银行管理系统c语言程序设计代码
银行管理系统C语言程序设计代码简介银行管理系统是一个用于模拟银行业务的计算机程序。
它可以实现用户账户的创建、存取款、转账等功能,同时还可以进行利息计算、账单管理等操作。
本文将详细介绍银行管理系统的设计和实现,包括系统的功能模块、数据结构和算法等内容。
功能模块银行管理系统主要包括以下功能模块:1.用户管理:包括用户账户的创建、修改、删除等操作。
2.账户管理:包括存款、取款、查询余额、转账等操作。
3.利息计算:根据存款金额和存款期限计算利息。
4.账单管理:记录用户的交易明细和账户余额变动。
数据结构银行管理系统使用了以下数据结构:1.用户账户结构体:包括账户ID、账户名称、账户类型等信息。
2.用户交易结构体:包括交易类型、交易金额、交易时间等信息。
3.用户账户链表:用于保存所有用户账户的信息。
4.用户交易链表:用于保存用户的交易明细。
算法设计银行管理系统使用了以下算法:1.用户账户创建算法:通过用户输入的信息创建新的账户,并将其添加到账户链表中。
2.存款算法:根据用户输入的存款金额,将其添加到账户余额中。
3.取款算法:根据用户输入的取款金额,从账户余额中扣除相应金额。
4.转账算法:根据用户输入的转账金额和目标账户ID,将相应金额从当前账户中转到目标账户中。
5.利息计算算法:根据存款金额和存款期限,计算相应的利息。
6.账单记录算法:将用户的交易明细和账户余额变动记录到交易链表中。
代码实现以下是银行管理系统的C语言代码示例:#include <stdio.h>// 用户账户结构体typedef struct {int accountId;char accountName[100];char accountType[100];float balance;} Account;// 用户交易结构体typedef struct {int accountId;char transactionType[100];float amount;char transactionTime[100];} Transaction;// 用户账户链表typedef struct {Account account;struct AccountNode* next;} AccountNode;// 用户交易链表typedef struct {Transaction transaction;struct TransactionNode* next;} TransactionNode;// 创建用户账户void createAccount(AccountNode** head, Account account) { // 创建新的账户节点AccountNode* newNode = (AccountNode*)malloc(sizeof(AccountNode)); newNode->account = account;newNode->next = NULL;// 将新的账户节点添加到链表中if (*head == NULL) {*head = newNode;} else {AccountNode* current = *head;while (current->next != NULL) {current = current->next;current->next = newNode;}}// 存款void deposit(AccountNode* head, int accountId, float amount) {AccountNode* current = head;while (current != NULL) {if (current->account.accountId == accountId) {current->account.balance += amount;break;}current = current->next;}}// 取款void withdraw(AccountNode* head, int accountId, float amount) {AccountNode* current = head;while (current != NULL) {if (current->account.accountId == accountId) {if (current->account.balance >= amount) {current->account.balance -= amount;} else {printf("Insufficient balance.\n");}break;}current = current->next;}}// 转账void transfer(AccountNode* head, int sourceAccountId, int targetAccountId, flo at amount) {AccountNode* current = head;while (current != NULL) {if (current->account.accountId == sourceAccountId) {if (current->account.balance >= amount) {current->account.balance -= amount;break;} else {printf("Insufficient balance.\n");}current = current->next;}current = head;while (current != NULL) {if (current->account.accountId == targetAccountId) {current->account.balance += amount;break;}current = current->next;}}// 利息计算float calculateInterest(float principal, int years) {float rate = 0.05; // 假设利率为5%return principal * rate * years;}// 账单记录void recordTransaction(TransactionNode** head, Transaction transaction) { // 创建新的交易节点TransactionNode* newNode = (TransactionNode*)malloc(sizeof(TransactionNod e));newNode->transaction = transaction;newNode->next = NULL;// 将新的交易节点添加到链表中if (*head == NULL) {*head = newNode;} else {TransactionNode* current = *head;while (current->next != NULL) {current = current->next;}current->next = newNode;}}int main() {AccountNode* accountList = NULL;TransactionNode* transactionList = NULL;// 创建账户Account account1 = {1, "John Doe", "Savings", 1000.0};createAccount(&accountList, account1);Account account2 = {2, "Jane Smith", "Checking", 2000.0};createAccount(&accountList, account2);// 存款deposit(accountList, 1, 500.0);// 取款withdraw(accountList, 1, 200.0);// 转账transfer(accountList, 1, 2, 300.0);// 利息计算float interest = calculateInterest(1000.0, 1);printf("Interest: %.2f\n", interest);// 账单记录Transaction transaction1 = {1, "Deposit", 500.0, "2022-01-01 10:00:00"};recordTransaction(&transactionList, transaction1);Transaction transaction2 = {1, "Withdraw", 200.0, "2022-01-02 11:00:00"};recordTransaction(&transactionList, transaction2);return 0;}总结银行管理系统是一个功能丰富的计算机程序,通过使用C语言进行设计和实现,可以实现用户账户的创建、存取款、转账等功能,同时还可以进行利息计算、账单管理等操作。
C语言 银行账户管理作业附源码
银行账户管理系统一、设计思路用结构体链表来存放个人银行账户的信息,通过静态分配结构体数组的大小,然后通过对链表的插入、查找、删除、排序、保存操作实现账户管理的功能。
程序退出时自动将内存中的数据保存到文件中,再次运行时程序会自动从文件中读取数据扫内存中。
程序启动时要求输入用户名和密码用户名:admin 密码:123456二、各个功能的实现1、建立账户功能:struct account *insert(struct account*head, struct account *new);该函数通过对链表进行插入操作,从而实现建立账户的功能。
2、显示所有账户功能:void print(struct account *head);对链表进行输出,列出所有账户。
3、按照账号搜索的功能:struct account *find(struct account*head,long account_num);对指针进行遍历,找到符合条件的数据。
4、按照账号删除账户:struct account *del(struct account*head,long account_num);对链表进行查找,如有匹配的则执行删除,若没有找的不做任何操作。
5、模拟取钱功能:struct account *Withdrawal (structaccount *head,long account_num); 用户输入账号,然后对链表进行查找,要求用户输入账户密码,若匹配则可进行取钱(对余额做减法)。
6、模拟存钱功能:struct account *saving(struct account*head,long account_num);与取钱类似,对余额做加法。
7、排序功能:struct account *order (struct account *head);根据账号对链表进行排序8、保存数据和读取文件功能:void save(struct account*head);save函数实现保存功能,退出程序时自动保存数据,再次执行程序时自动从根目录中读取文件数据。
