这是一个问题：
编写一个互动计划，为12名员工（2名成员，一名计算机操作员，6名推销员，3名助手）的员工生成工资单，在一家小型化学家零售店工作。可以在必要时进行假设。工资单应显示员工编号，员工姓名，编号。本月工作天数，工资单生成日期，工资支付月份，付款详情，扣除额，总薪酬和净工资。
当我运行程序时，它表示无效指针，即使我没有使用指针 我可以让任何人告诉我这个程序中有什么错误吗？

答案 0 :(得分：0)
错误：
1）语法错误1：
char name[30][30], designation[20[20], empid[12][12]; // Bracket mismatch
2）语法错误2：
char designation[20[20];
designation = "clerk"; // What is this?? ..the invalid pointer error
3）自己休息或尝试使用-Wall选项进行编译。

here is a modified program, any feedback??
