输入某个学生的信息(含学号,姓名,年龄,六门课程分数-高数/英语/c语言/工程制图/大学物理/信息论,它们的课程学分分别为4/3/4/3/3/3,计算课程总学分。c语言结构体代码
下面是一个简单的 C 语言结构体代码,用于输入学生信息并计算总学分:
```c
#include <stdio.h>
struct student {
int id;
char name[20];
int age;
float math_score;
float english_score;
float c_score;
float engineering_score;
float physics_score;
float information_score;
};
int main() {
struct student s;
float total_credits;
printf("Enter student ID: ");
scanf("%d", &s.id);
printf("Enter student name: ");
scanf("%s", s.name);
printf("Enter student age: ");
scanf("%d", &s.age);
printf("Enter math score: ");
scanf("%f", &s.math_score);
printf("Enter English score: ");
scanf("%f", &s.english_score);
printf("Enter C score: ");
scanf("%f", &s.c_score);
printf("Enter engineering score: ");
scanf("%f", &s.engineering_score);
printf("Enter physics score: ");
scanf("%f", &s.physics_score);
printf("Enter information score: ");
scanf("%f", &s.information_score);
// 计算总学分
total_credits = 4 * s.math_score + 3 * s.english_score + 4 * s.c_score +
3 * s.engineering_score + 3 * s.physics_score +
3 * s.information_score;
printf("Total credits: %f\n", total_credits);
return 0;
}
