My Understanding of pointers

Here’s my understanding of pointers in the form of quick program to test.

	main.cpp : Defines the entry point for the console application.
	Program to test understanding of how pointers work in C++

#include <iostream>

// My Cheeky class, defined here for breivity
class MyCheekyClass {
	void SayHi();

void MyCheekyClass::SayHi()
	std::cout << "HI THERE" << std::endl;

int main()
	int ival = 42;
	std::cout << "The value of ival is: " << ival << std::endl;

	// A pointer holds the address of another object. 
	// We get the address of an object by using the & operator (address-of operator)

	// Define p as a pointer to int and initialise p to be the address that points to the ival object
	int* p = &ival;

	// The type of the pointer must match the type of the original object
	// double* invalidPointer = &ival; // This will not compile as ival is type int not a double
	// We can use the * operator (deference operator) to access the object. 
	// *p should equal 42
	std::cout << "The deferenced value of *p is: " << *p << std::endl;

	// We can assign the ival object by asigning to the result of the deference
	*p = 300;
	std::cout << "Assign new value of 300 \n";
	// ival and *p should return 300
	std::cout << "The new value of ival is: " << ival << std::endl;
	std::cout << "The new deferenced value of *p is: " << *p << std::endl;

	MyCheekyClass Cheeky;
	// Define a pointer that holds the address of the Cheeky object
	MyCheekyClass* CheekyP = &Cheeky;

	// To access the method SayHi() we can deference the pointer then call the method

	// Can also use the access operator: ->

    return 0;
