如果编码不一致，则在编译时会出现下面的错误:

||=== Build: Release in Josephus (compiler: GNU GCC Compiler) ===|
D:\work\cs\c++\datastruct\Exercise\Josephus\main.cpp||In function 'int main()':|
D:\work\cs\c++\datastruct\Exercise\Josephus\main.cpp|34|error: converting to execution character set: Illegal byte sequence|
D:\work\cs\c++\datastruct\Exercise\Josephus\main.cpp|36|error: converting to execution character set: Illegal byte sequence|
D:\work\cs\c++\datastruct\Exercise\Josephus\main.cpp|38|error: converting to execution character set: Illegal byte sequence|
D:\work\cs\c++\datastruct\Exercise\Josephus\main.cpp|40|error: converting to execution character set: Illegal byte sequence|
||=== Build failed: 4 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

设置办法:

文件编码：
Setting -> Editor ->General settings -> Encoding settings

此处默认Windows-936即gbk

编译编码：
Setting -> Compiler -> Global compiler settings -> other compiler options

在框中输入：
    -finput-charset=GBK
    -fexec-charset=GBK

如果需要跨平台, 建议都设置为 UTF-8, 即

-finput-charset=UTF-8
-fexec-charset=UTF-8
