Finish a class called Complex for complex numbers. Write the full runnable program with this class. Following requirements should be satisfied:
(a) Use double variables for the private data.
(b) Provide a constructor with default values.
(c) Provide functions support arithmetic calculation of adding and subtracting with Complex number objects.
(d) Provide function printing Complex numbers in the form “a + bi”.
class Complex
{
private:
double r;
double i;
public:
Complex(double, double); // Constructor with two arguments
Complex(double ); // Constructor with one argument
Complex(); // default constructor
Complex operator+ (Complex&); //Operator overloading
Complex operator- (Complex&);
void print(); // prints the complex number
};
main() function:
int main()
{
double ar,ai,br,bi,cr;
cin>>ar>>ai>>br>>bi>>cr;
Complex a(ar,ai);
cout << "Constructor with two values: a = ";
a.print();
Complex b(br,bi);
cout << "b = ";
b.print();
Complex c(cr);
cout << "Constructor with one value: c = ";
c.print();
c = a + b;
cout << "a + b = ";
c.print();
Complex d;
cout << "Default constructor: d = ";
d.print();
d = a - b;
cout << "a - b = ";
d.print();
return 0;
}
Example input:
1 2 3 4 5
Example output:
Constructor with two values: a = 1 + 2i
b = 3 + 4i
Constructor with one value: c = 5 + 0i
a + b = 4 + 6i
Default constructor: d = 0 + 0i
a - b = -2 - 2i
