Assigning Addresses to PointersAssigning Addresses to Pointers

When working with pointers, proper initialization is essential to ensure they point to valid memory locations and prevent unexpected behavior.

Address-of and Dereference operators

To assign a value to the pointer we have to use address-of operator and to access the value of the memory address we have to use dereference operator.

  • &: the address-of operator, returns the memory address of its operand;
  • *: the derefence operator, returns the value that stored in the memory address.
cpp

main.cpp

Using the address-of operator, we can assign these addresses to pointers, creating a direct link between the pointer and the memory location it points to.

Завдання

  • Declare a pointer with an appropriate data type.
  • Initialize it with a variable memory address.
  • Output both the memory address the pointer points to and the value it holds.
