Answer to Question #191810 in C++ for Flux

Question

Construct the class Complex that has floating point data members for storing real and imaginary parts and perform complex number subtraction using operator Overloading.

he class Complex has the following member functions:

Complex() - Null constructor invokes when an object is created

Complex(float, float) - Parameterized constructor to set the specified value of real and imaginary parts in object

Operator()- To subtract an object from another object

print() - Function to display complex number object

Test Case: 1

INPUT:

R1:15

I1: 2

R2: 5

I2: 10

OUTPUT:

A =15 + i2

B = 5 + i10

C = 10 + i(-8)

Answer 1
