要开发一个记账本程序，你可以选择使用不同的编程语言和工具，根据你的需求和熟悉程度来定制。下面我将提供一个基本的Python记账本程序的示例，以及一个简单的C++记账本程序的框架。
Python 记账本程序示例
```python
import csv
from datetime import datetime
class AccountBook:
def __init__(self, filename='account_book.csv'):
self.filename = filename
self.headers = ['日期', '类型', '金额', '备注']
初始化CSV文件
try:
with open(self.filename, 'x', newline='', encoding='utf-8') as f:
writer = csv.writer(f)
writer.writerow(self.headers)
except FileExistsError:
print(f"{self.filename} 已存在，请选择其他文件名或覆盖现有文件。")
def add_record(self, record_type, amount, description):
with open(self.filename, 'a', newline='', encoding='utf-8') as f:
writer = csv.writer(f)
writer.writerow([datetime.now().strftime('%Y-%m-%d'), record_type, amount, description])
def view_records(self):
try:
with open(self.filename, newline='', encoding='utf-8') as f:
reader = csv.DictReader(f)
for row in reader:
print(row)
except FileNotFoundError:
print(f"{self.filename} 不存在，请先创建。")
def calculate_totals(self):
try:
with open(self.filename, newline='', encoding='utf-8') as f:
reader = csv.DictReader(f)
income = 0
expense = 0
for row in reader:
if row['类型'] == '收入':
income += float(row['金额'])
elif row['类型'] == '支出':
expense += float(row['金额'])
return {'总收入': income, '总支出': expense}
except FileNotFoundError:
print(f"{self.filename} 不存在，请先创建。")
使用示例
account_book = AccountBook()
account_book.add_record('收入', 1000, '工资')
account_book.add_record('支出', 500, '食物')
account_book.view_records()
print(account_book.calculate_totals())
```
