运算符是一个符号，告诉编译器执行特定的数学或逻辑操作。
| 运算符 | 描述 | 例 |
|---|---|---|
| + | 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 |
| / | 将分子除以除分子 | B / A = 2 |
| ％ | 模运算符和整数除后的余数 | B％A = 0 |
| ++ | 增量运算符将整数值增加一 | A ++ = 11 |
| - | 减法运算符将整数值减一 | A-- = 9 |
让我们看一个在C#中使用算术运算符的示例。
示例
using System;
namespace Demo {
class Program {
static void Main(string[] args) {
int a = 99;
int b = 33;
int c;
c = a + b;
Console.WriteLine("Value of c is {0}", c);
c = a - b;
Console.WriteLine("Value of c is {0}", c);
c = a * b;
Console.WriteLine("Value of c is {0}", c);
c = a / b;
Console.WriteLine("Value of c is {0}", c);
c = a % b;
Console.WriteLine("Value of c is {0}", c);
c = a++;
Console.WriteLine("Value of c is {0}", c);
c = a--;
Console.WriteLine("Value of c is {0}", c);
Console.ReadLine();
}
}
}输出结果
Value of c is 132 Value of c is 66 Value of c is 3267 Value of c is 3 Value of c is 0 Value of c is 99 Value of c is 100
