C++編程題 用new運算符為壹個包含20個整數的數組分配內存，輸入若幹個值到數組，分別統計其中

#include?<iostream>

using?namespace?std;

int?main()

{

int?*p?=?new?int[20];

int?i?=?0;

while?(cin?>>?p[i])

++i;

cout?<<?count_if(&p[0],?&p[i],?[](int?n){return?0?<?n;?})?<<?endl;

cout?<<?count_if(&p[0],?&p[i],?[](int?n){return?n?<?0;?})?<<?endl;

delete?[]p;

return?0;

}
