一：implicit cast

二：explicit cast

  • const_cast
  • static_cast
  • dynamic_cast
  • reinterpret_cast
    const char *pArray = "helloworld";
    //char *pNonConst = pArray;//cannot convert from 'const char *' to 'char *'
    char *pNonConst = const_cast<char*>(pArray);//right, ;
    //*pNonConst = 'a';//this is undefined
    //*pArray = 'b';//error:cannot assign to a variable that is const
    cout<<*pArray<<endl;
    cout<<*pNonConst<<endl;
