'''学生成绩管理系统'''是结构体数组的典型应用：

<syntaxhighlight lang="c">
#include <stdio.h>
#include <string.h>

#define MAX_STUDENTS 100

struct Student {
    int id;
    char name[50];
    float scores[5]; // 5门课程成绩
    float average;
};

void calculateAverage(struct Student *s) {
    float sum = 0;
    for (int i = 0; i < 5; i++) {
        sum += s->scores[i];
    }
    s->average = sum / 5;
}

int main() {
    struct Student gradebook[MAX_STUDENTS];
    int count = 0;
    
    // 添加学生数据
    gradebook[count].id = 1001;
    strcpy(gradebook[count].name, "张三");
    float tempScores[] = {85.5, 90.0, 78.5, 92.0, 88.5};
    memcpy(gradebook[count].scores, tempScores, sizeof(tempScores));
    calculateAverage(&gradebook[count]);
    count++;
    
    // 显示结果
    printf("ID: %d\nName: %s\nAverage: %.2f\n",
           gradebook[0].id, gradebook[0].name, gradebook[0].average);
    
    return 0;
}
</syntaxhighlight>

'''输出结果：'''
<pre>
ID: 1001
Name: 张三
Average: 86.90
</pre>
