自动售货机控制系统设计 要求： 设计制作一个自动售货机控制系统。 该系统能完成货物信息存储，进程控制，硬币处理，余额计算，显示等功能。 该系统可以管理四种货物，每种的数量和单价在初始化时输入，在存储器中存储。用户可以用硬币进行购物，按键进行选择。 系统根据用户输入的货币，判断钱币是否够，钱币足够则根据顾客的要求自动售货，钱币不够则给出提示并退出。 系统自动的计算出应找钱币余额、库存数量并显示。 -Vending machine control system design requirements: Design a vending machine control system. The system can complete cargo information storage, process control, coin handling, balance calculation, display and other functions. The system can manage four kinds of goods, the quantity and unit price of each in the initialization input, stored in memory. Users can use coins shopping button to choose. The monetary system based on user input to determine whether enough money, coins, according to customer requirements is sufficient Vending, coins were not given prompt and exit. The system automatically calculate the balance should be looking for coins, inventory number and displayed.
