It seems your getResult function expects to get second parameter by reference. You can't pass function result by reference. Assign it to actual variable first and then pass reference to that.

看来你的getResult函数希望通过引用得到第二个参数。您不能通过引用传递函数结果。首先将其分配给实际变量,然后将引用传递给它。

unsigned long sizeOfC = sizeof(c);
c->getResult(array1, &sizeOfC);
