專案：建立一個公司員工的結構體，儲存員工的姓名、工齡、年齡。
要求：在主函式裡建立5個結構體陣列，從終端輸入資訊，分別以工齡排序和年齡排序輸出，排序方式自定。
程式碼如下：

#include <iostream>
#include<string.h>
#include<stdio.h>
//建立員工資訊的結構體
struct Staff
{
	char name[20];
	int seniority;
	int age;
};
//錄入員工資訊
void scanfStaInf(struct Staff* information)
{
	printf("請輸入員工姓名：");
	scanf("%s", information->name);
	printf("請輸入員工工齡：");
	scanf("%d", &information->seniority);
	printf("請輸入員工年齡：");
	scanf("%d",&information->age);
	printf("---------------\n");
}
//迴圈錄入
void scanfStaInf1(struct Staff* array,int elength)
{
	for (int i = 0; i < elength; i++)
	{
		scanfStaInf(&array[i]);//呼叫錄入員工資訊的函式
	}
}
//比較年齡，由小到大
int compareAge(struct Staff*p1, struct Staff*p2)
{
	if (p1->age == p2->age)
	{
		if (p1->seniority > p2->seniority)
		{
			return p1->seniority > p2->seniority;
		}
	}
	return p1->age > p2->age;
}
//比較工齡,由小到大
int compareSeniority(struct Staff* p1, struct Staff* p2)
{
	if (p1->seniority == p2->seniority)
	{
		if (p1->age>p2->age)
		{
			return p1->age > p2->age;
		}
	}
	return p1->seniority >p2->seniority;
}
//使用氣泡排序
void orderBySta(struct Staff* arry, int elength, int (*compareSeniority)(struct Staff* p1, struct Staff* p2))
{
	for (int i = 0; i < elength-1; i++)
	{
		for (int j = 0; j < elength-1-i; j++)
		{
			if (compareSeniority(&arry[j],&arry[j+1]))
			{
				struct Staff temp = arry[j];
				arry[j] = arry[j + 1];
				arry[j + 1] = temp;
			}
		}
	}
}
//列印資訊
void printStaInf(struct Staff Print)
{
	printf("name:%s seniority:%d age:%d\n", Print.name, Print.seniority, Print.age);
}
//迴圈陣列
void circulation(struct Staff* Print,int length)
{
	for (int i = 0; i < length; i++)
	{
		printStaInf(Print[i]);//呼叫列印資訊的函式
	}
	printf("----------------\n");
}

int main()
{
	//建立5個結構體陣列
    struct Staff Information[5];
    //錄入員工資訊
    scanfStaInf1(Information, 5);
	//呼叫排序,按工齡排序，工齡相同，則看年齡
	orderBySta(Information, 5, compareSeniority);
	//讀取員工資訊
	circulation(Information,5);	
	//呼叫排序，按年齡排序，年齡相同，看工齡
	orderBySta(Information, 5, compareAge);
	//讀取員工資訊
	circulation(Information, 5);
	
 

}
