基于文件的通讯录管理系统。通讯录个人信息包括姓名、性别、年龄、电话、地址。用文件读/写操作编程实现通讯录的增加、查找、显示、删除、修改功能，完成通讯录编程、成功运行。

以下是Python代码实现：

# 定义通讯录类
class AddressBook:
    def __init__(self):
        self.contacts = []

    # 添加联系人
    def add_contact(self, name, gender, age, phone, address):
        contact = {
            "name": name,
            "gender": gender,
            "age": age,
            "phone": phone,
            "address": address
        }
        self.contacts.append(contact)

    # 查找联系人
    def search_contact(self, name):
        for contact in self.contacts:
            if contact["name"] == name:
                return contact
        return None

    # 显示所有联系人
    def show_contacts(self):
        for contact in self.contacts:
            print(f"姓名：{contact['name']}，性别：{contact['gender']}，年龄：{contact['age']}，电话：{contact['phone']}，地址：{contact['address']}")

    # 删除联系人
    def delete_contact(self, name):
        for i, contact in enumerate(self.contacts):
            if contact["name"] == name:
                del self.contacts[i]
                return True
        return False

    # 修改联系人
    def modify_contact(self, name, gender, age, phone, address):
        for contact in self.contacts:
            if contact["name"] == name:
                contact["gender"] = gender
                contact["age"] = age
                contact["phone"] = phone
                contact["address"] = address
                return True
        return False

    # 保存通讯录到文件
    def save_to_file(self, filename):
        with open(filename, "w") as f:
            for contact in self.contacts:
                f.write(f"{contact['name']},{contact['gender']},{contact['age']},{contact['phone']},{contact['address']}\n")

    # 从文件中加载通讯录
    def load_from_file(self, filename):
        with open(filename, "r") as f:
            lines = f.readlines()
            for line in lines:
                data = line.strip().split(",")
                name, gender, age, phone, address = data
                self.add_contact(name, gender, age, phone, address)

# 测试代码
if __name__ == "__main__":
    address_book = AddressBook()
    address_book.load_from_file("contacts.txt")

    while True:
        print("请选择操作：")
        print("1. 添加联系人")
        print("2. 查找联系人")
        print("3. 显示所有联系人")
        print("4. 删除联系人")
        print("5. 修改联系人")
        print("6. 保存通讯录到文件")
        print("7. 退出程序")

        choice = input("请输入操作编号：")
        if choice == "1":
            name = input("请输入姓名：")
            gender = input("请输入性别：")
            age = input("请输入年龄：")
            phone = input("请输入电话：")
            address = input("请输入地址：")
            address_book.add_contact(name, gender, age, phone, address)
            print("联系人添加成功！")
        elif choice == "2":
            name = input("请输入要查找的姓名：")
            contact = address_book.search_contact(name)
            if contact:
                print("联系人信息如下：")
                print(f"姓名：{contact['name']}，性别：{contact['gender']}，年龄：{contact['age']}，电话：{contact['phone']}，地址：{contact['address']}")
            else:
                print("未找到该联系人！")
        elif choice == "3":
            print("所有联系人如下：")
            address_book.show_contacts()
        elif choice == "4":
            name = input("请输入要删除的姓名：")
            if address_book.delete_contact(name):
                print("联系人删除成功！")
            else:
                print("未找到该联系人！")
        elif choice == "5":
            name = input("请输入要修改的姓名：")
            gender = input("请输入性别：")
            age = input("请输入年龄：")
            phone = input("请输入电话：")
            address = input("请输入地址：")
            if address_book.modify_contact(name, gender, age, phone, address):
                print("联系人修改成功！")
            else:
                print("未找到该联系人！")
        elif choice == "6":
            address_book.save_to_file("contacts.txt")
            print("通讯录保存成功！")
        elif choice == "7":
            print("程序已退出。")
            break
        else:
            print("输入有误，请重新输入！")

该程序中，通讯录类`AddressBook`中包含了添加联系人、查找联系人、显示所有联系人、删除联系人、修改联系人、保存通讯录到文件和从文件中加载通讯录等方法。在程序运行时，用户可以通过输入操作编号来选择需要进行的操作，实现了通讯录管理系统的基本功能。
