What are pointers and references in C++?

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 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 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.

Can you give me an example of a function using pointers?

Absolutely! Here's a simple example:

void increment(int* ptr) {
    (*ptr)++;
}

This function increments the value at the address pointed to by ptr.
