c - 在C中切换功能

试图创建一个菜单驱动的员工数据程序。我不知道如何创建功能菜单，也无法使菜单选项正常工作，例如编辑先前输入的员工信息。我将不胜感激。当前出现的错误是


编辑员工功能：重新定义；不同的基本类型。
在main中，当我使用menu(&payroll)调用菜单函数时，错误消息是无法从input*转换为input。
同样在main中-函数employeeInfo(&payroll)给出错误消息，无法从input*转换为input。


如果您发现任何其他错误，我敢肯定我还会犯其他错误，请向正确的方向引导我。

最佳答案

从开始


  1.编辑员工功能：重新定义；不同的基本类型。


您需要向前声明函数原型。


  2. menu(&payroll)无法从“输入*”转换为“输入”。


您的函数声明和定义不匹配。


在声明中，您有void menu(input payroll);
在定义上，您有void menu(void){ //
你用menu(&payroll);打电话


以上三个都不同。坚持任何一个。


  3. employeeInfo（＆payroll）无法从“输入*”转换为“输入”。


同样，函数声明和定义之间不匹配。更改您的函数声明

void employeeInfo(input payroll);

至

void employeeInfo(input* payroll);
