c语言考试报名管理系统代

好的，以下是一个简单的 C 语言考试报名管理系统代码示例，仅供参考：

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

#define MAX_NAME_LEN 20
#define MAX_ID_LEN 10
#define MAX_RECORDS 100

typedef struct {
    char name[MAX_NAME_LEN+1];
    char id[MAX_ID_LEN+1];
    int score;
} Record;

void add_record(Record records[], int *num_records);
void print_records(Record records[], int num_records);

int main() {
    Record records[MAX_RECORDS];
    int num_records = 0;
    int choice;

    do {
        printf("Welcome to the exam registration system!\n");
        printf("1. Add a new record\n");
        printf("2. Print all records\n");
        printf("3. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                add_record(records, &num_records);
                break;
            case 2:
                print_records(records, num_records);
                break;
            case 3:
                printf("Exiting...\n");
                break;
            default:
                printf("Invalid choice. Please enter a valid choice.\n");
        }
    } while (choice != 3);

    return 0;
}

void add_record(Record records[], int *num_records) {
    if (*num_records == MAX_RECORDS) {
        printf("Error: Maximum number of records reached.\n");
        return;
    }

    printf("Enter student name (max %d characters): ", MAX_NAME_LEN);
    scanf("%s", records[*num_records].name);

    printf("Enter student ID (max %d characters): ", MAX_ID_LEN);
    scanf("%s", records[*num_records].id);

    printf("Enter student score: ");
    scanf("%d", &records[*num_records].score);

    (*num_records)++;
}

void print_records(Record records[], int num_records) {
    if (num_records == 0) {
        printf("No records found.\n");
        return;
    }

    printf("%-20s%-10sScore\n", "Name", "ID");
    printf("--------------------------------\n");
    for (int i = 0; i < num_records; i++) {
        printf("%-20s%-10s%d\n", records[i].name, records[i].id, records[i].score);
    }
}

这个程序可以让用户添加考试记录，包括学生姓名、学生 ID 和考试成绩，并且可以打印所有已添加的考试记录。
