What are some common references in C++?

In C++, references are used to create an alias for another variable. They are often used for function parameters.

Can you explain how references differ from pointers?

Sure! References must be initialized when declared and cannot be null, while pointers can be reassigned and can point to null.

What are the advantages of using references over pointers?

References provide safer syntax, avoid pointer arithmetic, and are easier to use in function calls.

Can you give me an example of using a reference in a function?

Certainly! Here's a simple example:

void increment(int &value) {
    value++;
}

This function increments the value of the integer passed by reference.
