Question

c语言编写三个函数分别求某学生三门课程总成绩和平均成绩和及格率

尽量简洁

Answer 1

struct Student{
char name[30];
double C; // 语文成绩
double M; // 数学成绩
double E; // 英语成绩
};

typedef struct Student Student;
/* 学生的总成绩 */
void Total(Student* st){
printf("总成绩: %.2f\n", st->C+st->M+st->E);
}

void Avg(Student* st){
double x = (st->C+st->E+st->M)/3.0;
printf("平均分: %.2f\n", x);
}

void Pass(Student* st){
double x=0;
if(st->C >= 60){
x++;
}
if(st->E >=60){
x++;
}
if(st->M >= 60){
x++;
}
printf("及格率为: %.2f\n", x/3.0);
}

int main(){
Student st;
strcpy(st.name, "xiaoming");
st.C = 70;
st.E = 59;
st.M = 100;

Total(&st);
Avg(&st);
Pass(&st);
while(1);
return 0;
}
