Pointers
Hello, i started to learn C++ 1 week ago, i am at Pointer lesson (here) , and i don't understand , what pointers do , when to use, can somebody explain me in clear and short words. I also want some exercise based on pointers, to understand much better. Thanks.
A pointer is a type of variable that contains the address in memory of some other variable. For example, a pointer to an int (if appropriately initialised) contains the address in memory of an int.
I'l lleave it to someone else to recommend exercises.
Thanks grumpy for reply) ,it helped me to understand a little.
For an "exercise", make use of a linked list in your next program. Linked lists are like arrays, but you can extend them without replacing the entire data structure, which is one of their strengths over arrays.
