运用一维数组设计一个员工工资管理系统,有查询修改功能.(console下的程序)
数组是提供好了的,里面存的是员工的工资.
int gz[]=new gz[5];
gz[0]=1100;gz[1]=1400;gz[2]=1800;gz[3]=1100;gz[4]=2000;
提示:
利用个while生成一个用户菜单供用户选择,第1项为查询员工数据,第2项为修改员工工资,第3项为结束系统.
当用户选择1或2时,先要求用户输入员工编号就是数组下标,程序再判断是否正确的员工编号,若正确,
刚显示员工工资,若错误,提示,"the error employee number!"
若用户选2项时,再进一步要求用户输入修改后的员工工资,并将数据存回员工工资数组中.

private int gz[]=new int[5];
