title: Can Pass by Reference also be called as Pass by Pointer?
body: <p>I am currently reading on the ways of passing arguments to C functions. And while reading I came to know that in C there are two methods to pass arguments as pass by value and pass by reference.
  Then again I read that we can pass a pointer to the variable as a parameter too.</p>
  <p><a href="https://beginnersbook.com/2014/01/c-passing-pointers-to-functions/" rel="nofollow noreferrer">The beginnersbook website this method is mentioned as pass by reference.</a></p>
  <blockquote>
  <p>In this example, we are passing a pointer to a function. When we pass a pointer as an argument instead of a variable then the address of the variable is passed instead of the value. So any change made by the function using the pointer is permanently made at the address of passed variable. This technique is known as <strong>call by reference in C</strong>.</p>
  </blockquote>
  <p>I know that we can pass a pointer variable or the address of the variable with &amp; operator when we need to change or access the original variable. I want to know whether this pass by pointer can also be called pass by reference.
  Is pass by pointer also a method of pass by reference?</p>
