However, if the pointer is casted to void*, it will not change the sourcing address. 5. internal of static_cast/dynamic a derived class which has multiple parent classes into a base class: get the address of the derived instance. if the address is zero, return it. if the address is n...
Using run-time type information, it's possible to check whether a pointer actually points to a complete object and can be safely cast to point to another object in its hierarchy. Thedynamic_castoperator performs a run-time check to ensure that the operation is safe. It's better to design...

Data of any type can be passed to a thread by using an address. However, C lacks adequate provisions for passing any kind of pointer to a routine. Instead,pthread_createmust be declared with a specific pointer type. On the other hand,void *functions as a versatile pointer type, allowingp...

static_cast can be used to force implicit conversions (e.g., non-const object to const object (as in Item 3), int to double, etc.). It can also be used to perform the reverse of many such conversions (e.g., void* pointers to typed pointers, pointer-to-base to pointer-to-derived...
Given a base class pointer, we can cast it to a derived class pointer: void f (BankAcct* acct) { SavingsAcct* d1 = static_cast<SavingsAcct*>(acct); } This is called a downcast. The static_cast operator allows you to perform safe downcasts for non-polymorphic classes. ...
This code is reserving the place for addresses that will point to some int data. There are also void pointers, they have no type to point to, but they could be converted to some pointer of certain data type. Then to work with the pointers, you need to connect it to some object in ...
