c语言信息管理系统代码学生表包括学号姓名缴费总额，缴费总额为派生属性，根据每位同学的缴费金额汇总而得，可以列表所有学生信息 缴费表包括缴费编号学号金额，如果学号没有被记录，则会显示找不到该学生，有学号记录才能进行缴费

你需要一个简单的C语言信息管理系统代码，其中包括学生表和缴费表的功能。学生表包括学号、姓名和缴费总额等字段，而缴费表包括缴费编号、学号和金额等字段。如果学号在学生表中不存在，则会显示找不到该学生，只有存在学号记录的学生才能进行缴费。下面是一个示例代码：

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

#define MAX_STUDENTS 100
#define MAX_PAYMENTS 100

struct Student {
    char studentID[10];
    char name[50];
    float totalPayment;
};

struct Payment {
    int paymentID;
    char studentID[10];
    float amount;
};

struct Student students[MAX_STUDENTS];
struct Payment payments[MAX_PAYMENTS];
int studentCount = 0;
int paymentCount = 0;

void addStudent() {
    struct Student newStudent;
    printf("Enter student ID: ");
    scanf("%s", newStudent.studentID);
    printf("Enter student name: ");
    scanf("%s", newStudent.name);
    newStudent.totalPayment = 0;
    
    students[studentCount] = newStudent;
    studentCount++;
    printf("Student added successfully!\n");
}

void addPayment() {
    struct Payment newPayment;
    printf("Enter payment ID: ");
    scanf("%d", &newPayment.paymentID);
    printf("Enter student ID: ");
    scanf("%s", newPayment.studentID);
    printf("Enter payment amount: ");
    scanf("%f", &newPayment.amount);
    
    int found = 0;
    for (int i = 0; i < studentCount; i++) {
        if (strcmp(students[i].studentID, newPayment.studentID) == 0) {
            students[i].totalPayment += newPayment.amount;
            found = 1;
            break;
        }
    }
    
    if (found) {
        payments[paymentCount] = newPayment;
        paymentCount++;
        printf("Payment added successfully!\n");
    } else {
        printf("Student not found!\n");
    }
}

void listStudents() {
    printf("Student ID\tName\t\tTotal Payment\n");
    for (int i = 0; i < studentCount; i++) {
        printf("%s\t\t%s\t\t%.2f\n", students[i].studentID, students[i].name, students[i].totalPayment);
    }
}

int main() {
    int choice;
    
    do {
        printf("\nInformation Management System\n");
        printf("1. Add Student\n");
        printf("2. Add Payment\n");
        printf("3. List Students\n");
        printf("4. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);
        
        switch(choice) {
            case 1:
                addStudent();
                break;
            case 2:
                addPayment();
                break;
            case 3:
                listStudents();
                break;
            case 4:
                printf("Exiting...\n");
                break;
            default:
                printf("Invalid choice! Please try again.\n");
        }
    } while(choice != 4);
    
    return 0;
}

这段代码使用了两个结构体 `Student` 和 `Payment` 来表示学生和缴费信息。通过 `addStudent` 函数可以添加学生信息，而 `addPayment` 函数用于添加缴费信息。`listStudents` 函数用于列出所有学生的信息。你可以根据需要进一步修改和优化这段代码。
