Aprenda Assigning Addresses to Pointers

When working with pointers, proper initialization is important 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.

main.cpp


              12345678
            
#include <iostream>

int main()
{
	int variable = 10;
	std::cout << &variable << std::endl;
	std::cout << *(&variable) << std::endl;
}

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.

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.
