解答:

#include <iostream>
using namespace std;

typedef struct _CandyBar
{
	string brand;
	float weight;
	int calorie;
}CandyBar;

int main()
{
	CandyBar* snack = new CandyBar[3];
	snack[0] = {"德芙",2.1,20};
	snack[1] = { "箭牌",2.2,16 };
	snack[2] = { "阿尔卑斯",2.3,18 };
	for (int i = 0; i < 3; i++)
	{
		cout << "品牌:" << snack[i].brand << endl;
		cout << "重量:" << snack[i].weight << endl;
		cout << "卡路里:" << snack[i].calorie << endl << endl;
	}
	delete[]snack;

	return 0;
}

运行结果:

考查点:

• new分配数组内存

注意:

• 有new就一定要有delete,数组要加[]
