Hello everyone, how can I add a char to a char-array by using a other class? For example: class A { private char[] text; this() { ... text ~= "a"; new B(text); writefln(text); ... } } class B { this(char[] text) { ... text ~= "b"; ... } } This should write "ab" in the command line, but only "a" is shown. ... Thanks for help :).
