What are the differences between pointers and references in C++?

What are the differences between pointers and references in C++?

Pointers are variables that store memory addresses, while references are aliases for existing variables.

Can you explain how to use pointers in C++?

Sure! You declare a pointer using the '*' symbol, and you can assign it the address of a variable using the '&' operator.

What about references? How do they differ in syntax?

References are declared using the '&' symbol in the declaration, and they must be initialized when created.

Are there any situations where I should prefer one over the other?

Yes, use references for function parameters when you want to avoid copying, and pointers when you need to manage dynamic memory.
