Example Program: Part 5

{

complex a(1.4, 4.2);

complex b(2.3, 4.0);

complex c;

c = b - a;

printf(“a: real part %.2f, imag part %.2f\n”, a.real(), a.imaginary());

// a: real part 1.40, imag part 4.20

printf("%s minus %s is %s\n", b.print(), a.print(), c.print());

// 2.30+4.00i minus 1.40+4.20i is 0.90-0.20i

if (a == b)

printf("a is equal to b\n"); // no output

if (a == b-c)

printf("a = b-c!\n"); // a = b-c!
