#include using namespace std; /* Pointers in C++ are a very important concept to get down, they allow you to access another variable's memory address, which in turn then allows you to read or write to that location in memory, and while this may sound difficult to those unfamiliar with C, like myself, the concept is easily applied in the language. to start "playing with pointers", we need a couple of additional operators, one being the asterix "*" and the other being the ampersand "&". the * is known as the dereferencing operator, and the ampersand is known as the reference operator, with this tidbit of information we can begin. */ //standard function that takes a pointer to the first element of an array, and a size that describes the length of the array, loop back to this when you encounter the function call later void print_array(int *arg, int size){ for(int i = 0; i < size; i++){ cout << *arg; //dereference pointer to display value arg++; //DO NOT dereference to increase the address space } } int main() { //first we need a pointer variable, we can declare one like so. int *point; //then we need some variable for our pointer to point to, this can be anything, including functions or class members but we will keep it simple. int a = 3; // now we can asign our address, to our variable, you may be thinking "ok, simple ill just do this 'point = a;'" but this will throw an exception, specifically itll say, "cannot convert 'int' to type 'int*'" so we do this point = &a; // the & operator specifies that we want the memory address of the variable "a", not the value 3 that is assigned to it. // once we have that we can then proceed to work with our pointer to do so we must remember to use our other operator "*" the dereference operator to access the value of our pointer cout << "Address: "<
