What are some common references in C++ functions?

Can you explain what references are in C++ functions?

Sure! In C++, a reference is an alias for another variable. It allows you to refer to the variable without copying it.

How do I declare a reference in a function?

You can declare a reference by using the '&' symbol in the function parameter. For example: void myFunction(int &x).

What are the benefits of using references instead of pointers?

References are safer and easier to use than pointers. They cannot be null and do not require dereferencing.

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

Certainly! Here's a simple example:

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

This function increments the value of the passed reference.
