c++类型转换

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;
