c++ - 错误 C2664 : in c++?

Question

for (int v = 0; v <= WordChosen.length();v++)
{
    if(Letter == WordChosen[v])
    {
        WordChosenDuplicate.replace(v,1,Letter);
    }
}

我收到这个错误

"Error 4 error C2664: 'std::basic_string<_Elem,_Traits,_Ax> &std::basic_string<_Elem,_Traits,_Ax>::replace(__w64 unsigned int,__w64 unsigned int,const std::basic_string<_Elem,_Traits,_Ax> &)' : cannot convert parameter 3 from 'char' to 'const std::basic_string<_Elem,_Traits,_Ax> &' c:\documents and settings\main\my documents\uni\2nd year\tp2\hangman\hangman\hangman.cpp 147 "

我只是在输入这行之后才得到错误

WordChosenDuplicate.replace(v,1,Letter);

Answer 1

或者

WordChosenDuplicate.replace(v,1,std::string(Letter, 1));
