int和string類型互換

 #include
<sstream>

void int2str(const int &int_temp,string &string_temp)
{
        stringstream stream;
        stream<<int_temp;
        string_temp=stream.str();   //此處也可以用 stream>>string_temp
}

void str2int(int &int_temp,const string &string_temp)
{
stringstream stream(string_temp);
stream>>int_temp;
}
