C语言实现：班级学生信息顺序存储、查询、插入与平均分计算

#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; } ######[AI写代码神器 | 1013点数解答 | 2024-07-20 20:28:31]
