C＃-算術演算子

次の表は、C＃でサポートされているすべての算術演算子を示しています。 変数 A が10を保持し、変数 B が20を保持すると仮定します-

Operator	Description	Example
+	Adds two operands	A + B = 30
-	Subtracts second operand from the first	A - B = -10
*	Multiplies both operands	A* B = 200
/	Divides numerator by de-numerator	B/A = 2
%	Modulus Operator and remainder of after an integer division	B % A = 0
++	Increment operator increases integer value by one	A++ = 11
—	Decrement operator decreases integer value by one	A-- = 9

例

次の例は、C＃で使用可能なすべての算術演算子を示しています-

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();
      }
   }
}

上記のコードをコンパイルして実行すると、次の結果が生成されます-

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
