如何将类对象作为对另一个头文件的函数的引用传递

I have main.cpp

我有main.cpp

#include "Customer.h"
#include "Driver.h"

 int main(){
   Customer o_customer;        //Customer class object
   //ManageMenu is a Driver.h method
      ManageMenu( o_customer );   //calling method

  return 0;
}

My Driver.h is just a .h and .cpp file which does not have any class in it. What it does is handles all the screen display method, sample

我的Driver.h只是一个.h和.cpp文件,里面没有任何类。它的作用是处理所有的屏幕显示方法,样本

#include "Customer.h"
void ManageMenu( Customer & customer );

and, here is the issue , I am not able to pass the object reference in this function and I also believe that it is valid too as it simply means that we are passing the reference to some function.

并且,这是问题,我无法在此函数中传递对象引用,我也相信它也是有效的,因为它只是意味着我们将引用传递给某个函数。

My Driver.cpp

#include "Driver.h"
void ManageMenu( Customer & customer ){
 //do something
   //calls the method of Customer's class
customer.AddDetails();

}

I am not able to pass the object, the error which I am getting in g++ is

我无法传递该对象,我在g ++中遇到的错误是

error: variable or field 'ManageMenu' declared void
error: 'Customer' was not declared in this scope
        'customer' was not declared in this scope
 void ManageMenu( Customer & customer );

Please help me out and do explain me where I am doing the mistake. THANKS!!

请帮帮我解释一下我在做错的地方。谢谢!!

In Driver.cpp you forgot to add

在Driver.cpp中你忘了添加

#include "Customer.h"
