References in C++

References in C++ References are similar to pointers in that they directly access the memory address of an object. However, unlike with pointer syntax, we do not need to explicitly assign a reference to a memory address. Instead, we can just assign a reference to the value itself. This way, we can modify the value without having to explicitly dereference like with a pointer. The downside however is we cannot reassign a reference so once we assign a reference, it will forever refer to that memory address. Therefore, a reference is basically a const pointer without the pointer syntax. In addition, we can declare a reference to a const. This is known as const reference, however note that this refers to the value being const, not the reference itself.
