Re: [問題] 錯誤訊息

[suspect1 (嫌犯)]

請問以下是什麼意思？

memTest.cpp:77: error: passing `const std::string' as `this' argument of
`std::b asic_string<_CharT, _Traits, _Alloc>& std::basic_string<_CharT, _Traits, _Alloc>
::erase(typename _Alloc::size_type, typename _Alloc::size_type)
[with _CharT = c har, _Traits = std::char_traits<char>,
_Alloc = std::allocator<char>]' discards qualifiers


 string option("-a  2 ") ;
 size_t begin = option.find_first_not_of(' ',0) ;
 size_t  n = option.find_first_of(' ',begin);
       option.erase(0,n) ; <- 發生錯誤的地方
