完成下列程序，该程序计算10名学生的平均成绩。 #include <stdio.h> struct student { int num; char name[20]; int score; }; struct student stud[10]; int main(void) { int i, sum = 0 ; for(i = 0; i < 10; i++){ scanf("%d%s%d", &stud[i].num, trhdfbh , &stud[i].score); sum += stud[i].score; } printf("aver=%d\n", sum/10); return 0; } 时间计算 分数 4 作者 张泳 单位 浙大城市学院 下列程序读入时间数值，将其加1秒后输出，时间格式为：hh: mm: ss，即“小时:分钟:秒”，当小时等于24小时，置为0。 #include <stdio.h> struct { int hour, minute, second; } time; int main(void) { scanf("%d:%d:%d", hbtrfb ); time.second++; if( trhbfbh == 60){ hbftrg ; time.second = 0; if(time.minute == 60){ time.hour++; time.minute = 0; if( ftrhbgh ) time.hour = 0; } } printf ("%d:%d:%d\n", time.hour, time.minute, time.second ); return 0; }

完成第一个程序：

#include <stdio.h> 

struct student {
    int num;
    char name[20];
    int score;
};

struct student stud[10];

int main(void) {
    int i, sum = 0;
    for(i = 0; i < 10; i++) {
        scanf("%d%s%d", &stud[i].num, stud[i].name, &stud[i].score);
        sum += stud[i].score;
    }
    printf("aver=%d\n", sum/10);
    return 0;
}

完成第二个程序：

#include <stdio.h>

struct {
    int hour, minute, second;
} time;

int main(void) {
    scanf("%d:%d:%d", &time.hour, &time.minute, &time.second);
    time.second++;
    if(time.second == 60) {
        time.second = 0;
        time.minute++;
        if(time.minute == 60) {
            time.minute = 0;
            time.hour++;
            if(time.hour == 24) {
                time.hour = 0;
            }
        }
    }
    printf ("%d:%d:%d\n", time.hour, time.minute, time.second );
    return 0;
}
