程序不能编译 大家给改下 ，谢了
编译器: Default compiler
执行 g++.exe...
g++.exe "G:\C++程序\员工记录系统\Datdbase.cpp" -o "G:\C++程序\员工记录系统\Datdbase.exe" -I"C:\Dev-Cpp\lib\gcc\mingw32\3.4.2\include" -I"C:\Dev-Cpp\include\c++\3.4.2\backward" -I"C:\Dev-Cpp\include\c++\3.4.2\mingw32" -I"C:\Dev-Cpp\include\c++\3.4.2" -I"C:\Dev-Cpp\include" -L"C:\Dev-Cpp\lib"
