C++指针数组传参问题，小白一枚望大神回帖，谢谢~

Question

struct ITEM
{
unsigned int id_;
unsigned short level_;
};

void reset(ITEM* item[])
{

for (unsigned short i = 0; i < 3; i++)
{
item[i]->level_ = 3-i;
cout << item[i]->id_ << " " << item[i]->level_ << endl;
}
}

int main()
{
ITEM* item[10];
for (unsigned short i = 0; i < 10; i++)
{
ITEM tmp;
tmp.id_ = i;
tmp.level_ = i;
item[i] = &tmp;
cout << item[i]->id_ << " " << item[i]->level_ << endl;
}
reset(item);
system("pause");
return 0;

}

Answer 1

#include
using namespace std;
struct ITEM
{
unsigned int id_;
unsigned short level_;
};
void reset(ITEM item[])
{
for (unsigned short i = 0; i < 10; i++) //验证传入的数据的正确性
{
cout << item[i].id_ << " " << item[i].level_ <<"111"<< endl;
}
for (unsigned short i = 0; i < 3; i++)
{
item[i].level_ = 3-i;
cout << item[i].id_ << " " << item[i].level_ <<"222"<< endl;
}
for (unsigned short i = 0; i < 10; i++) //验证修改数据后的正确性
{
cout << item[i].id_ << " " << item[i].level_ <<"333"<< endl;
}
}
int main()
{
ITEM item[10];
for (unsigned short i = 0; i < 10; i++)
{

item[i].id_ = i;
item[i].level_ = i;
cout << item[i].id_ << " " << item[i].level_ <<"ddd"<<endl;
}
reset(item);
system("pause");
return 0;
