分别输入2个复数的实部与虚部，用函数实现计算2个复数之和与之积。 若2个复数分别为：c1=x1+(y1)i, c2=x2+(y2)i， 则： c1+c2 = (x1+x2) + (y1+y2)i c1*c2 = (x1*x2-y1*y2) + (x1*y2+x2*y1)i 输入格式: 输入在一行中给出4个实数，分别代表c1和c2的实部和虚部。 输出格式: 在两行中分别输出c1+c2和c1*c2的计算结果。 输入样例: 1 1 -2 3 输出样例: addition of complex is -1.000000+4.000000i product of complex is -5.000000+1.000000i

以下是实现该功能的 Python 代码：

def complex_addition(x1, y1, x2, y2):
    # 计算两个复数的和
    real_part = x1 + x2
    imaginary_part = y1 + y2
    return (real_part, imaginary_part)

def complex_multiplication(x1, y1, x2, y2):
    # 计算两个复数的积
    real_part = x1 * x2 - y1 * y2
    imaginary_part = x1 * y2 + x2 * y1
    return (real_part, imaginary_part)

# 输入两个复数的实部和虚部
x1, y1, x2, y2 = map(float, input().split())

# 计算两个复数的和
addition_real, addition_imaginary = complex_addition(x1, y1, x2, y2)
print("addition of complex is {:.6f}+{:.6f}i".format(addition_real, addition_imaginary))

# 计算两个复数的积
multiplication_real, multiplication_imaginary = complex_multiplication(x1, y1, x2, y2)
print("product of complex is {:.6f}+{:.6f}i".format(multiplication_real, multiplication_imaginary))

输入样例：

1 1 -2 3

输出样例：

addition of complex is -1.000000+4.000000i
product of complex is -5.000000+1.000000i
