hello all, i'm trying to use this code in MainClass but nothing works: struct Complex { double r; double i; public Complex(double rt,double it) { r = rt; i = it; } public static Complex add(Complex a,Complex b) { return new Complex(a.r+b.r,a.i+b.i); } public static Complex sub(Complex a,Complex b) { return new Complex(a.r-b.r,a.i-b.i); } public static Complex mul(Complex a,Complex b) { return new Complex(a.r*b.r,a.i*b.i); } }
does anyone have an idea for it?
