统计学生成绩c语言分支结构

统计学生成绩可以使用C语言中的分支结构来实现。可以通过输入学生的各科成绩信息，计算出每个人的总成绩，并根据总成绩进行排名和统计。以下是一个简单的示例代码：

#include <stdio.h>
#include <stdlib.h>

#define MaxLength 255

//数据元素
typedef struct {
    int id;//学号
    char name[20];//姓名
    int score[5];//英语、政治、专业课1、专业课2的成绩
    int total;//总成绩
} studentElement;

//顺序表结构
typedef struct {
    studentElement studentArray[MaxLength];
    int length;
} seqList;

//初始化函数
int InitList(seqList* seqList) {
    int n;
    printf("请输入学生人数：");
    scanf("%d", &n);
    seqList->length = n;
    for (int i = 0; i < n; i++) {
        printf("请输入第%d个学生的信息：\n", i + 1);
        printf("学号：");
        scanf("%d", &seqList->studentArray[i].id);
        printf("姓名：");
        scanf("%s", seqList->studentArray[i].name);
        printf("英语成绩：");
        scanf("%d", &seqList->studentArray[i].score[0]);
        printf("政治成绩：");
        scanf("%d", &seqList->studentArray[i].score[1]);
        printf("专业课1成绩：");
        scanf("%d", &seqList->studentArray[i].score[2]);
        printf("专业课2成绩：");
        scanf("%d", &seqList->studentArray[i].score[3]);
        seqList->studentArray[i].total = seqList->studentArray[i].score[0] + seqList->studentArray[i].score[1] + seqList->studentArray[i].score[2] + seqList->studentArray[i].score[3];
    }
    return 1;
}

//统计函数
void Statistics(seqList* seqList) {
    int sum = 0;
    int max = seqList->studentArray[0].total;
    int min = seqList->studentArray[0].total;
    for (int i = 0; i < seqList->length; i++) {
        sum += seqList->studentArray[i].total;
        if (seqList->studentArray[i].total > max) {
            max = seqList->studentArray[i].total;
        }
        if (seqList->studentArray[i].total < min) {
            min = seqList->studentArray[i].total;
        }
    }
    printf("总分：%d，平均分：%d，最高分：%d，最低分：%d\n", sum, sum / seqList->length, max, min);
}

int main() {
    seqList seqList;
    InitList(&seqList);
    Statistics(&seqList);
    return 0;
}
