i am confused aboult the type_casting in c++,that is:

dynamic_cast <new_type> (expression)
reinterpret_cast <new_type> (expression)
static_cast <new_type> (expression)
const_cast <new_type> (expression)

I don't know how to using them and the difference between them,so c_liked type_casting is used when i begin to code,any one can give me some articles ,as well as source code ,about the four type_casting operator listed above?
thank you for your time!
