现在有一个班的学生，学生包括学号、姓名、数据结构分数 1、建立一个顺序存储结构存储学生的信息 初始包含： 学号姓名分数 1王令98 3张成67 5陈晨74 2、查询学号为5号学生的姓名和成绩？ 3、向顺序存储结构中插入学号：8，姓名：李时，分数:89的学生信息，插入到顺序表中第 2号位置？ 4、计算顺序表中学生平均分？ 用c语言实现

#include <stdio.h> typedef struct { int student_id; char name[20]; int score; } Student; void insertStudent(Student students[], int *size, int position, Student newStudent) { for (int i = *size; i > position; i--) { students[i] = students[i-1]; } students[position] = newStudent; (*size)++; } float calculateAverageScore(Student students[], int size) { float sum = 0; for (int i = 0; i < size; i++) { sum += students[i].score; } return sum / size; } int main() { Student students[100]; int size = 3; students[0].student_id = 1; strcpy(students[0].name, "王令"); students[0].score = 98; students[1].student_id = 3; strcpy(students[1].name, "张成"); students[1].score = 67; students[2].student_id = 5; strcpy(students[2].name, "陈晨"); students[2].score = 74; // 查询学号为5号学生的姓名和成绩 for (int i = 0; i < size; i++) { if (students[i].student_id == 5) { printf("学号为5号学生的姓名：%s\n", students[i].name); printf("学号为5号学生的成绩：%d\n", students[i].score); break; } } // 插入学生信息 Student newStudent; newStudent.student_id = 8; strcpy(newStudent.name, "李时"); newStudent.score = 89; insertStudent(students, &size, 1, newStudent); // 计算平均分 float averageScore = calculateAverageScore(students, size); printf("学生的平均分为：%.2f\n", averageScore); return 0; } [2024-07-20 20:28:31 | AI写代码神器 | 1013点数解答]
