利用结构计算sgpa的C程序

#include <stdio.h>

// 定义结构体表示课程信息
struct Course {
    char name[50];
    int credits;
    float grade;
};

// 计算SGPA的函数
float calculateSGPA(struct Course courses[], int numCourses) {
    float totalCredits = 0;
    float weightedSum = 0;

    for (int i = 0; i < numCourses; i++) {
        totalCredits += courses[i].credits;
        weightedSum += courses[i].credits * courses[i].grade;
    }

    return weightedSum / totalCredits;
}

int main() {
    int numCourses;
    printf("请输入课程数量：");
    scanf("%d", &numCourses);

    struct Course courses[numCourses];

    for (int i = 0; i < numCourses; i++) {
        printf("请输入第 %d 门课程的名称：", i + 1);
        scanf("%s", courses[i].name);
        printf("请输入第 %d 门课程的学分：", i + 1);
        scanf("%d", &courses[i].credits);
        printf("请输入第 %d 门课程的成绩：", i + 1);
        scanf("%f", &courses[i].grade);
    }

    float sgpa = calculateSGPA(courses, numCourses);
    printf("SGPA为：%.2f\n", sgpa);

    return 0;
}
