利用C++写一个三国人物英雄按年龄排序的案例

理解并实现冒泡排序算法，加强写方法的好习惯，理解结构体数组及地址传递

设计一个英雄的结构体，包括成员姓名，年龄，性别;创建结构体数组，数组中存放5名英雄。
通过冒泡排序的算法，将数组中的英雄按照年龄进行升序排序，最终打印排序后的结果。

五名英雄信息如下：
{“刘备”,23,“男”},
{“关羽”,22,“男”},
{“张飞”,20,“男”},
{“赵云”,21,“男”},
{“貂蝉”,19,“女”},

#include 
#include 

using namespace std;

struct hero
{
	string name;
	int age;
	string sex;
};

void allocateSpace(hero heroarr[], int heroarrlength)
{
	string heroname[] = { "刘备","关羽","张飞","赵云","貂蝉" };
	int heroage[] = { 23,22,20,21,19 };
	string herosex[] = { "男","男","男","男","女" };
	for (int i = 0; i < heroarrlength; i++)
	{
		heroarr[i].name = heroname[i];
		heroarr[i].age = heroage[i];
		heroarr[i].sex = herosex[i];
	}
}

void BubbleSort(hero heroarr[], int heroarrlength)
{
	for (int i = 0; i < heroarrlength - 1; i++)
	{
		for (int j = 0; j < heroarrlength - 1 - i; j++)
		{
			if (heroarr[j].age > heroarr[j + 1].age)
			{
				struct hero temp1 = heroarr[j];
				heroarr[j] = heroarr[j + 1];
				heroarr[j + 1] = temp1;
			}
		}
	}
}

void printdate(hero heroarr[], int heroarrlength)
{
	cout << "按年龄冒泡排升序后，输出如下：" << endl;
	for (int i = 0; i < heroarrlength; i++)
	{
		cout << "英雄名字：" << heroarr[i].name << " "
			<< "英雄年龄：" << heroarr[i].age << " "
			<< "英雄性别：" << heroarr[i].sex << endl;
	}
}

int main()
{
	struct hero heroarr[5];
	int heroarrlength = sizeof(heroarr) / sizeof(heroarr[0]);

	allocateSpace(heroarr, heroarrlength);
	BubbleSort(heroarr, heroarrlength);
	printdate(heroarr, heroarrlength);

	system("pause");
	return 0;
