<p>So i've recently read about Pointers and References but im still kinda confused on References.
My friend told me this: "pointer -> points at a variable and if you make operations with the pointer you are actually making operation with the variable
from that moment on, that pointer does not actually holds a value, everytime you make operations with it you are actually modifying the variable you point at"</p>

<p>"A reference looks at the value we make reference and gets its value. From that moment on, until we close the program both the refence and the initial value exist.
However since they are totally different changing one of them does not impact the other, at all"</p>

<p>Is this correct?
Im kinda confused with references can someone make a small example about them?</p>
