如何使用GETLIN向C++中的类输入值？

我认为我已经做了一切正确的工作，但我得到以下错误：

..\CS115_IP2_SolJohnston.cpp:107:2:错误：“Customer1”未在此范围内声明 Customer1.setCustName； ^

您试图在主customer1中使用未声明的对象。因此，声明一个Customer类型的对象，然后使用它

int main()
{
     Customer customer1; // instantiate Customer class
    Customer1.setCustName("");
    Customer1.setCustAddress("");

}

viewAddress的closing}之后的所有内容都属于main这样的函数。我刚刚添加了它，并将更新问题。它仍然存在错误，但它确实帮助它添加了错误，不是吗：我认为在尝试使用它之前，需要将Customer1声明为“Customer”类型。我只是将该Customer1设置为；，真不敢相信我竟然忘了！最初，我在处理以下行时遇到了问题：getlinecin，address；Customer1.setCustAddressaddress；还声明字符选择；在使用它之前。还要将Customer1的地址传递给ViewAddress而不是两个字符串：ViewAddress&Customer1；这真的帮助了我的理解
