An example of an AI chatbot conversation about pointers and references in C++ programming.
What are pointers and references in C++?
Pointers are variables that store memory addresses, while references are aliases for existing variables.
Can you explain how to declare a pointer?
To declare a pointer, you use the syntax: type *pointerName; For example, int *ptr;.
How do I use a reference in a function?
You can use a reference in a function by declaring the parameter with an ampersand, like this: void func(int &ref) { ... }.
What are the advantages of using references over pointers?
References are safer and easier to use since they cannot be null and do not require dereferencing.
