Question

2. Enter, compile, and run Program 11.1.

Answer 1

#include <iostream>

using namespace std;

class Complex {
private:
    double realPart;
    double imaginaryPart;
public:
    Complex(double=0.0, double=0.0);
    void assignNewValues(double, double);
    void showComplexValues();
};

Complex::Complex(double real, double imag) {
    realPart = real;
    imaginaryPart = imag;
}

void Complex::assignNewValues(double real, double imag) {
    realPart = real;
    imaginaryPart = imag;
}

void Complex::showComplexValues() {
    char sign = '+';
    if (imaginaryPart < 0) sign = '-';
    cout << "The complex number is " << realPart << ' ' << sign << ' ' << abs(imaginaryPart) << "i\n";
}

int main() {
    Complex a, b, c(6.8, 9.7);

    b.assignNewValues(5.3, -8.4);
    a.showComplexValues();
    b.showComplexValues();
    c.showComplexValues();
    return 0;
}

The complex number is 0 + Bi The complex number is 5.3 - 8.4i The complex number is 6.8 + 9.7i
