個操作數大于第二個操作數，則返回true

">=" (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) –如果第一個操作數大于或等于第二個操作數，則返回true

Syntax:

句法：

Operand1 == Operand2Operand1 != Operand2Operand1 < Operand2Operand1 <= Operand2Operand1 > Operand2Operand1 >= 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: Falsea!=b: Truea>b : Truea>=b: Truea<b : Falsea<=b: False
