Question

Write a program to input two complex numbers and implement multiplication of the given complex numbers.

Answer 1

For complex numbers (a + bi) and (c + di), multiply real and imaginary parts using (ac - bd) + (ad + bc)i.

real1 = int(input("Enter real part of first complex number: "))
imag1 = int(input("Enter imaginary part of first complex number: "))
real2 = int(input("Enter real part of second complex number: "))
imag2 = int(input("Enter imaginary part of second complex number: "))

real_product = real1 * real2 - imag1 * imag2
imag_product = real1 * imag2 + imag1 * real2

print("Product =", real_product, "+", imag_product, "i")
