用codeblock typeid(i).name()跟老師的不一樣，為啥嘞
????int?i;????cout<<typeid(i).name()<<endl;
輸出的是? ?i
int?main(){????Rect?re;????Circle?cl;????doSomething(&cl);????return?0;}void?doSomething(Shape?*test){????test->calc_area();????cout<<typeid(*test).name()<<endl;????if(typeid(*test)?==?typeid(Rect))????{????????Rect?*rect?=?dynamic_cast<Rect?*>(test);????????rect->the_rect();????}}輸出的是前面帶了個數(shù)字的類

是不是編譯器的原因

void?doSomething(Shape?*test) {???? ????test->calc_area();???? ????cout<<typeid(*test).name()<<endl;???? ????if(typeid(*test)?==?typeid(Rect))???? ????{???????? ????????Rect?*rect?=?dynamic_cast<Rect?*>(test);???????? ????????rect->the_rect();???? ?????} ?} ?int?main() ?{???? ?????Rect?re;???? ?????Circle?cl;???? ?????doSomething(&cl);??? ??????return?0; ??}codeblock復(fù)制出來不帶回車我也很絕望
