Kotlin Program to Add Two Complex Numbers by Passing Class to a Function

class Complex(internal var real: Double, internal var imag: Double)

fun main(args: Array<String>) {
    val n1 = Complex(2.3, 4.5)
    val n2 = Complex(3.4, 5.0)
    val temp: Complex

    temp = add(n1, n2)

    System.out.printf("Sum = %.1f + %.1fi", temp.real, temp.imag)
}

fun add(n1: Complex, n2: Complex): Complex {
    val temp = Complex(0.0, 0.0)

    temp.real = n1.real + n2.real
    temp.imag = n1.imag + n2.imag

    return temp
}
 

Output:

Sum = 5.7 + 9.5i
