Show 例子

下表显示了C＃支持的所有算术运算符。 假设变量A保持10，变量B保持20，则 -

操作者	描述	例
+	添加两个操作数	A + B = 30
-	从第一个减去第二个操作数	A - B = -10
*	将两个操作数相乘	A * B = 200
/	Divides numerator by de-numerator	B/A = 2
%	模数运算符和整数除法后的余数	B％A = 0
++	递增运算符将整数值增加1	A ++ = 11
--	递减运算符将整数值减1	A-- = 9

例子 (Example)

以下示例演示了C＃中可用的所有算术运算符 -

using System;
namespace OperatorsAppl {
   class Program { 
      static void Main(string[] args) { 
         int a = 21;
         int b = 10;
         int c;
         c = a + b;
         Console.WriteLine("Line 1 - Value of c is {0}", c);
         c = a - b;
         Console.WriteLine("Line 2 - Value of c is {0}", c);
         c = a * b;
         Console.WriteLine("Line 3 - Value of c is {0}", c);
         c = a/b;
         Console.WriteLine("Line 4 - Value of c is {0}", c);
         c = a % b;
         Console.WriteLine("Line 5 - Value of c is {0}", c);
         c = a++;
         Console.WriteLine("Line 6 - Value of c is {0}", c);
         c = a--;
         Console.WriteLine("Line 7 - Value of c is {0}", c);
         Console.ReadLine();
      }
   }
}

编译并执行上述代码时，会产生以下结果 -

Line 1 - Value of c is 31
Line 2 - Value of c is 11
Line 3 - Value of c is 210
Line 4 - Value of c is 2
Line 5 - Value of c is 1
Line 6 - Value of c is 22
Line 7 - Value of c is 20
