以下源代码总是出现如下编译错误，C:\Program Files\Microsoft Visual Studio\MyProjects\chong\s.cpp(12) : error C2143: syntax error : missing ';' before '+'
C:\Program Files\Microsoft Visual Studio\MyProjects\chong\s.cpp(12) : error C2350: 'complex::complex::complex' is not a static member
C:\Program Files\Microsoft Visual Studio\MyProjects\chong\s.cpp(12) : fatal error C1004: unexpected end of file found
Error executing cl.exe.

chong.exe - 3 error(s), 0 warning(s)
请问是什么原因？谢谢！
