好的，我知道這被新手C++用戶問了很多，因爲我已經閱讀了大量的帖子，但即使在閱讀答案後，我也沒有看到我做錯了什麼。代碼很長，所以......儘可能寬容。轉發聲明錯誤駕駛我堅果
#include "dateType.h"
using namespace std;
void dateType::setDate(int y, int m, int d)
{
y = year;
m = month;
d = day;
}
int dateType::getYear() const
{
return year;
}
int dateType::getMonth() const
{
return month;
}
int dateType::getDay() const
{
return day;
}
void dateType::getDate(int& year, int& month, int& day) const
{
return (year, month, day);
}
bool dateType::operator==(const dateType& otherDate) const
{
return (getYear() == otherDate.getYear() && getMonth() == otherDate.getMonth()
&& d == otherDate.getDay());
}
bool dateType::operator!=(const dateType& otherDate) const

我還在上.h文件的工作，但我試圖測試只是類的初始化中的main.cpp文件。
dateType first_date(2014, 10, 31);
我得到了一些錯誤，但最先是： dateType.cpp：13：43：錯誤：無效的使用不完全類型 '類dateType' 無效dateType ::的setDate（INT Y的， int m，int d）
請告訴我我錯過了什麼。
非常感謝。
在'setDate'：'Y =年; m =月; d =日;'笏？ – user657267 2014-10-31 05:08:50
哎呀，一點小小的疏漏。謝謝。 – Blackwell 2014-10-31 05:09:05
@Blackwell如果你使用的是gcc或clang，用'-Wall -Wextra -Wpedantic-WeffC++'把警告變成11，它們可以幫助你捕捉這樣的簡單錯誤。 – user657267 2014-10-31 05:09:58
