用C语言写下面这个系统：教师工资管理系统 每个教师的信息为：教师号、姓名、性别、单位名称、家庭住址、联系电话、基本工资、津贴、生活补贴、应发工资、电话费、水电费、房租、所得税、卫生费、公积金、合计扣款、实发工资。注：应发工资=基本工资+津贴+生活补贴；合计扣款=电话费+水电费+房租+所得税+卫生费+公积金；实发工资=应发工资 － 合计扣款。 A、教师信息处理 (1) 输入教师信息 (2) 插入（修改）教师信息： (3) 删除教师信息： (4) 浏览教师信息： B、教师数据处理： (1) 按教师号录入教师基本工资、津贴、生活补贴、电话费、水电费、房租、所得税、卫生费、公积金等基本数据。 (2) 教师实发工资、应发工资、合计扣款计算。 提示：计算规则如题目。 (3) 教师数据管理 提示：输入教师号，读出并显示该教师信息，输入新数据，将改后信息保存。 (4) 教师数据查询： 提示：输入教师号或其他信息，即读出所有数据信息，并显示出来。 (5) 教师综合信息输出 提示：输出教师信息到屏幕。
