When should static_cast, dynamic_cast and reinterpret_cast be used?
I'm using c function in c++, where a structure passed as a void type argument in c is directly stored that same structure type.
eg in C.
void getdata(void *data){
Testitem *ti=data;//Testitem is of struct type.
}
to do the same in c++ i use static_cast:
void foo::getdata(void *data){
Testitem *ti = static_cast<Testitem*>(data);
}
and when i use reinterpret_cast it does the same job, casting the struct
when i use Testitem *it=(Testitem *)data;
this does the same thing too. But how is the structure gets affected by using the three of them.
