以下是一个简单的Python程序,实现了复数类Complex:
```python
class Complex:
def __init__(self, real, virtual):
self.real = real
self.virtual = virtual
def __add__(self, other):
return Complex(self.real + other.real, self.virtual + other.virtual)
def __sub__(self, other):
return Complex(self.real - other.real, self.virtual - other.virtual)
def __mul__(self, other):
return Complex(self.real * other.real - self.virtual * other.virtual,
self.real * other.virtual + self.virtual * other.real)
def __truediv__(self, other):
denominator = other.real**2 + other.virtual**2
return Complex((self.real * other.real + self.virtual * other.virtual) / denominator,
(self.virtual * other.real - self.real * other.virtual) / denominator)
def __str__(self):
return f"{self.real} + {self.virtual}i" if self.virtual >= 0 else f"{self.real} - {-self.virtual}i"
```
在这个程序中,我们使用了Python内置的魔法方法(magic method),通过重载加、减、乘、除等运算符,实现了复数的加减乘除。其中,`__init__`方法用于初始化复数的实部和虚部,`__str__`方法用于将复数对象转换为字符串输出。你可以使用以下代码测试:
```python
a = Complex(1, 2)
b = Complex(3, 4)
print(a + b)
print(a - b)
print(a * b)
print(a / b)
```
输出结果为:
```
4 + 6i
-2 - 2i
-5 + 10i
0.44 + 0.08i
```
