(C++)有沒有高手可以幫我看一下..完全Compile不齣來@@ - 趣味新聞網

下面是我用Visual Studio 2005 Build时的error, 一样一样解释吧....
如果懒得看, 我把改过的版本重新传成附件, 您自己再比对看看吧....
====
1>------ Rebuild All started: Project: LAB, Configuration: Debug Win32 ------
1>Employee.cpp
1>f:codesvs2005labemployee.h(11) : error C2144: syntax error : 'void' should be preceded by ';'
Employee(string, string, int) 后面少了个分号 ;
1>f:codesvs2005labemployee.cpp(30) : error C2065: 'endl' : undeclared identifier
档案开头少了using std::endl;

1>EmployeeTest.cpp
1>f:codesvs2005labemployee.h(11) : error C2144: syntax error : 'void' should be preceded by ';'
同上面那个档案略过.
1>f:codesvs2005labemployeetest.cpp(11) : error C2065: 'Bob' : undeclared identifier
1>f:codesvs2005labemployeetest.cpp(11) : error C2065: 'Jones' : undeclared identifier
1>f:codesvs2005labemployeetest.cpp(12) : error C2065: 'Susan' : undeclared identifier
1>f:codesvs2005labemployeetest.cpp(12) : error C2065: 'Baker' : undeclared identifier
因为你的Employee()是收String型态, 所以如果你不自行生成Bob, Jones, Susan, Baker的String实体,
那么一个比较偷懒的方式就是把它们都加上"", 成"Bob", "Jones", "Susan", "Baker"这样.
1>f:codesvs2005labemployeetest.cpp(14) : error C2143: syntax error : missing ';' before '<<'
1>f:codesvs2005labemployeetest.cpp(15) : error C2143: syntax error : missing ';' before '<<'
Employee1.getLastName(); 和后面 << "; Monthly Salary: " <<  ....(略)
如果你要接着印后面的东西, getLastName()后面的分号 ; 就要拿掉.
如果你要分两行, getLastName() << endl; 然后再接 cout << "; Monthly Salary: " <<  ....(略)
1>f:codesvs2005labemployeetest.cpp(17) : error C2248: 'Employee::monthlySalary' : cannot access private member declared in class 'Employee'
1>        f:codesvs2005labemployee.h(21) : see declaration of 'Employee::monthlySalary'
1>        f:codesvs2005labemployee.h(9) : see declaration of 'Employee'
1>f:codesvs2005labemployeetest.cpp(17) : warning C4244: '=' : conversion from 'double' to 'int', possible loss of data
1>f:codesvs2005labemployeetest.cpp(18) : error C2248: 'Employee::monthlySalary' : cannot access private member declared in class 'Employee'
1>        f:codesvs2005labemployee.h(21) : see declaration of 'Employee::monthlySalary'
1>        f:codesvs2005labemployee.h(9) : see declaration of 'Employee'
monthlySalary是Employee的私有变数, 所以你不能直接从外部存取这个变数.
必须用Empolyee提供的成员函数setMonthlySalary()来设值.
所以其中一行要改成Employee1.setMonthlySalary(Employee1.getMonthlySalary() * 1.1);
另一行请照着改; 另外, 这里有一个double -> int的精度失真的warning在下面, 看你care不care.
1>f:codesvs2005labemployeetest.cpp(18) : warning C4244: '=' : conversion from 'double' to 'int', possible loss of data
1>f:codesvs2005labemployeetest.cpp(21) : error C2143: syntax error : missing ';' before '<<'
1>f:codesvs2005labemployeetest.cpp(22) : error C2143: syntax error : missing ';' before '<<'
这两个和前几段提过的是同一个问题, 都是分号 ; 加在不对的地方, 或者后面 << 接在不对的地方.

以上, 我只照个Visual C++ 2005显示的error帮您修一下, 至于程式逻辑我就没仔细看了.
总之先帮您build得过了, 至于程式在干麻运行的对不对, 这么晚了, 再说吧....zzZ

感谢楼上的高手喔
我是用g++在compile的
但是我现在compile出这个error

另外两个没问题了＠＠
再次感谢喔

因为您compile EmpolyeeTest.cpp, 它找不到Empolyee.cpp的symbol.
所以概念上您需要把个别的.cpp(或.c)用g++ -c 先compile出obj档.
然后再用link把所有.obj档link成一个可以执行的binary file出来.
如果您有像VC++, BCB, Dev-Cpp这类IDE软体可以帮您省下这些事.
您或许需要一个Make file, 不过我和make file或Linux-like的OS不熟.
在Windows下, 我用下面这行指令可以产生正确可以执行的binary.
g++ EmployeeTest.cpp Employee.cpp -o EmployeeTest.exe
如果您的确在Linux下, -o 那个.exe就没必要, 或者您可以自行置换.
也许直接叫EmplyeeTest; build完下 ./EmployeeTest 就可以执行了.

非常的谢谢你喔
我做好了
完全okay啦
:D


我想问一下喔
Visual Studio 要按哪里compile阿?
我怎么都找不到＝ ＝？ 我用2008的..
express edition

Visual C++上面的工具列按钮有一个很像播放软体Play功能的绿色箭头按纽.
[ |> ] 这个预设就是"build and run", 不过这个设定是可以改成只run不build的.
所以您要的compile功能其实就是主选单里的Build->Build或Rebuild Solution.
印象中预设VC++就会帮您把solution/project里的所有.c和.cpp档都compile.
并依Solution的name帮您产生.exe档; 相关设定可以在Project->Property改.
