题目内容:
用结构体定义时钟类型,编程从键盘任意输入两个时间(例如4时55分和1时25分),计算并输出这两个时间之间的间隔。要求不输出时间差的负号。结构体类型定义如下:
typedef struct clock
{
int hour;
int minute;
int second;
} CLOCK;
函数原型: CLOCK CalculateTime(CLOCK t1, CLOCK t2);
函数功能:计算并返回两个时间t1和t2之间的差
程序运行结果示例1:
Input time one:(hour,minute):4,55↙
Input time two: (hour,minute):1,25↙
3hour,30minute
程序运行结果示例2:
Input time one:(hour,minute):1,33↙
Input time two: (hour,minute):5,21↙
3hour,48minute
输入提示: “Input time one:(hour,minute):”
"Input time two: (hour,minute):"
输入格式: “%d,%d”
输出格式:“%dhour,%dminute\n”`

{
CLOCK t3;
if (t1.hour >= t2.hour)
{
if(t1.minute >= t2.minute){
t3.hour = t1.hour - t2.hour;
t3.minute = t1.minute - t2.minute;
}else{
t1.hour -= 1;
t3.hour = t1.hour - t2.hour;
t3.minute = t1.minute + 60 - t2.minute;

题目内容:
某校的惯例是在每学期的期末考试之后发放奖学金。发放的奖学金共有五种,每项奖学金获取的条件分别如下:
院士奖学金:期末平均成绩高于80分(>80),并且在本学期内发表1篇或1篇以上论文的学生每人均可获得8000元;
五四奖学金:期末平均成绩高于85分(>85),并且班级评议成绩高于80分(>80)的学生每人均可获得4000元;
成绩优秀奖:期末平均成绩高于90分(>90)的学生每人均可获得2000元;
西部奖学金:期末平均成绩高于85分(>85)的西部省份学生每人均可获得1000元;
班级贡献奖:班级评议成绩高于80分(>80)的学生干部每人均可获得850元;
只要符合上述条件就可获得相应的奖项,每项奖学金的获奖人数没有限制,每名学生也可以同时获得多项奖学金。例如姚明的期末平均成绩是87分,班级评议成绩82分,同时他还是一位学生干部,那么他可以同时获得五四奖学金和班级贡献奖,奖金总数是4850元。
现在给出若干学生的相关数据(假设总有同学能满足获得奖学金的条件),请编程计算哪些同学获得的奖金总数最高。
结构体类型定义如下:
typedef struct winners
{
char name[20];
int finalScore;
int classScore;
char work;
char west;
int paper;
int scholarship;
} WIN;
函数原型:void Addup(WIN stu[], int n);
函数原型:int FindMax(WIN student[], int n);
